tried to add some sense of features that are in the north west harbour area of gilbraltar and there effect on what seems at least on OSM as a disputed border.I hope I managed to get the relationships right though it would be good for someone with more experiance of these to check it went in the right order.

Marvelous Marble

OSMhyd showing hydrants in Wennigsen (Deister)

As an active firefighter I of course know about OpenFireMap. And I knew of highway=emergency_access_point way before the Weekly Task caused many more of them appearing in the database. But I always wanted to have something that is not a website, and something where I can customize what is shown.

Using the awesome library of Marble I was able to hack together OSMhyd, a Qt-based application that shows fire hydrants, water tanks and emergency access points. Of course this is far from complete, but maybe it serves someone else as inspiration.

If you are interested a bit more in the technical details and future directions I've written a bit more about that in my KDE related blog post.

Hiking with Mapillary – aftermath

Posted by malenki on 2 October 2014 in English (English)

View from Mt. Valamarës Part of a 360° panorama from Mt. Valamarës. Click to see all of it in good quality.

During four weeks of which I hiked about three I used mapillary as described in a previous blog post.
The result were 113.384 pictures with 596 GB size (on ext4 – on exfat it was 623 GB).
The maximum of pictures recorded during a day was 9000, the average per day 4500.
After review 101.261 pictures with 561 GB size (ext4) remained.

Hardware used (lent from the Mapillary company):

  • 2x 128 GB microSD card
  • 2x deltaco Powerbank 10 Ah
  • 2x short cables USB-A–µUSB- ~20 cm
  • 1x long cable USB-A–µUSB- ~100 cm
  • 1x Sony Xperia Z1 Compact (w/o SIM card)
  • 1x external 2,5" USB 3.0 drive 2TB
  • 1x OTG-Ycable (purchased on my own)
  • Anker 40W charging station (Amazon OSM affiliate link) with 5xUSB with 2A output each. My property, can really recommend it.

As of today I finally sent all the stuff back to Mapillary including the images which they will add to the database on-site. I'd need about 90 days to upload them…

A handful of images I uploaded during stays in Hotels. You can find these images here (a village) and here (a minor street in Tirana).

On the way


I used the phone with the app blindly: Start the app and start recording, put it front-to-back inside a phone cover which gets attached to the left shoulder strap of the backpack. One of the Powerbank batteries I put into the lid of the backpack, attached the long USB-A–µUSB to it and fastened it at the left shoulder strap. So the phone could be easily charged while walking. I mounted it upside down to connect it more easily to the cable but that doesn't matter since the app writes a orientation flag into the photos EXIF data which tells how the picture is to show.


Due to the cumbersomeness of disconnecting, dismounting and peeling the phone out of the cover to switch to panorama mode, take some pictures, switching to walking mode, start recording, putting it in the cover, mounting and connecting it to the charging cable again I mostly did not do so.
At viewpoints or when making short rests I usually just stood there, had a look at the landscape and turned myself slowly around my own axis to let the app make images of the panorama. Only rarely (at big rests on mountain peaks or when walking a city on mapping purposes with the phone in the hand) I bothered to take pictures in panorama mode.

I just hope that there will be software intelligent enough which can detect little to no movement (based on GPS data) and overlapping image contents to stitch panoramas automagically.

At the hotel

After four days both powerbanks and the phone would be discharged so I had to spend a night at a place with electric power supply. Once I was five days "in the wild" so the last day went without Mapillary pictures.

Since I left the magnet charging cable at home due to bad charging performance and for reducing weight I had to calculate when to charge the phone and when to copy data since both at the same time doesn't work when using an OTG cable. When I intended to leave the hotel after one night it was a good idea to have the phone's battery charged in the morning so I tried to reach the hotel with a still quite charged phone, start copying as soon as I was in my room and before going to bed started charging the phone. Since I had two 128GB µSD cards with me capacity was the smaller problem. It really would have been easier if I had taken the magnet charging cable with me.

Nice side effect: I was also able to copy photos from my camera to the hard disk.


What I experienced so far on


Battery life

I was lent the phone with two 10Ah batteries. With them it was possible to cover four days of hiking. But all the time the phone's statistics say 24% of the energy are consumed by the display. In my case without any use because the phone is mostly operated blindly – I could have done without display.
I installed the app BlackouT which dims the display but does not reduce the energy it needs. The app "screen standby" I found too, but to get it working one has to have the phone rooted and Busybox installed. Though the latter I managed I wasn't able to get root and the app working (during the trip in a hotel room).


