We had just launched the Project NOAH and OpenStreetMap Mapping Initiative to map out critical facilities and communities in the Philippines as part of our efforts in enriching our risk datasets. We hope that with the information we can gather from OSM, we can create better visualization for disaster scenarios here in the Philippines. And after the social media blitz to promote the above-mentioned event, we had a "mini-mapathon" here at the office. Nevermind the extended hours here at the office.
After 28 frustrating days after I signed up, I finally figured out how can the online editor can be displayed properly on my web browser (darn language preferences!). Started editing datasets in my hometown and in Lucban, Quezon (where I studied in high school). Enjoyed the experience (more than 100 edits in just one seating, whew!). Still got to figure out mechanical edits though, as some earlier entries in my hometown have some errors. But I hope it will be easier compared to Google MapMaker wherein a novice mapper is clearly at the disadvantage and at the mercy of some "map-making trolls".
I will commit myself to make edits everyday (yes, I'll try to add this to my list of New Year's resolutions). I think this wouldn't be difficult as mapping really gives me a different kind of rush. I just hope that this somehow addicting activity won't meddle much on fulfilling other equally important (but less enjoyable) resolutions too (read: jogging regularly, reading a journal article a day).
Special regards to Mr. Maning Sambale for his great work with OSM and for encouraging others to contribute more in the mapping community. I hope my orgmates at GSUP and UP GE Club would also be active in this endeavor. Let's make the Philippines a country fun to map!
i have recently acquired a gps unit. a garmin device. and i have been look at ways to use osm to add detail to the gps maps the unit uses.
i can find the cycling route to the place i need to get to in google maps but have not been able to find the culvert they have routed the bike route under the highway through in OSM.
i want to put it on my gps.
so my task as i understand it is to edit the osm for the area and add the relevant info to either a private map that my gps will be able to see, or an osm that anyone can see. of course not everyone will need to go to the place i have to go to. but. you know. if it is indeed the most intelligent route, then it's worth sharing the information. if it's not passable because it's under 2 meters of snow, we could perhaps document that too.
and then transfer the file into the gps unit. bob's your uncle, as they say.
This land is loosely the land owned by Railway bodies like BRRB and NR. The BRRB section in the south near the Royal Mail office is being prepared for possible redevelopment, so the tags tried to reflect recent changes. The rail line was taken up in the last couple of years as part of the sale preparation process.
Here it is a wonderful area for mountainbiking. Unfortunately, the map around Altea is not always that nice for that purpose. The last months I have made a lot of corrections and additions. Also I have tagged the tracks and paths for mountainbiking. The results you can see when you download the Spain map from www.openmtbmap.org , which is directly based upon the database of openstreetmap.
Decided to join OSM to improve my town, and county. I also specialize in adding abandoned railroads and making existing ones more accurate. I think OSM could be invaluable to historians and people doing research, which is why I try to add these and other historic things. I'll be focusing on Kansas for now.
Walked to Goose Green, Ridge Wood, Chipping Sodbury High Street, Peg Hill and home.
In total we imported over 5000 buildings, 3000 postal adresses and 2500 properties
A lot of OSM-related things are in my head, so I should put them here in case anyone wants to help:
- Roll out route_master relations to London bus routes (Routes 21, 30 and 277 are starter conversions, for instructions see https://wiki.openstreetmap.org/wiki/Bus_routes_in_London).
- If the Central London Cycling Grid (CLG) gets introduced, then it's bye bye to the LCN for the area where the CLG will run... once the signs are up (source: http://www.tfl.gov.uk/roadusers/cycling/29172.aspx).
- Is the UK eligible for Humanitarian OSM Team attention given the recent events?
- Make my local area the densest in the world.
Having some fun while mapping for the Mount Kelud volcano eruption response ;)
It covers UK numbering for flats and split use buildings and all the other special things that crop up.
It is used by parts of the goverment to do the same process that we do when adding addresses on OSM when they put them into thier databases.
Just a quick note, re my previous one about the 'project' to fix the duplicate search results for US counties by linking the boundary relations.
I'm keeping a 'informal' worklist here... http://wiki.openstreetmap.org/wiki/User:Revent/Counties because I'm OCD and want to know they are all done.
Currently we have over 1100 counties done (out of about 3400), so approximately 1/3. More volunteers to do your local state welcome! :P Letting me know that an area has been done would also be nice, so I can mark it off the list.
ToeBee has a nice blog post about an efficient 'workflow' for fixing a state with JOSM here... http://ksmapper.blogspot.com/
This is an age old-debate: How should one marry up a landuse boundary and a road? Should, with the convenience of Bing Maps, we try and map the land use up to the edge the road on the image - or just connect it up with the road.
