Roderick-
In general, the IDV supports shapefiles with lat/lon values or a limited
number of projections. For the prj file to be read, it should be in a
zip file with the shp, idx, and other files. If just have the files on
disk, try zipping them up together in one file.
Even so, I suspect the shapes will be slightly off unless all the
parameters in the PARAMETER section define the texas state plane completely.

All,
I am attempting to overlay some data on maps produced by our regional mapping
authority. When I open the files in IDV I only have a line.
How do I get IDV to recognize this file, if possible?
I have been working with the projection setting but nothing has worked. I am
assuming this projection is not one IDV can ingest.

The maps are shapefiles. Here is the info from the .prj file
