Hi Leela, > Description of problem: I am trying to display 30 arc second elevation data > from USGS. > From what I undersatnd, this is DEM data which is an accepted format for IDV. > However, when I try to plot this data I get the following error message: > > Reading DEM: C:\Documents and Settings\watson.leela\Desktop\w140n40.tar.gz > Data object "C:\Documents and Settings\watson.leela\Desktop\w140n40.tar.gz" > not compatible with "dem" data family > > Note: I have tried unzipping and untarring the file with the same result. > The USGS has a number of DEM formats and the IDV does not read all of them.
