However, I think it's time to start giving our buildings the next bit of love: addresses. I checked and found a stagnant import proposal from 2010. Maybe it's time to reboot that? If you're interested in importing addresses for San Francisco, join in the conversation on the San Francisco Address Import wiki page
The other thing that our buildings lack is height data. Perhaps we could import that too? I started a page for that discussion here: San Francisco Building Height Import. Feel free to let me know if that's a terrible idea.
I have avoided having and carrying a smartphone, for their lack of security, until now. I have a new CPO BMW X5 with a particularly uninformative dashboard engine display. I DL'd an app to display under the hood, and for that I needed a Galaxy S5.
Leveraging the value I DL'd OSMAnd+ intending to use it as general GPS tracker and route finder on my bicycle.

Here is my weekly update on my Outreachy project.
#Week No: Six
##Target Milestone: Adding content to the Export Tool
###Summary: Help and About pages need revision and the coming week will be utilized in that.
Fizemos mais um encontro da comunidade OpenStreetMap de Brasília no último sábado! Além de mim e de Linhares, tivemos a presença de Jadson e Luiz Carlos, que nunca haviam editado, mas que já possuíam interesse no OpenStreetMap.
Após nos encontrarmos em um café, saímos para mapear uma quadra comercial de Brasília. Essa quadra fica próxima do Setor Bancário e do Setor de Autarquias Sul, assim possui muitos restaurantes e é uma área onde circula muita gente durante a semana. Fizemos o mapeamento de todos os pontos de interesse utilizando um mapa impresso no Field Papers. Após a caminhada pela quadra, retornamos ao café para inserir os dados no OSM utilizando o iD.
No mês de agosto, pretendemos realizar mais um evento, dessa vez será no Calango Hacker Clube, o hackerspace de Brasília. Assim que confirmado, posto as informações aqui.
A new little feature for Potlatch 2: you can add a bookmark for your current location, accessible via a new 'Bookmarks' dropdown menu. Use the 'Add' button at the bottom of the menu to add a new one. It works pretty much like every bookmarks menu you've ever used, to be honest.
There's also a new trademark obscure keypress, 'N', which moves to the other end of the currently selected way.
Since some members of the Mapper of the month team have been on holiday and the people we contacted for an interview prefered to stay anonymous, we have to use this backup scenario of an interview of Escada. Nevertheless, we hope you enjoy reading it. The French and Dutch translation will be available later this week on osm.be.
When did you discover OpenStreetMap?
I have always walked a lot with the dogs. Until 2011 this were often the same walks, or walks that are described in the Lannoo-guides. We did not walk every weekend or evening because I also trained for and participated in agility-trails. Unfortunately my competition dog got injured and I had to stop with the sport. This meant that I would have more time for walks. Since I wanted to discover more of Belgium, I bought an outdoor GPS-device.
The idea was to download trails from dogsfriendly.be and follow those. From the moment that I found out that a good map for walking costed as much as the device, I started looking for cheaper alternatives. That's I how I arrived at garmin.openstreetmap.nl. The map that was available via that site, seemed sufficient for my purposes.
Soon after installing the map on the device, I noticed that several smaller paths and tracks were missing in my home town. I subscribed to the Belgian maling list to learn how I could add those missing pieces. I got plenty of advice and one user, Polyglot also showed me which other data was missing and how that could be added. At that moment, he mainly talked about house numbers and bus stops.
Do you use OpenStreetMap yourself ?
From the above, you can deduce that I use OpenStreetMap on my Garmin-device, from the moment I discovered it. Furthermore, I will always use openstreetmap.org when I want to let my friends know about the start position of a walk. From time to time I use Grapphopper](https://graphhopper.com/) or OSRM, to find out beforehand how long a trip will take. Both routing engines are now also available on the openstreetmap.org website.
Recently, I bought my first smartphone. The main reason was to allow me to start using OsmAnd for car navigation. During our hollidays I also used it as a guide in some towns.
How do you map ?
As said in the introduction, I take the dogs out for a daily walk. This means that almost every day I find something new to map. The evening walks are usually close to home, while I make little trips all over Belgium during the weekend. Most of those trips are planned so I will discover a new part of some walking network. A walking network is layed out by the tourist office and allows each individual to create her own walk using short routes between numbered nodes. Those networks are one of the things I map.
The evening walks are totally different. Some of those walks were along calm paths, because the dogs enjoy them so much, while others were typical survey walks. That mean walking up and down each street and writing down information, mainly house numbers. I have collected several thousand house numbers that way. Since the Flemish house numbers can now be imported, I do not do this type of walks as much as before.
