Triangulations: March 27
- Jeff Thurston’s contribution to the debate over free geodata looks at the question of scale: if you want geospatial data to be free and updated regularly, consider the huge amount of territory that has to be mapped.

- Glenn Letham is wondering whether he should flip the switch and move to another blog he’s got on another service — Anything Geospatial.
- A pro-Iranian-government web site has a review of Cyrus Alai’s General Maps of Persia, 1477-1925 (see previous entry).
- A tutorial on how to make GPS-enabled trail maps using a handheld GPS unit and Topofusion. Via MAKE: Blog.
