The advantage of using a Postgis, or MySQL (or Oracle) is that you can
then store position data from xastir and retrieve it with another GIS
application that has GIS database support, such as OpenJump or QGIS or
Grass, or in the case of APRSWorld, vice versa, allowing xastir
to serve as a visualization client on top of an APRSWorld database.

It should be very straightforward to extend the existing GIS database
support to a sqlite database engine, the code is structured with a
database agnostic layer that allows arbitrary underlying GIS
databases, with current implementations for MySQL and Postgis.  There
should be reasonable documentation in db_gis.c