Because I keep learning about new stuff that can be mapped, even a walk that I have done several times before can expose new data. I also started to photograph those streets for Mapillary. Although that is not always easy, especially with 4 dogs on a lead and when the sun is going under.
Which Tools do you use ?
From the first day on, I use a GPS-device to collect waypoints with information that I want to map later on. This works well for short texts, such as house numbers or objects that one meets frequently such as benches or garbage cans. I developed a whole "new" language based on abbreviations for this purpose.
Since a year or so, I take more pictures and rely less on waypoints. After all the relative position of objects is easier to see on photos. Furthermore, photos might contain details that you have missed while you were there. I take most pictures with a reflex camera. Sometimes, I try to use the smartphone as well. But in the end the GPS device and the camera are handier, since you can hang them around your neck and they are operated easily with one hand. I need the other hand to hold the leads of the dogs. I always upload the pictures to my smugmug-website, as an archive.
I immediately started mapping with JOSM for the improvement of the data. I have used the online editors, but they do not fulfil my needs. iD came in handy when I was working on some Maproulette tasks. Level0 was useful to quickly correct some tagging mistakes I made on a number of objects. I wrote a diary entry about that a while ago.
I have been working on correcting errors detected by Osmose and KeepRight, but I prefer to add new stuff that I surveyed. It seems to be that going out and collect data is more valuable as I have the impression that not a lot of people do that.
On the other hand, I enjoyed trying to fix the mistakes in my neighborhood listed by Check The Monuments. Probably, because I am more interested in that topic.
When I do not need my smartphone for navigation, I try to use it to take pictures with Mapillary. This allows me to take photos while I'm driving.
Where do you map ?
I map almost exclusively in Belgium. Of course, I also map during my holidays abroad. I have also mapped a few villages in Mongolia and Uganda. That is very relaxing, just tracing houses and path from aerial images. However, I prefer to map locally, where I am familiar with the environment.
What do you map ?
When I started mapping, I only payed attention to missing paths and the traditional Points of Interest (POI) such as shops, banks and mailboxes. It did not take long before I started mapping house numbers and bus stops. The list kept on growing when I added garbage cans, benches, picnic sites, life buoys, bicycle parkings etc.
Only during the last half year or so, I also started mapping underground fire hydrants (before that I did not know how to find them), street cabinets, markers for pipelines and the electricity cables for the local distribution. In the latter case, pictures found on Mapillary come in handy. The poles that hold those cables are often too small to be recognised on aerial images. That is perhaps the reason that they are not mapped a lot so far. There is a nice map that shows them though.
Of course, I also map the traffic signs for one ways, speed limits etc.
Since April 2014, I have been mapping the turn lanes in Flanders. Back then, I mapped a few of them, just to see the JOSM Lanes and Roads attributes style of Martin Vonwald in action. But I realised that this data could be very helpful for a car navigation program, so I continued mapping them, all over Flanders. One day I hope to be able to start in Wallonia. When I was mapping them for half a year or so, OsmAnd announced the support for this type of data. A few months later, the German community announced a project to focus on this data. They also developed a tool to view this data. It gives a nice feeling that others find this data also important.
During this virtual tour through Flanders, I occasionally saw some badly mapped crossings. However, in general the data seems complete and correct. On the other hand, I think that the data regarding the bicycle paths and lanes can be improved a lot. I have seen a lot of bad connections between the cycleways and the main roads. I also have the impression that a lot of oneway tags are missing on those cycleways, although that is hard to see on an aerial image of course. I fear that the navigation for cyclist is lacking in quality.
Thanks to the pictures on Mapillary, it is easy to map the destination signs. Finding the right picture can take some time, because the quality is not always good enough to read the signs. I hope that this will improve when more pictures become available. Those destinations are also used by OsmAnd, both on the display and as spoken navigation aids.
I also mapped many of the postal code boundaries. I had read on the German forum how they did it. Those relations turned out to be the solution to instruct Nominatim to return the correct postal code for an address. Other mappers have picked up this method and completed the postal code boundaries for Flanders. Unfortunately the administrative boundaries are often missing in Wallonia, so we cannot map the postal code boundaries.
Via Check the Monuments I discovered the historical places map. During my walks I had seen many signs for listed buildings, but never took the time to map them. In the meantime all listed buildings in Antwerp, Mechelen, Ghent and Bruges are mapped.
For each walk that I plan via a walking network, I also make a list of all historical buildings in the neighbourhood. I use a Python script that I wrote to generate a waypoint for each building. I find the list of those buildings, e.g in Sint-Pieters-Leeuw per town on wikipedia. When I am there, I check whether the building still exists and try to take a good picture of it. Those photos are placed on wikimedia. I also adapt the wikipedia page. Of course, all details about the buildings are added to OpenStreetMap.!
