[Xastir] Xastir Digest, Vol 49, Issue 7

[Guy Story KC5GOI]

Jess, I have been wrestling with Tiger maps this weekend myself and Lee
helped me on my dbfawk issue.  I noticed clarity issues too but I did some
playing around with map selection.  I originally selected the folder for my
desired county and I think this is a "too much information" issue on the
mapping.  Here is what I found when I was playing with my county's files.

arealm - has things like city parks
areawater - lakes, ponds, etc
cousub and cousub00 - borders but I am not exactly sure what they are
borders to
edges - gave me streets with names
pointlm - buildings like schools.  I had indicators on the map that did not
have names.
tabblock - map shading.

I do have some files that are getting complaints in the shell I started
xastir from.  tabblock00, bg00 (restored it due to different complaint),
taz00, tract00 and vtd00.  I renamed them and did not see any reduction in
functionality with the maps.  The complaints were about missing dbfawk files
but I suspect they are not required so the files do not even need to exist.
For example tabblock00 had a complaint were tabblock did not.

I selected just edges and tabblock and I like the maps I have.  Someone will
correct me if I am wrong but I believe the dbfawk file has the zoom level
settings that controls when names are displayed.

The dbfawk files for the 2008 maps did not help me out on the 2009 maps.
That is not a huge loss to me right now.  Since I am on Ubuntu 9.10 and used
the repository for my install I am limited.  That is price for not rolling
my own install.

I am on digest mode so if someone makes corrections to my post, I will see
them tomorrow.
