Strange GUI issues with JOSM and Ubuntu/Debian 5 days ago

Hint: When I search the JOSM issue tracker I always also look for closed bugs. One never knows… :)

OpenStreetMap POI finder 5 days ago

Sorry if I didn't say it clear: I don't get to see a single POI because I cannot select any category. The site looks like this when I try to do that: http://malenki.ch/d/2016-02-08_234140_scr_small.jpg

Additionally: A permalink would be nice, too. At the moment I have to scroll&zoom to my region each time I open the site.

OpenStreetMap POI finder 5 days ago

Well, in Chromium and Firefox the layer button on the top right just minimizes when I try to look for POI. IMHO it would be better to have a responsive search filed instead of a long category list to click around.
And that it only works for POI on nodes not ways is a serious drawback.

Sizes of various map formats 20 days ago

Thank you for the hint – I knew I should have looked for primary sources. *sigh* Though that OSMAnd page shows me 67,2MB.
I updated the posting accordingly.

My christmas gift for the OSM Community - JOSM Keyboard Shortcuts Cheat Sheet 300 DPI about 2 months ago

@baditaflorin: I have been a little too enthusiastic –
ctrl-"D" duplicates objects which is a JOSM core feature "Y" is a JOSM core feature as well.

My christmas gift for the OSM Community - JOSM Keyboard Shortcuts Cheat Sheet 300 DPI about 2 months ago

Nice work. Why don't you just save it at the OSM wiki or Wikimedia Commons?
Stuff I miss:
"X" stems from eXtrude – extruding a line - be it from a linear or closed way
"D" duplicates selected Objects
"B" switches to buildings_tools draw mode when the plugin is installed
"Y" toggles the viewer of geolocated images if loaded

About Huts about 2 months ago

A faster way of correcting the huts (utilsplugin2 required):

  • draw a way with the diameter of a hut
  • make it a circle by pressing Shift-O (maybe set the circle node count to an appropriate value previously)
  • select this newly made and the old, oversized hut
  • press CTRL-Shift-G to replace the old way with the new one (this keeps the history of the already existing way)

Instead of always drawing a new hut I often just copied and then pasted one since a lot of them have the same size. Thus you would need even one step less – three instead of six.

For way vs node: What would you do if there was a rectangular hut instead of a circle shaped? Still use a node with radius, width or length? I find it easier to map the length of the way instead of describing it.
Additionally: It is surely more rewarding for (new) mappers to see their added buildings show up on the map instead of it remaining blank. (afaik building on nodes aren't rendered)

Mapping my hometown Rajahmundry 3 months ago

Have you tried using Mapbox Imagery?
Though its resolution isn't as good highways should be easy to map. Contrary to Bing Imagery there are only two sets of imagery end the offset is nearly zero (at the places I looked at). After you are done wit the highway grid based on Mapbox you can align Bing to the highways.

In case you use JOSM it may be easier to draw highways on an empty layer, then download the OSM data and use "replace geometry" to move the existing tags and object IDs vom the misaligned to the newly made, enhanced ways. "replace geometry" gets provided by the utils_plugin.

Welcome Message 3 months ago

http://www.openstreetmap.org/user/Glassman/diary/36237

I'd say the most important is: Make it short! Make it to the point!

At least when I think of how I handle "Welcome Messages" after registering my umpteenth account somewhere I skip every message which is longer than ~6 lines.
About a message with an essay as content I think: "I want to do XY which is why registered. The message I will read later – maybe."

Half of what you list (about, philosophy, donations) is already on osm.org or easily to reach from there. And earnestly: How many newly registered users do you think will immediately jump to join the OSMF?

This interview I really liked to read – especially I like the remarks on armchair mapping.

bot user accounts 3 months ago

Nakaner: Thank you. It seems "http://" got lost

bot user accounts 3 months ago

PS:
New users with edits you can find here.
Really /all/ OSM data with all users who have ever edited you will find in the full history planet. This does not include user accounts who have never mapped.