After meeting someone that had mapped the Japanese Garden in Hasselt during a meetup, I though that it would be neat to do something similar. So I visited the Open-Air Museum Middelheim (map) near Antwerp a couple of times in order to collect the data about the statues. In the meantime I should revisit the place to check the position of the statues, since they then to be moved from time to time. I also started a similar project to map all flowerbeds in the rose garden of the Vrijbroekpark in Mechelen.
Why do you map ?
I like to explore new areas. The surveys give me a good excuse to do that. And of course, mapping is more useful that endlessly watching YouTube movies of playing games. And I find it relaxing as well.
I also enjoy starting little projects and experiment with unknown tags, which is one of the reasons to start mapping new stuff. This keeps it interesting as well.
What is your biggest achievement as a mapper ?
It is hard to choose between my contributions to the walking networks, the protected monuments and the turn lane mapping.
Do you do other things than just mapping ?
I have given a few introductionary presentations, e.g on OpenBelgium 2015 and at some workshop organised by Nicolas Pettiaux at the ESI in Brussels.
Furthermore I have collected a few presets that I often use in JOSM with tagging specific for Belgium. Someone made that collection available under the name BENELUX. The name is not the best in the world, but I hope it is useful for some Belgian mappers.
I also made the original English translation for the Historic Places map and their JOSM preset. I still maintain the Dutch translation for that website. Not too long ago I translated a wiki page with Overpass examples from German to English. This should make it possible to use the page in a Google Summer of Code project.
I am also part of the Belgian Mapper of the Month Team. This idea was launched by Ben Abelshausen last winter. The purpose is to put another mapper into the spotlights every month. We hope that this helps to get to know each other better and improve the community feeling. The team looks for a mapper each month, writes him or her with the questions and makes the needed translations. In the end the text is available in Dutch and French on the Belgian OpenStreetMap website and in English in my diary. The latter is done to give more exposure to the idea.
I also made a few simple maps with umap. Via the "Doggy map", I tried to introduce my friends from the dog world to OpenStreetMap, in the hope they would start mapping e.g. off leash areas. The map Fritures was an attempt to give more exposure to a typical Belgian form of fast food restaurant. I think it motivated some existing mappers to add some missing fritures in their neighbourhood or to adapt some incorrect tags.
Do you have ideas to expand the OpenStreetMap community ? I think we need more user-friendly applications that use "our" data. OsmAnd and and Telenav's Scout (USA-only) are good examples of such programs. I think it is a pity that we do not have a possibility to plan walks along the walking route networks, something that is possible on the wandelknooppunt-website, but that is not using OpenStreetMap data. We have so much more data such a picnic sites, parkings, historical buildinds, taverns, etc. which might power a website that should allow a user to plan her walk much better in advance.
Too many website are still focussed on mappers and to do not pay enough attention to ordinary users. This seems like a problem to me, as most people just consume data, they do not produce data.
We might have to create some projects similar to the German "weekassignments" or the English "trimester assignments" for the Belgian mappers. Given the relative success of my posting about the umap with fritures, it might help to motivate the mappers.
What is the biggest feature of OpenStreetMap?
The large diversity of data that can be combined in interesting ways, see e.g. the article on the "Het Pad van Ad" by Polyglot that combines a walking route, public transport and tourism information.
What is the biggest Challenge for OpenStreetMap ?
I have the impression that too many mappers are too focused on what they see on openstreetmap.org. But, there are so many websites and applications. We should promote all of them more. Maybe the German, French or Belgian approach is better. First explain the visitors of the website that it is about the data, and that this data is used on many different websites and in different apps. After that, you can still show them a large example map. Right now, this map is still compared with Google and too many people complain that their favorite feature is not rendered as they wish.
How do you stay on top of OpenStreetMap related news ?
I try to follow about 15 mailing lists in 4 different languages. I learned a lot from the German forum. I discovered the Wochennotiz a few years ago and it seems to me that it is essential for anybody interested in OpenStreetMap. Luckily it is now also translated in several other languages. I also configured an alert on Google, which send me a mail message with new web pages related to OpenStreetMap. From time to time it contains a page that I did not see elsewhere.
Do you stay in contact with other mappers ?
I am rather active on the Belgian mailing list. I still have a lot of email conversations with Polyglot, who teached me a lot in my early days.
I try to participate in all kinds of gatherings with other mappers, such as meetups or introduction days. Furthermore I organized a few hangouts to explain some basic JOSM functionality to novice mappers. Such an introduction is not always easy via email.
