----------------------------Original message---------------------------- A couple of points may be a problem: a. possible that the CD you got Arcview1 off of has a defective copy of the software? try another cd, or go into www.esri.com and download a copy of the software. Jason Simpson (systems manager here) pulled drg with lancaster CA on, called up arcview and a topo from that cd and it worked fine. b. next catch - you need to have right hardware, enough RAM, etc. - step a. above was done on a pentium with 32MB RAM. c. any image software that will read tiff should be able to handle the drgs - e.g., photoshop does.
