Getting to know the OSM editors

Posted by KAbhijit on 23 September 2015 in English.

Used this for a couple of months within firefox. Added lots of details / fixes for stuff within IISc. But iD2 is quite slow and starts to lag after a while.

Moving to JOSM now, on a *nix machine just need to download the JAR, then run it using the Java VM installed.

JOSM seems quite easy to use (perhaps since i have used Viking). The web based help is here: https://josm.openstreetmap.de/wiki/Help Need to join the newbies’ mailing list as well.

Theres a couple of things that are not clear to me yet, though: 1. Dealing with multiple entities (shops, offices, etc) within one physical building 2. Defining which road / path / segment should be used to approach the entrance of a building 3. Attaching POIs to bus / train routes etc.

Will update this as i go along.

Should learn how to use Overpass and its API.

  1. I use different nodes in the same building for each POI. So one node per shop and per office. Try to position them as close as possible to the real world position. You could add more detail with indoor mapping tag if you are interested
  2. Draw a path from the street to the door, connect with the building add entrance=yes to the node on the building and path. I’ve seen some people adding operator to the node to indicate to which shop it belongs.
  3. I don’t understand. A bus route should only contain information about the bus route: i.e. stop positions and the road segments it follows. You should not add a shop to a bus route just because the bus passes the shop. Can you explain better what you try to achieve ?

As for the overpass API, there was a Google Code of Summer project were a student developed a platform to learn Overpass: http://osmlab.github.io/learnoverpass

In case you have problems mapping something, http://help.openstreetmap.org is a good place to start looking for answers. You could also try to get in touch with your local community. They might be using a mailing list, forum, Facebook page, IRC, etc. You’re not alone. Don’t be shy to ask questions.

Happy mapping
