[Xastir] GeoPDF try

Mon Dec 14 11:34:29 EST 2015

First go here: http://nationalmap.gov/ustopo/index.html

Then select "Download Maps (map store)"

For now leave the map selection at '7.5 and 15 minute', and leave the
bullet selection to "Navigate".  Zoom in and drag the US map to your
desired location.  When you zoom in far enough, you will see a rectangular
grid; each rectangle represents a separate map.  At that point you should
be able to see which maps you want.  Change the bullet selection to "Mark
Points".  Click anywhere inside a rectangle to create a red marker for that
map.  Then click the red marker itself, which will pull up a list of maps
to download.  Generally you will want to download the first map (top of the
list).

So far I have only downloaded 7.5 minute maps, but I may try some of the
other larger maps and have Xastir use those at higher zoom levels.
