Thank Tom,
I'll be sure to check Xastir out.

Post by Mike GoldweberHi Mike,
I don't know Xastir, so I don't know for certain if this advice will be
helpful. However, I am an EC in ARES for my town. I was able to get in
touch with the GIS professional for my town and through him I was able to
get shape files (filled with vector data) of the town. Related to this,
in my last job, I was handling the creation of maps for our software and I
frequently was in touch with town, county, and university personnel to get
map (vector and raster) data. In each case, I requested shape files,
because it was compatible with the software we were using. The shape
files do not require an internet connection. Just disk space and a
program that will read them.
If your program doesn't use shape files, you may be able to use an editor
that will convert the shape file into a jpeg (or gif/bmp/ stc), and that
can attach a lat/lon to different points on the map. This is a good
technique to use for inserting a overhead/aerial photograph into your map
display. I found a base aerial photograph with map data layered on top of
the photo is very exciting.
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
layers later.
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
days.

I'm putting together an APRS project for our county EOC .
I need everything to reside on the computer. No internet access.
I want to use some good quality of our county and surrounding
jurisdictions.
We have an event coming up that will have several dignitaries from other
jurisdictions and agencies present.
I want to do this right.