Several times I had to reboot the phone since the app told me it could not access the camera. Not so often I had to reboot it due to the lack of recognized GPS satellites. Switching off the phone during the night reduces occasional reboots during the day, but does not eliminate them.
Although the camera is said to be a good one, it may only be a good one for smartphones. If you don't walk in the bright blazing direct sun there is a good chance the image is blurred due to slow shutter while moving.


Sometimes the phone got so hot it showed irreproducible behaviour. The only possibility was to reboot it.


The cover of the micro USB connector I attached and removed quite often. Soon the fitting didn't fit anymore and a little later went to pieces. Anyway I didn't dare to check if the phone is really waterproof. I preferred to have pictures during all the holiday to a drowned phone. The "worst" weather I used it was very light rain where I attached it to my rain coat in which I had glued a strip of loop fastener, too.

Software (Mapillary app)

Displaying pictures

Since I am no smartphone user at all I am not sure if this issue depends on Mapillary or a dedicated photo viewing app. Displaying the pictures taken is fine as long as there aren't too much of them and you want to see the most recent taken pictures (remember I took per average 4,5k pictures a day). You have to scroll down all the way by hand, you cannot grab the scroll bar and pull it down. And after you had a view at an image and went back to the list you are at its very top again. Even switching from displaying horizontal to vertical lets the list go back to the first image.

Error handling

As mentioned above, sometimes the app could not access the camera and crashed. When I experienced this live it was not too bad, but when it happens during recording I didn'tt realize this and walked on taking no more pictures. Even when I set the app to "make shutter noise when taking picture" it didn't not help much because after a while one becomes accustomed to the sound. Usually it took me a while to realize that the sound (and the recording) had stopped - especially in cases were the app takes pictures only now and then.
The same goes for "warn at $(certain_amount_of_memory_left)%". I am not sure if the phone did warn before, but once I discovered it showed up a message "picture could not be saved" after each picture taken. The SD card was full… Give the app a warning sound!


Invincible mode:

Due to the way I used the phone (described above) it was not easy to know the state it and the app were in. Often it happened that I set the app to recording, put it inside the cover and attached it to the shoulder strap – and there was no shutter sound. So to have a look what the issue is one needs to take the cover off again and peel the phone out. By the way most of the time the phone was connected to a spare battery to charge while walking which made "have a look at the display" still more complicated. It also happened that by pushing the plastic cover the touchscreen received input - and when this happened at the wrong place recording could stop. As "invincible mode" I suggest a kind of lock mode in which one has to enter a kind of unlock "code" – touching the buttons in a certain order – to be able to access the app.

Speech commands

Some speech commands to start/stop recording and switch the modes (walking/panorama) would be helpful.

Multi level panorama

Being on a mountain top one has a great view. So great even that making a panorama with only one row of images is not sufficient. With my "good" camera I usually take three rows for a big panorama:

  • Sky with a little horizon
  • Sky and horizon in equal parts
  • Horizon and below

Write level to Exif

Since it is very likely the phone is out of level while walking it could be useful to store the degree the camera is out of level to be able to correct the image easily.

Time lapse

Good sequences (not shaky, not blurred and well matching images) Mapillary could present as time lapse movies.

Post holiday


To review this amount of pictures I struggled a little to find the best way. Just putting all the images in one folder and looking at them one by one is a slow method to sort them out. A lot of picture viewers are really slow on such a task, especially if they create a file list. The viewer ''feh'' is fast at displaying images from a folder containing zillions of them. But it still would take a lot of time to watch picture by picture. I finally chose to create a folders per each day and hour which is easy because of the naming of the images: 2014_08_14_18_25_30_374.jpg (year, month, day of month, hour, minute, second, splitsecond) Inside a folder containing images this line creates folders for each day and hour and moves the regarding images there: for i in $(ls -1 | cut -d "_" -f 1-4| uniq); do mkdir "$i"; mv "$i"*g "$i"; done With the picture viewer geeqie and fast preview settings it doesn't take too long to sort the bad images out. I mostly scrolled fast the preview thumbnails to find them. For me "bad images" are unintended selfies, shaky, over- and underexposed ones or where the biggest part of the images is obscured by stuff in front of the lens (trekking poles, arm, hand etc.).

Duplicates, triplets and so on I mostly didn't remove since some intelligent automagism could create a panorama from several files. After reviewing some thousand images I started to name these and "real " panorama pictures by adding "pano" to their name. For the little parts of the journey I used transportation I also named the images accordingly.

