[OSM-newbies] Mapping a Technology Institute campus

[Chris Hunter]

Here's a timeline based on what I learned from the first of the Atlanta, GA,
USA mapping parties (prep work for SOTM '10).
Warning: contains shameless plugs.

Week before the event:


   1. Use JOSM to compare the existing map data against the aerial imagery.
   2. If the imagery is high enough resolution, identify and tag as many
   landmarks as practical (buildings, parking lots, etc...)
   3. Divide the campus out into to whatever size chunks make sense to you
   and make sure there's at least 1 GPSr available per chunk.
   4. If possible, start assigning chunks to people as they sign up for the
   event. Try for groups of 2-4 mappers.
   5. Make sure you have access to a flatbed scanner.


Day before the event:

   1. Go to http://walking-papers.org/ and print hard copy reference maps of
   each chunk at various zoom levels.  Make sure to leave some overlap between
   printouts. Mark each printout with whatever chunk it applies to.
   2. Install JOSM, GPSBabel, Yahoo Imagery fix for JOSM, etc... on each
   workstation that will be used after the walking portion of the event.
   3. Install whatever JOSM plugins you feel are appropriate. (walking
   papers, buildings tool, WMS, usertools, etc...)


Start of the event:

   1. Pass out pens, walking papers and GPSrs to each mapping group.
   2. Make sure each group knows how to use the Average function in the
   GPSr.
   3. Have each group use the walking papers to sketch / write down their
   observations.  Whenever practical, shoot a waypoint next to anything
   interesting and mark the waypoint number on the walking papers (saves time
   trying to name the waypoint in the GPSr memory).  Alternatively, use
   netbooks with the LiveGPS and Surveyor plugins)

After finishing the groundwork portion of the event:

   1. Have one person collect and start scanning all of the walking papers.
   2. Have each group use GPSBabel to generate 2 GPX files from their
   GPSrs.
   1. File 1 should be only the waypoints without any tracks.  - Each mapper
      in each group will need a copy of this file.
      2. File 2 should be the tracks without any waypoints. - Upload this
      file to the OSM servers as a public trace.
      3. (NOTE: This was a workaround for a JOSM bug that kept waypoints
      from importing if the GPX file had tracks in it).
      3. Pass the paperwork back to each group.  Open the waypoints GPX in
   JOSM, and download the OSM data for the area.
   4. Use the walking-papers plugin to download the scanned paperwork as a
   rectified image in JOSM.  (Note: there's a bug in the walking-papers plugin
   that will freeze JOSM if you download the walking-papers imagery before the
   OSM data.)
   5. Start Mapping.

Hope this helps,
DiverCTH (Chris)
