-------- Original Message -------- Subject: Fwd: GIS for state geologic indexes? Date: Wed, 13 Feb 2008 10:23:30 -0500 From: Jeff Essic <[log in to unmask]> To: [log in to unmask] Ken, If you now have ArcGIS, you should also have access to ESRI Data and Maps DVDs. In the usa/other folder, there are index files for 1:250K, 1:100K, and 1:24K scales. See http://www.lib.ncsu.edu/gis/search/search.php?q=quadrangle&rk=1&s=ds <http://www.lib.ncsu.edu/gis/search/search.php?q=quadrangle&rk=1&s=ds> for more info about these layers. The NC Geologic Survey did something like what you are describing several years ago at http://www.geology.enr.state.nc.us/maps/24k_index_page.html Best Regards, Jeff Essic __________________________________________________ Jeff Essic, Geospatial Data Services Librarian North Carolina State University D.H.

This seems like the kind of application that someone would already have done (for another state if not for mine), so I wonder if anyone can provide me with some guidance. For one thing, where might I find a file for the grid of Utah topographic quadrangles that can imported into ArcGIS? --Ken Rockwell Univ. of Utah