Image content

When the way goes steep uphill the pictures show a close up of the path without much landscape, often with the trekking poles. When descending the opposite happens: A lot of images seem to show the same piece of the landscape but not the path on which one walks downhill slowly. Due to the walking movements it happens a lot that the phone goes alternating out of level to the right and to the left or shows alternating more of the left side of the path and then more of the right.
Really bad roads Mapillary cannot depict when the phone is mounted to a cars front screen. Either the car is too slow or it shakes too much. And when you hold the phone with your hands you sway it around a lot… In some days you can see how this looks on Mapillary – with the sequence from Kroi Bardhë to Kumbull.
As I wrote at the hardware section already: It is very hard to get unshaky pictures when walking around without bright sunlight. Using Mapillary in the early morning or late in the evening? No way you get good pictures with your smartphone.


When it comes to mapping it is of course not bad to have as much data available as possible. But loading all the images of just one day with JOSM requires a potent computer – and looking at each image for mapping gets soon tiring. You should still collect POI with your GPS/a matching app or make photographs of interesting POI with another camera to know, where the interesting parts to map are.

When you have uploaded all the images to Mapillary without local backup and want to map using them it gets difficult. You have the choice of either look at the images on the Mapillary site, draw your conclusions and use the editor of your choice. But for me being dedicated to JOSM this is an awful way to map with photos. Also the script ubahnverleih wrote to download images from Mapillary and get them into JOSM gives results which don't satisfy me. It creates a gpx file with the images embedded. Contrary to loading images directly into JOSM where you are able to scroll back and forward through them you have to click on each single icon to see the image thumbnail - and click once more to see it in high resolution. Afterwards you have to close two windows, too.

My recommendation: keep a local backup of the images until you are done with mapping.


  • Mapillary is a nice way to collect images during (holiday) activities without bothering too much about technology.
  • Due to hardware limitations of smartphones you need a lot of light to get good images.
  • While walking it is not easy to make good, leveled and not blurred images.
  • For mapping purposes (with JOSM): keep a local backup and still collect POI with another app/device to easily find the highlights of the journey.

Despite all worries, the 1kg extra load and some occasions I really cursed the stupid hardware¹ I want to thank the company Mapillary to enable me to collect that amount of data in remote regions of Albania. In some way every photo is historic but I think since Albania is a fast changing country and little known to most Europeans these images may get some attention.

¹ "Great! I walked that breakneck path, didn't fall down – and the camera didn't work and I have to spend some minutes for rebooting the phone and restarting the app!!1 %$§£Ω¤"

Since publishing this post I added some paragraphs, the image and fixed some minor errors

Who I am/Why I'm running for 2014 OSM US Board

Posted by eleanortutt on 2 October 2014 in English (English)

My name is Eleanor Tutt and I live in St. Louis, Missouri. I’m passionate about maps, open data, community action, and (of course!) OpenStreetMap, which luckily combines all three. Over the past year, I’ve been actively contributing to and growing a committed St. Louis OSM community. As a board member, I would help out in whatever way possible, and I would especially like to:

1) Encourage participation of neighborhood organizations/block leaders

My day job is serving as a one person “data and maps shop” for Rise, a community development non-profit serving a four county area. In this role, I partner with neighborhood leaders to help them access, map, and interpret a wide range of neighborhood-level data. Our work emphasizes identifying and mapping assets such as schools, playgrounds, restaurants, gathering spaces - essentially, ideal OSM points of interest. I see a great opportunity for OSM US to work more closely with neighborhood leaders who are residents of and experts on under-mapped areas. These leaders already advocate for their neighborhoods at public meetings, in the media, in conversations over dinner - I want to encourage them to advocate for their neighborhoods on OpenStreetMap as well. One of the things I emphasize when I explain OSM to these new editors is that OSM gives individual people the power to shape the narrative of their city. I encourage them to map what matters to their community.

2) Continue support for editathons/mapathons

We’ve had great luck growing our OSM editor base in St. Louis through editathons, several of which I have organized. Our Cherokee Street editathon had two locations with different activities on opposite ends of a diverse commercial street. We partnered with a local art gallery and used Field Papers to increase participation from residents walking by (who may not have been carrying laptops or smartphones). For our Build for STL editathon, I encouraged editors (including nine new editors who had not heard of OpenStreetMap previously) through a friendly competition, with a score board and a trophy made out of an old globe, mouse, and LED lights. For these events and others, support from the national level in terms of organizing, publicity, and education/tutorials about available tools has been key, and I’d love to contribute to that work.

