Recently I was asked to look at a map that was created in an ESRI format, but I cannot seem to open it. The folder that I was given has .shp, .shx, .sbx, .dbf, etc, file formats. I downloaded the ArcGIS explorer, but all that I seem to be able to do is to open the .shp files ("Add Content"), and then all I see is a bunch of lines on a white background. I don't want to edit the files, just to view them. Is there a viewer that will allow me to do this? What am I doing wrong?
