That looks REALLY nice Lee! For a Christmas present.. could you write
up a doc of the steps to get that fully working? Though the online OSM
work, they are pretty dark and blurry for my tastes. These would be a
major upgrade!

OK, got the conversions working. Some screen shots are available via the
links below:
Screen shot 1 - the geotiff file for Leesburg, VA as displayed in the
ristretto image viewer in Xubuntu 15.04.

Screen shot 2 - the same geotiff file displayed in Xastir. Still a decent
offline map, but it doesn't display the text as clearly.

I'll plan to provide detailed instructions for the following:
- where to download the geoPDF maps
- what Xastir needs in order to support geoTiff maps
- how to install what is required to convert the USGS geoPDF files to
geoTiff files
- how to convert the files with the applicable perl script
- where to put the maps so Xastir can use them
Best,

Without the imagery, you don't need the high DPI that will be used by
default,
and so the thing processes much, much quicker (less than a minute, vs.
more
than 40 minutes). And instead of a 100+MB file, you get a 26MB file.
The result looks very, very nice.
Thanks, Tom, for all the detailed feedback, which is not out of character
:-)
I thought building gdal from source might be required given I had to do
that last time.
Back then I had aspirations of documenting step by step what it took to
convert and use those maps but never got to it. At that time they came out
a little dark but were still very usable. It sounds like the newer
geoPDF's may convert into nicer looking maps. I'm off to try the FTP site
from your other message so I can take a look.
I took a look, and the map does look great. The goal now is to get
conversion working for me and plug them into Xastir. I'll post a link to a
screen shot of Xastir using them when
I have it up and running.