When I have problems to tag something, I might directly contact other mappers for help. Sometimes the specialist cannot be found in Belgium and I do not always need the discussions that a mail to a public list generates. So far, that experience was very positive, I assume the reason is that everybody wants to make the map better.
I have been contacted myself regarding a feature that I mapped incorrectly. I was not sure of what it was, but I added a tag to a photo of the "thing". This allowed the specialist in that area to contact me, and tell me that it was a underground water reservoir for the fire department. I thought it was just an underground fire hydrant.
Anything else you want to share ?
I would recommend all beginning mappers to subscribe to the mailing list and ask for advice before starting any serious work. Not all information is provided by the editors.
Having purchased a Garmin GLO to "fix" the GPS problem I was having with my Nexus 5 I discovered:
- OSMtracker doesn't log fractions of a second, causing problems with points having the same time stamp and having tracks plot strangely in JOSM
- 10 Hz updating makes for really big files
I tried both GpsPrune and the simply way tool in JOSM but neither were entirely satisfactory. GpsPrune requires you to enter a "span factor" that is specified as a fraction of the total span of the trace (so you can't just enter a distance, you have to figure out what magic factor gives you the desired result for each trace), using JOSM you loose all of the elevation and HDOP data, and both of them have no way of specifying a maximum segment length.
- Log data in NMEA format using the Ultra GPS Logger app.
Simplify the track using GPS Babel:
gpsbabel -i nmea -f input.txt -x simplify,crosstrack,error=0.0005k -x interpolate,distance=0.195k -o gpx -F output.gpx
Using GpsPrune cut off the bits of the track you don't want and export to GPX.
Gzip the GPX file and upload it to OpenStreetMap.
The simplifying filter uses a cross track error of 0.5m which I've found to be a good compromise between the trace smoothness and the number of data points. The interpolation is needed because JOSM by default won't draw segments longer than 200 m. I originally used distance=0.2k but this gives you a dashed line effect as each alternative segment is just a little under and a little over 200 m and 0.195k ensures that every segment will be drawn.
Here is an example from a trip from Apollo Bay to Colac with 1900 points in just over an hour of travel.
Recently Google Research labs published details about http://googleresearch.blogspot.co.uk/2015/07/deepdream-code-example-for-visualizing.html "Deep Dream"
Its useful for visualizing how a neural net works - the neural net is asked to find images within other images. (usually its used to classify what's in an image) The result is hallucinatory, or dream like.
So I thought about how about what if we give it a map or two? here we go:

Здние университета им.Г.Р. Державина и здание Сбербанка
OSM is 3D capable, is sad that still the main page doesn't support 3D rendering with WebGL. Fortunately there are 3rth partners that do it like f4map. Kendzi plugin of JOSM is good but not enough and it only works in JOSM. After several reads the wiki of 3D buildings and trying to figure it out how the stuff works, and a lot of tries and errors, finally get some decent renders.
This is Torre Kuadra, a nice building of Quisqueya:
I was glad to lead an OpenStreetMap Workshop in Madina, Ghana. It was an introduction session and also building upon local community.

I uploaded all the GPS traces I collected while systematically biking every road in Regina last year. It should be useful for newer areas until the satellite imagery gets a refresh.
Roads added after mid-July 2014 won't have traces uploaded. I have traces for most of the new ones as I periodically bike through the areas under construction. But its a matter of figuring out which day I biked those roads. Its usually easier to just go back and ride them again.
Now that 0.9.6 is out, my focus is, naturally, on the next version. Hopefully 0.9.7 wont take quite as long to be ready, I'm fairly optimistic that we will be able to hit the planned release time frame of end of September. The larger operations on the guts of the app have already happened and should have enough time to stabilize till then.
If you are interested in what is planned see https://github.com/MarcusWolschon/osmeditor4android/issues?q=is%3Aopen+is%3Aissue+milestone%3A0.9.7 Two of the items have already progressed pretty far: putting the code in place for translating the presets and the integration of notification support.
The later was mainly written as a proof of concept early this year at the Karlsruhe hack weekend but needed some work to be really useful. Some images from Karlsruhe:
Alert on a watch (naturally works on phone too) from an error detected in the nearby OSM data
the same for a Note
and navigating to the location with OSMand
A test build with the inital (still needs a bit or work for production) alert support is available here: https://drive.google.com/folderview?id=0B9pKLmh8s1h8bFI5bGd4VnhYWkk&usp=sharing . You will need to turn on alert support in the advanced preferences and have "auto download" enabled in the GPS menu (if auto-download doesn't initially work try toggling the setting).
