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.

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.