As I add my name to the list, I see that there are already many other highly qualified candidates. If I am not elected, I still look forward to working with them and becoming more involved at the national level in 2015. I thank the OSM US community for giving me the opportunity to run!

Missing Maps London Mapathon 30/09/2014 Skills Matter

Posted by Tallguy on 2 October 2014 in English (English)

What an evening!

60+ willing volunteers with laptops in a room (Big thanks to Skills Matter) with a team of helpers & great things happened. We talked, they worked & occasionaly we answered questions or helped in some other way. Some of our team were elsewhere in the world giving feedback to our new mappers, and some more were learning & helping using web links. There are quite a few photographs on Facebook - search for Missing Maps Project.


Well, I've never seen anything so good so quickly. Our mappers coped with the squares magnificently, checking what had already been done, adding missing details, and marking the squares as complete. Validators checked the squares, corrected any slight errors, gave feedback (messaging system in the TM works extremely well for this) & marked the squares as validated - we do need more validators though - might have to see if we can train some of our more regular volunteers in this.

Our Team

You were terrific. They wouldn't have done it without you - the whole package is needed & I don't know the names to thank everyone. There will be many unsung hero's and you should have a warm glow inside from knowing that you helped to make it work. Advertising, contacts, paperwork, ordering pizzas, standing at the door, making the technical bits work, admin - more admin. There's a lot of work needed, and I for one am grateful that you helped to make it happen, On the night I was really pleased to see many helpers giving advice - Dan, Harry, Nataly, Ralph, Richard, to name just some who willingly gave their time & expertise.

& Now

Validating / Feedback - to come

I'll try to make sure that everyone who was at the session gets feedback on at least one of the squares they compete - it may take me a while though. Don't wait for the feedback, keep mapping & keep learning. Mistakes happen, when you find out you've been making one, see if you can go back over the squares you've already completed & correct your previous work. If the square has been validated, the validator has probably already corrected any small errors. Personally I spend part of my time researching & part of my time mapping - have a read through or any of the links from

I'd recommend that you sign up for HOT emails - this link for a howto:

If IRC is your thing then (obviously I'd recommend the HOT group!)

More to come

Mapping - there is plenty of scope - the Task Manager contains many worthwhile tasks / projects. We trained mainly in iD, but there are other map editing programmes and future mapathons will cover options. If this was your first mapathon you only saw the tip of the ice berg - there are other HOT volunteers adding names to villages & towns (have to be careful of the source, so there are special instructions on this), mappers who validate, and volunteers who write software - boredom is not an option!

Thanks for reading, and I hope to see more of you with HOT and the Missing Maps Project - let's get it mapped before the disaster happens!

My Manifesto for the OSM U.S. Board

Posted by robin27 on 2 October 2014 in English (English)

In order for OSM to grow, we need to get new people involved. The world of academia presents a fertile recruiting ground of students and professors alike. I believe that if young students understand the awesomeness of OSM, they will go on to be contributors and informal ambassadors.

I am running for the OpenStreetMap U.S. board to make this happen. As a cartographer and entrepreneur, I've worked with people from all walks of life and figured out innovative solutions to all sorts of problems. I like to think creatively about high-level and long-term issues, but I'm also extremely organized and detail-oriented. I love facilitating and am excited about the possibility of working with a team of talented, passionate mappers to take OSM to the next level.

I strongly believe in the mission to promote the wonderful, free and open map that is OpenStreetMap, but in the past, I haven't contributed much or gotten very involved. @lxbarth, I'm answering your call.

Feel free to reach out to me if you have any questions!

Check out the OSM U.S. Elections page here.

Posted by FTA on 2 October 2014 in English (English)

Over the past six months. I've taken a great interest in the HOT project...first dealing with flooding issues in Europe and the conflicts in the Central African Republic, now with the Ebola outbreak in Africa. This has been one of the more rewarding projects I have worked on in a while, providing the opportunity to directly impact disaster response operations--something I have been active with over the years previously through amateur radio. I am looking forward to continued work with HOT and hope that I can provide some "meta"-help with them in the future, beyond simply mapping.

links about indoor to self

Posted by Govanus on 1 October 2014 in English (English)

In the areas I work some concentrate on working in large land use polygons but my focus is on more detail so I'll be learning some more of these ideas for indoor mapping (mainly of the many complex buildings in the city).