Hi oini,

Every user gets assigned an user ID which remains the same even if he changes the user name. The API shows you some details if you ask for them: https://api.openstreetmap.org/api/0.6/user/39504
This page tells you the recent total number of create OSM user accounts: yesterday there were 2340247. But the number of user accounts doesn't correlate exactly with user IDs because now and then swathes of users got already deleted.
However, with a little trial and error I figured out which user registered at the time span I wanted to look at. Then I asked the API to deliver the user details for a certain range of numbers beginning with 3362504: (run on a bash in Linux)

for i in $(seq 2504 8504); do wget https://api.openstreetmap.org/api/0.6/user/336"$i"; done

The result you find in the zip file. I got 5130 newly registered user accounts from November 5th to 7th. Then I looked for "2015-11-07T" in the files and got all users from November 7th which existed until then.
My original purpose for looking at new user accounts was not to look for spam users but they were so obvious I had to talk about them.

What's your OpenStreetMap story? 4 months ago

A little late, but better late than never. ;)

I got to know OSM this way: In 2007 I went by bicycle to Paris. To have the journey in maps on the internet I spend days clicking around at Google Maps which were limited to 24 waypoints (A-Z). As I planned my trip for 2008 (cycling to Istanbul) I looked for easier ways to diplay the travelled way and found GPS-Loggers suitable for me. And while I read about them trying to find out which one would fit best somewhere I read about OpenStreetMap. Regrettably I don't remember more details.

What I remember very well was my first edit. After clicking "edit" flash stuff was loading. I clicked somewhere and suddenly was dragging around a line with the mouse pointer. Clicking around I couldn't get rid of the line, not to mention enhance the map. So I crossed my fingers and closed the tab hoping I hadn't made too much damage. Looking for a better editing tool I found JOSM and am stuck with it since.

Back then my region was quite bare so before starting my trip to Istanbul I already had mapped some highways in my town.

Now, about eight years later, I have made more then 10.000 edits, amongst them a bunch for HOT, filed ~170 bugs against JOSM (most of them are solved) and a lot of other OSM tools, helped translating JOSM, iD, osm.org, set up an OSM affiliate account for amazon.de which generates meanwhile a nice monthly venue for OSM and now and then organised an OSM booth at some Linux and Outdoor gatherings. Once I even lectured about holidays with OpenStreetMap :).

Tent with lake and Mountains I still love to travel remote regions and OSM is a very useful help. I use it and its tools to prepare the journey, while travelling and back home I add a lot of data collected while being abroad.

But lately it seems there are more mappers using dubious map sources (to be euphemistic), don't name their sources and lack a lot in communication. Finding this out and warding it off consumes quite some energy and time I'd prefer to use for mapping myself "good" data. This takes out quite some of the fun of contributing to OSM.

Data issues in Japan 4 months ago

In 2013 I asked about a cleanup for the similar tidy waterway import on the Japanese ML: https://lists.openstreetmap.org/pipermail/talk-ja/2013-January/007104.html The response was underwhelming.

Missing Maps Mapathon Edinburgh, episode 2 12 months ago

For armchair mapping:

I am convinced that mapping from remote is useful and that a lot of persons with good common knowledge can do it with good results after a basic explanation with some examples with hopefully some on-the-ground photos.
For example one could explain: Big highways (primary or trunk) connect big cities, smaller highways (secondary, tertiary) connect smaller ones and between a lot of residential houses highway=residential is mostly appropriate. It doesn't matter if the surface is paved or not.

Even if the imagery is quite old it is unlikely that (major) highways disappear or inhabited places vanish completely.

Not sure what task(s) you worked at, but for example in ebola regions the organisations first hand needed to know where the people lived and how to get there. If you map all the houses (or the residential area) and the ways connecting them better guesses or even calculations can be made. It doesn't matter if you overlooked a dozen houses in a town or accidentially chose the wrong category of highway – the settlement and the street is there and thanks to you the people can be helped.
