Combined Agua Dulce, Acton, Pacifico Mountain, Sunland, Condor Peak, Chilao Flat, Burbank, Pasadena & Mount Wilson Quads in 3D shaded relief type mapClick on Image for Full View

I found some really cool shaded relief type maps using free data from the USGS. To view these maps you need to download the data and viewer. I have compressed all the data for Sunland, Burbank, Condor Peak, Pasadena, Chilao Flat and Mt Wilson Quad's into 1 zip file this data is avalable via anonymous ftp at ftp://24.30.125.185.

 

The file name for the data is San Gabriel mountains.zip, you must install this data into seperate directories hence all the quad's are in seperate zip files. This is required because many of the files have the same names and the viewer won't work if you load all the files into the same directory.

The viewer is in a file named dlgv32-3_6.exe download and install this program, after starting the program and opening one of the datasets select File, Open into current, for the additional datasets. This will create a 3D-relief map view of the supplied quads.

to obtain additional data http://edcftp.cr.usgs.gov/pub/data/DEM/7.5min/
