General Considerations

If you haven't seen them already, be aware of the specific recommendations for the U.S. and California.

Perhaps the one thing most needed is the cleanup of imported TIGER data. Common problems found with San Diego TIGER data include:

  • Roads mapped as intersecting where in fact one road passes above or below another
  • Roads mapped as intersecting where one road actually stops short of another
  • Divided roads mapped as a single road, with some cross streets shown as allowing cross traffic when in fact they do not
  • Entire roads mapped that don't exist in real life
  • Roads that change names along their length do so in the wrong place

Most other imported data (addresses, building outlines, bus stops) is from SanGIS.

Suburbs, Villages, Hamlets, (Quarters, Neighbourhoods)

Hello, I'm stevea, an OSM volunteer since 2009, I grew up in San Diego and graduated from Patrick Henry High School. I have been "adjusting" the place=* tags around the City of San Diego based upon the Community Profiles shown at the City's web site. Harmonizing these roughly equates to "area" or "community" being a place=suburb node and "neighborhood" being a place=village or place=hamlet node, depending on population (> or < 10,000 or so) and geographic size. This method by which the City characterizes our communities, and given this particular tag-mapping, OSM's additional tags of place=quarter and place=neighbourhood do not map well semantically, so these tags are not used locally. Because of the relatively slow rendering process (hours or days, not minutes) of the wider zoom levels displayed by the Carto (Standard) layer, getting this tagging right and seeing its feedback continues. Thank you for your patience; I believe San Diego will both return Nominatim search results as well as render very nicely after this harmonization is complete.

Mapping Parties!

Mapping parties are community events targeted at getting a specific area mapped in a day or a weekend. You come along, are loaned a GPS unit and shown how to use it (it's easy!) and you go out mapping an area of your choosing. Then you come back and are shown how to get that data in to the map.

They are relaxed events and you're supposed to have fun. Often we grab a beer after the event.

No San Diego mapping parties are planned at this time.