Initially when I started mapping I took the former approach, and kept things split. It wasn't until I had noticed somebody had mapped the pavement (or sidewalk for you yanks) along side a road in one village that I started to realise the error of my ways.
Landuse - is just that. The designation of the land - often this is split up by highways (roads and rivers etc). The issue we have is that the line on the map editor is one dimensional - there is no width information, so when we zoom in, the land use edge appears to end in the middle of the road. This is an easy mistake to make as it is what we see but we have to remember when the map is rendered, the road has a width to it and it is entirely sensible for the road to be the dividing section of different landuses.
The alternative approach would be to draw roads as areas themselves, defining the landuse as highway. This of course is a silly idea.
The messy bit arrives when there is another border for the landuse and road - in the form of a hedge or fence. This then gets confusing - where do you stick the hedge? If you stick it in the correct place then usually it's drawn over by the road when it renders. You can't join it on the highway node though, as there are usually a barrier on both sides of the road - and the highway is one-dimensional. Conundrum.
Whilst highways can already have the width defined, I don't think it's something that is really supported or widely used. I think perhaps in addition to this we need to think about having attributes that relate to the edging of roads - this could quickly get complicated though - what about where only one direction has a pavement? What if it has a pavement and a fence?
Recently, I've been trying to move tags on island nodes to its way (natural=coastline) following the best practice of One feature, one OSM element. The original place=island nodes were from an GNS import. Most of these islands now have a digitized coastline so it makes sense to add the place=island and all its tags to the ways.
To do this, I ran an overpass query to get all place=island nodes within a given boundingbox. Code is below:
<osm-script output="xml" timeout="25"><!-- fixed by auto repair --> <union> <!-- query part for: “place=island” --> <query type="node"> <has-kv k="place" v="island"/> <bbox-query s="4.061535597066106" w="111.57714843749999" n="21.166483858206583" e="127.11181640625"/> </query> </union> <!-- print results --> <print mode="meta"/><!-- fixed by auto repair --> <recurse type="down"/> <print mode="meta" order="quadtile"/><!-- fixed by auto repair --> </osm-script>
The result will show on the map like this:
Then, I clicked the "Export" link to download the data into JOSM.
Slowly, working my way on each island node, I transferred the tags to the coastlines. If there is no natural=coastline, I trace them using Bing's high-res imagery and then add the tags in the island nodes.
Right now, I'm focusing my efforts on smaller islands where the natural=coastline is on a closed way. I will start working on the islands relations once I finish the closed ways. Might take a while though (current count is ~2,500 nodes).
With OpenStreetMap looking virtually complete around Edinburgh, it is sometimes difficult to spot where to map next. Obviously there are a lot of data still to be added to the map, and overlays such as those produced by ITO maps  are very useful in highlighting those areas with missing attributes.
However, recently I have been finding the notes feature on the main map has been a really good source of "this needs checking". It then becomes a treasure hunt, to go to that location, and spot the discrepancy flagged up, check it out, and update the map as required. This gives me a great excuse to explore areas of the city that I would unlikely otherwise visit, and keeps me fit as an added bonus.
As the saying goes, "many hands make light work", and I think this is certainly true for tracking changes in OpenStreetMap. If many people can flag up potential errors, even if some are false positives, then it gives more experienced mappers a good incentive to update the local area that may otherwise become stale.
Plus, I almost always find something else nearby that is not on the map, which I can add in addition to the flagger "error". Something that I most likely would not have gone to visit if it were not for the OCD compulsion to close as many of the open notes as possible :)
So thanks to the developers who implemented the notes feature, and thanks to the anonymous contributor(s) that flag up possible shortcomings in the data.
They're a lot of updating needed to be done here.. We need people who can give contribution to update or generate a new information and provide some data, especially in Borneo :).
I think I am a lone ranger here.... :\
Hello, here the biggest dam on the Borneo island.. And there a lot of controversial issues arise regarding on this dam. For further information, click this link http://en.wikipedia.org/wiki/Bakun_Dam.
I used Landsat 8 and SRTM to generate polygon for this dam.
First off, thank goodness we have shape importers for JOSM. I would not have been able to add almost a dozen parks tonight without it!
So far, I'm really enjoying adding parks and trails to the maps. I rely heavily on my garmin image maps and, compared to anything else the OSM maps have been a great boon.
I look forward to adding all of the current parks to Travis, City of Austin and Williamson county in the coming weeks. Then the real fun of going to them and mapping out the trails! Hope this spring and summer have wonderful weather!
