[R-sig-Geo] ArcGIS File Geodatabase Format

[Richard Barnes]

I've just released C++ source code at 
https://github.com/r-barnes/ArcRasterRescue for extracting raster data 
from the ArcGIS File Geodatabase (gdb) format.

Additional work, as outlined in the README.md file, needs to be done to 
extend the kinds of compression the code handles, deal with issues of 
endianness (the code has only been tested on a little endian system), 
and better extract geotransforms and CRSs, but the program is serviceable.

I've got what I need out of this, so I don't anticipate putting too much 
more active development into the program myself, but wanted to make the 
community aware of it in case there are others who can benefit from it.

Best regards,
Richard