While I have your attention: one of the work items is redoing the Notes code to work more like the rest of Vespucci and allow offline use. Are there any specific wishes for how it should behave (I will likely leave a way to immediately save and close a note in the app, but the normal mode will be a bulk upload at the end of your surveying/editing session). If you have some suggestions please add them to: https://github.com/MarcusWolschon/osmeditor4android/issues/228

Idag har jag provat använda openstreetmap. Försökte märka ut ett gammalt slakteri i Vilhelmina som jag vart in i, men hittade inte exakt vart det var. Hittade åt det förra hösten när jag var ute och gick på en skogsväg och träffade en gubbe i skogen som tyckte vi skulle gå dit och kolla. Det hängde krokar i taket och på väggarna stod det "the dead end" osv. Tror inte dom är så intresserad av kultur på den orten annars hade det vart perfekt kulturhus. Det är ju många däruppe som köper upp billiga hus med stora källare som dom kan odla hasch i. Det hade vart en bra och naturlig brygga mellan alla hippieanarkister och skoter- och jaktmänniskor.
Gubben bodde i en husbil. Vi avslutade vår upptäcktsfärd med att titta på filmen "Jakten för livet" i hans husvagn. Det var ganska smutsigt därinne, när jag kom hem stoppade jag in strumpbyxorna i frysen och gick och duschade.

На прошлой неделе мы занимались образовательными учреждениями: школами, детскими садами и не только.
Ниже представлена статистика по этой теме с пояснениями.
Количество школ, обозначенных просто точками, уменьшилось, а линиями или отношениями - возросло. Это хороший результат: карта стала чуть более детальнее. Также может показаться странным, что общее количество школ уменьшилось. Но в этом нет ничего страшного: дело в том, что многие учреждения дополнительного образования и детские сады имели тег amenity=school.
Аналогичная ситуация с детскими садами:
Уже давно есть пропозал по обозначению заведений дополнительного образования. К ним относятся художественные, музыкальные, спортивные школы, а также автошколы и многое другое. В рамках этого недельного задания применялся данный тег, что показано на диаграмме ниже.
Кроме того, Kikenni предложил пойти ещё дальше и использовать теги из пропозала Реформы образования. Прирост в их количестве показан ниже. Надеюсь, количество этих объектов сыграет роль при голосовании за это предложение.
Ещё одним аспектом данного задания было исправление уже нанесённых школ, в частности стандартизация их названий. Об этом - на слайде:
И, традиционно, активность участников (количество отредактированных объектов каждым участником):
Кроме маппинга, была немного дополнена вики-статья о школах.
По данным сайта ResultMaps, участие приняли 5 человек. Они отправили 45 пакетов правок.
В данный момент: исправляем area=yes
This is probably a tutorial you want to look at when you have just created a changeset somewhere and you want to view it in OsmAnd on your phone offline. There is another tutorial but I tried to follow the instructions and I just didn't get it. So, apologies to the authors of that tutorial if I am basically repeating them, but here we go.
Getting the Data
- Go to overpass-turbo.eu
- Zoom to your area of interest (if need be do a search in the search toolbar)
- Push "Load", which is one of the options on the top bar; go to Examples, and hit Map Call. A query will appear in the left window pane
- In the map window, choose "manually select bbox" (there is a little box icon under the magnifying glass and random round "locate me" thing that does this)
- Move the bounding box with your mouse to reflect the area you want 5a. (optional) If you want to see what this will do in your browser, hit "Run". This will, however, take time, download more data (bad if you have a poor internet connection) and possibly complain about downloading too much data
- Hit "Export raw data directly from Overpass API"
Converting the Data
- A file will download, probably called "interpreter". Move that file to wherever you are working, and rename it (we suggest using the date of download and name of the area of interest as a file name). Remember to add the extension .osm to the end of your filename (example "2015-09-21 mytown.osm"). This is important is OsmMapCreator will not recognize it otherwise.
- Open OsmMapCreator - instructions for this can be found in the tutorial I mentioned before. If you are having problems with it, just download the file, unzip it and run the "batch" file in that folder. (You will have to see which of those items type=batch)
- In OsmMapCreator, choose File > Create .obf from .osm file
- Choose the .osm file that you just downloaded
- Wait more
- It will eventually show you a dialogue saying that it's created a file in a folder (probably something like c:/users/Yourname/osmand. You will need to locate this folder, and go find the .obf file, which will have the same name as your osm download, but with the .obf extension. Use cut and paste to get them into your working directory.
Putting it on your Phone
1.Close Osmand on your phone, put the .obf file on your phone in the osmand folder, and restart Osmand.
Hope this works for you :) Feedback appreciated!
