[Shake-dev] shakemap topography

[Bruce Worden]

The problem seems to be that your map's dimensions exceed the range of the file. The map goes from 1.55 to 4.05 degrees longitude, but the file's maximum longitude is 3.85 degrees.

You'll need to 1) reduce the size of the map, or 2) shift the map so that the right edge is 3.85 degrees or less, or 3) increase the size of your topo file.

Hope this helps,
Bruce
