Data Frame Issue: No Spatial Reference

Question

Hello,

I am working with several layers in ArcMap 10 that were exported into shapefiles from Transcad that had to be projected and given a coordinate system. Every layer now lines up properly but I cannot use the ruler or import a basemap because the data frame still lacks a spatial reference. When I look at the properties for each layer in the table of contents, they all have the same projection, GCS, and linear units:

Projected Coordinate System: NAD_1983_Texas_Statewide_Mapping_System
Projection: Lambert_Conformal_Conic
False_Easting: 1000000.00000000
False_Northing: 1000000.00000000
Central_Meridian: -100.00000000
Standard_Parallel_1: 27.41666667
Standard_Parallel_2: 34.91666667
Latitude_Of_Origin: 31.16666667
Linear Unit:  Meter

Geographic Coordinate System: GCS_North_American_1983
Datum:  D_North_American_1983
Prime Meridian:  Greenwich
Angular Unit:  Degree

I have tried reprojecting these layers but this has not resolved the problem. Anybody know what I can do to fix this?

Thank you! This solved the problem. I did not think to check under Data Frame Properties.

Hi Micah

As i can read, you checked that every layer in your TOC has it's spatial reference correct, but in ArcMap you can define the Data Frame's Spatial Reference through Data Frame Properties, all you have to do is check Data Frame's Coordinate System and (if it's Unknown) set it to NAD_1983_Texas_Statewide_Mapping_System. Have you checked it?

Greetings