Access to the internet is still low for me so updates might take a few weeks to put in...

Vital signs of maps - monthly maps of mapping progress in Iceland

Posted by Stalfur on 1 October 2014 in English (English)

I've now made two maps for Mapping Botswana to show people that even if a map looks inert when you look at it, behind the scenes a lot is happening, just not maybe in the area you are looking at now.

So I've created one for Iceland as well.

Running for OpenStreetMap US Board

Posted by iandees on 1 October 2014 in English (English)

Hello! I am Ian Dees, a current board member running to be a part of the next board. You can read more about my credentials in last year's diary post.

This year, I'd like to continue our focus on increasing diversity in OSM through scholarships, education, events, and communication. After lots of technical challenges around maintaining our membership and interest contact lists, I think we're finally ready to start sending friendly, community-oriented newsletters. I'm also excited to help the board and local community plan and execute one of the best OpenStreetMap conferences in the world.

OpenStreetMap has made huge gains in the United States. With OpenStreetMap US's help, I think we can make it even better, and I want to continue leading the way. With your vote, I think we can work together to make that happen.

Thank you!

I'm running for the OpenStreetMap US board

Posted by coleman on 30 September 2014 in English (English)

My name is Coleman McCormick, a geographer and software developer based in St. Petersburg, Florida.

I discovered OpenStreetMap sometime back in 2008 or 9, and have been an active contributor ever since. I run our local Tampa Bay-area mapping parties, mapathons, and other efforts through OSM Tampa Bay - trying to grow our community of contributors in the southeast. After over 4 years as a contributor, I still edit the map almost every day, gradually refining data all over, but focusing mostly on Florida and the southeast US. I've also contributed to response efforts through HOT since 2010.

Over the past few years I've given numerous talks on the subject of OpenStreetMap, working to outreach to tangent communities that may have an interest in mapping - but don't come from the traditional developer/tech background. I'm particularly interested in exposing OSM to lower education (K-12), fostering more contributors from related industries (not necessarily software or GIS), and promoting the use of OSM data in the commercial space. The company for which I work is composed of many OpenStreetMap devotees, and we've used our time and resources to build tools like Pushpin to make mapping simultaneously more fun and more accessible.

I'm running for the OSM US board because we have a fantastic base community, with tremendous growth potential over the next few years. The project has come so far even in the last 2 or 3 years, with an ever-increasing and diversifying range of side projects and interest groups collectively mapping the country together. I see tons of opportunity for growth and diversification, and hope to help increase both.

I am running for re-election to the OpenStreetMap US board - I'd love your vote on October 4th

Posted by lxbarth on 30 September 2014 in English (English)

Vote today. OpenStreetMap US elections are open now. You can vote until October 12th. If you are an OpenStreetMap US member, you have a ballot in your inbox. If you're not you can become one in minutes and still vote.

I'm running for re-election to the the OpenStreetMap US board to expand OpenStreetMap US as a convening organization for everyone.

Over my past two years on the board, we have doubled the size of the State of the Map US conference, expanded its appeal to non-traditional audiences, increased diversity with scholarships and a distinct cross-audience appeal, and supported over 70 mapathon events that you all have helped organize.

OpenStreetMap is about the combination of the community: individual mappers and businesses and the humanitarian community and governments. We will succeed even more if we make an even more open community for everyone to collaborate. Working with Martijn, John, Jim, Kathleen, Mele, and Ian has been incredibly rewarding and I'd like to continue this into a third year.

To create a better map, we need to continue to expand OpenStreetMap beyond its current limits to communities we're not talking to yet. We need to bring OpenStreetMap to a broader set of industries, organizations, and communities. This is also the key for creating more diversity in terms of gender, global presence and ethnicity. To become more diverse as a community we have to grow in numbers.

The key tool to accomplish these goals is the annual State of the Map US conference. I am looking forward to further hone this conference as a space for everyone to come together and share their vision for OpenStreetMap and for newcomers to become part of the community. OpenStreetMap is about bringing the community together and bringing new people into the community. This includes a continued international appeal. We are playing an important role to bring international community members to the US to meet with them and to discuss core OpenStreetMap improvements but also help grow OpenStreetMap internationally.

Lastly, I don't want to finish my note without this appeal: If you care about OpenStreetMap you should run. Never think that to be on the board of OpenStreetMap you need to fill some sort of profile. Whether you're an individual mapper, whether you're a teacher or business person or use OpenStreetMap at your nonprofit, whether you're famous on the mailing lists or whether you just opened your first OpenStreetMap account last week. Put your hat in the ring and help OpenStreetMap grow in the US and beyond!

