-------- Original Message -------- Subject: GIS location number on USGS maps Date: Mon, 20 Sep 2004 11:35:36 -0700 From: Kollen, Chris <[log in to unmask]> To: [log in to unmask] Hi: A friend of mine at another library wrote asking for help answering the following question: I have a couple of students who are looking for a USGS quadrangle map online that shows the GIS location number. They have a photocopy of a map of a contiguous area with the location number 8H18264, but they need the map immediately southwest of that quad. Do you know where we might get this? I have tried numerous sections of the USGS site, and some other sites, but to no avail. I've never heard of a GIS location number. Can anyone help me out?
