Good news is that USGS has just recently released 2013 US Topo maps for virginia in geoPDF format. These contain streets, contour lines, elevation maps (which can be shown as shaded relief), and 1m resolution satellite imagery. There are a couple problems:
– Not enough software support for the extra features and most of that is on windows.
– They make it difficult to get the URLs without lots of manual work.
But you can use:
– Adobe Acroread on linux/Mac OS X/windoze: lets you turn layers on and off but doesn’t measure
– TerraGo toolbar for windoze acroread does measurements
– okular (linux, *bsd, mac os x, windoze,etc.), display but not turn layers on/off, manually extract the embeded xml metadata and the embeded
PDF with the symbol key.
– evince (linux), display but not turn layers on/off
– pdfimage (popplar-utils)- extract the image tiles. Not clear where they go but they seem to follow UTM grid from lower left corner, bottom to top then left to right. These image tiles look really good at 1:1 scale and not rotated (they are rotated to fit the UTM latitude and longitude grid of the map).
– exiftool – doesn’t seem to be able to extract the embedded files but does get very limited metadata.
In the long run, files like this could be used standalone or as data for programs like KDE marble. It appears that they have all the data you need for google earth style earth browser for the limited area they cover and combined with the other files in the area could be a single source that could be used standalone with pdf. I am not sure how the road data is encoded. Also needed is a program that will break a 7.5minute quad into 9 2.5minute quads with the appropriate scales copied, for when you need to print on 8.5×11 paper, join adjacent maps together to make a larger map (trimming off the scales where they join), as well as extract arbitrary map regions from one or more files.
– Imagemagick. Use montage to joint tiles extracted by pdfimage, or use convert to make pdf into a jpg
Note that this convert does not include the satellite imagery.
Raster file will lose its georeferencing.
– pdftoppm will make a raster image out of the file and include the satellite imagery.
pdftoppm VA_Charlottesville_West_20130611_TM_geo.pdf /tmp/test2
– strings -n 16 VA_Charlottesville_East_20130611_TM_geo.pdf | fgrep -i contents
This will dump out a string that appears to contain, among other things the registration info.
– dump the latitude/longitude registration info
strings -n 16 VA_Charlottesville_East_20130611_TM_geo.pdf | fgrep -i contents | sed -e “s@.*/\(Projection/Units (deg)>>/Registration[^/]*\)/Type.*@\1@”
– latitude/longitude sort. Uses a crude truncation instead of rounding to get around fact that registration points are not evenly lined up.
(for i in VA_*.pdf; do echo -n “$i:” ; strings -n 16 $i | fgrep -i contents | sed -e “s@.*/\(Projection/Units (deg)>>/Registration[^/]*\)/Type.*@\1@”; done ) | sed -e “s/\(.*\):.*(\([-.0-9]*\)) (\([-.0-9]*\))\]\]/ \3 \2 \1/” | sed -e “s/\([0-9][0-9].[0-9][0-9]\)[0-9]*/\1/g” | sort -n -k 2 -r | sort -n -k 1 -r
– GDAL, compiled incorrectly on ubuntu, so not working yer

My house is in Charlottesville West. The pdf file contains hundreds of image tiles including scenery, clipping masks for scenery, and elevation maps. These are mostly 1024×1024 and they appear to be aligned with the angled UTM (Universal Transverse Mercator) gridlines which makes about 1meter per pixel resolution. They can be extracted using:
mkdir scratch
pdfimages -j VA_Charlottesville_West_20130611_TM_geo.pdf scratch/img
My house is in img-256 but without the adjoining tile img-258 that includes the intersecting street, it is hard to get bearings. Imagemagick to the r

To just make an image of the whole map, use:
convert -geometry 2400×3150 VA_Charlottesville_West_20130611_TM_geo.pdf VA_Charlottesville_West_20130611_TM_geo.jpg
This was done at roughly 300dpi, may want 600 or 1200. Note that this makes a topo map without the satellite imagery or shaded relief.