I would love your vote on October 4th. To participate, all you need to do is become a member. You can do so now, in just a minute. Find a full list of all candidates on the OpenStreetMap Wiki.

Just noticed I've passed 350 edits

Posted by raykendo on 30 September 2014 in English (English)

Wow, time flies when you're making edits. I've already made over 350 of them, and didn't realize it until today.

I've moved around a bit the last few years. In that time, I've tried to maintain OSM wherever I've lived. I've straightened roads, added buildings and parking lots. I've worked on maproulette a number of times, crossing the country and the globe looking for inconsistencies. And as the missus and i are adopting from Africa, I've looked over our kids' country of origin and tried to fix a few things there.

As for the tools of my trade, I've pretty much relied on ID. I don't know if JOSM would be an improvement, since most of my work is done on a rinky-dink laptop with a track pad for a mouse.

In my early days, I probably made some errors in the stuff i added. I guess we all start out that way. It's part of the learning process. But it has been fun to watch the areas I've worked on grow and develop.

I support OSM because it's a great free community-based resource. It's interesting to see who has cared enough to fix this or that. I hope this good work continues.

Using relations for sculptures with multiple pieces

Posted by jgruca on 29 September 2014 in English (English)

There are three sculptures within biking distance that are actually composed of separate sculptures, but named and presented collectively. What was the correct way to tag these, I wondered? Sculptures are pretty straightforward to map but these didn't seem to directly map to the concepts of points, ways, or areas.

The first time I ran across this was with this piece at the Des Moines Art Center. As the name implies, it's actually three parts that are not physically connected in any way. At the time I had only a vague notion of what a relation was in OSM. It didn't make intuitive sense to tag each piece with the same data, duplicating information. So I just dropped a point on the center piece of the artwork and moved on.

Just north of that installation is an even better example -- "Standing Stones" comprises six separate enormous blocks of granite distributed all across the front lawn of the museum. Again I wasn't sure what made the most sense, so I tagged one of them and called it good.

By the third time I found a multi-piece sculpture, I realized I needed to figure out a better way to handle mapping. I had gained a little more confidence in OSM concepts and had switched to using JOSM for serious editing, and realized that a relation would probably make sense here. Unfortunately, the wiki makes no concrete recommendations on using relations with artwork.

A little bit of searching did reveal a mailing list post that implied I was on the right track:

There is also the case of sets; for example, four carvings which form a single artwork, but which are mapped as separate entities.

You could put the four carvings into a relation, and put the wikidata tag there (along with the name=* and tourism=artwork).

I took that as validation that I wasn't totally off-base, and set off to make it work. The first thing I found was that relations need to be given a type. What kind of type makes sense for a group of sculptures? The only one that didn't seem obviously wrong was "site", so I went with that.

After making the update, I realized I should have checked to see what everyone else has been doing. Taginfo verified that yes, people have been using relations with artwork. And the handy link over to overpass turbo revealed an example (relatively) close in Chicago.

The Chicago result was actually very similar to what I had wanted to do -- group more than one sculpture together. I was gratified to see the relation type was the same as what I had settled on. In this instance, each node in the relation was also tagged with tourism=artwork and artwork_type=sculpture. This made more sense to me than leaving them bare, so I added the tags to my relation members as well.

Most of the other examples of relations used for artwork were multipolygons rather than groups of distinct pieces. But there were a couple other instances of site relations of artwork, so I felt justified in the mapping scheme I arrived at.

Now I need to back and update the first two scuptures to use the better solution. I do wish there was a more appropriate relation type than "site", but I suppose it will do.

Local Knowledge

Posted by Synapsensalat on 29 September 2014 in English (English)

We have been on a very nice trip to the beach at Crosshaven. I brought my field map with me to map a bit. In the end we went a completely different way because we had a local with us to guide us. It was beautiful. But now I'm not sure if I should map the path we took. Locals wouldn’t show these ways even to new residents. But one thing is so important I would like to map it. But don't know how to tag it. It's an open well in the middle of what is now a sweet corn field. Basically it's an uncovered maybe 6 meter deep hole. Any suggestions?

Hi, everybody

I started my first edits much later than my (2010) signup. What can I say, I lurk. I've started small. I have named some residential streets that I'm familiar with.

Next I plan on filling in names for more streets, and updating the new shopping center in west Madison.
