DRG files in the Concrete 1° by 2° quadrangle


Click on the map or text for most 1:24K (7.5-minute) quads. Click on the text for other quads.
Note: 15 years after the patent on LZW compression expired, we are converting our uncompressed tif files to internally compressed tif files. This obviates the need to zip them to save space. Losslessly-compressed quad files run about 3 megabytes, while the "f" files are larger and the "z" files are huge.
The old zip files also contained tfw files, which you are unlikely to need. If you want them, they are preserved here.
