Xastir definitely handles shapefiles. It can be a little bit of a challenge
to construct the file required to get it to render those shapefiles in a
pretty way, but there is a powerful capability to do it (through its "dbfawk"
system). The system allows one to select shapes from the shapefile based on
attributes, level of detail appropriate to the zoom level, label the shapes
using combinations of attributes, and so forth.
Using local GIS departments to obtain shapefile data is an excellent approach,
especially for emergency operations.
Xastir will alow you to overlay shapefiles over any raster layer you like,
including locally stored USGS topo sheets, FAA sectional charts, georeferenced
scanned images, as well as on-line map layers (e.g. openstreetmaps,
terraserver aerial photos, etc.).
And APRS tracks from xastir can be exported as shapefiles to be used for
documentation purposes, for import into other programs, or to use as map
Under normal circumstances the best place to talk about using Xastir is on
the Xastir mailing list, but the list and the Xastir wiki are both in the
middle of being moved from one server (where they have lived for years) to
another, and both are currently down. I have it on good authority that the
list is expected to be returned to operation first, and within the next few
