  Can you tell me about the aerial photography and how I can acquire it?

The 6 inch and 1 foot aerial photography is not hosted by this site. You must contact the Texas Natural Resources Information System (TNRIS) to request the 2010 Aerial photography.

Can I acquire the contours in DXF or DWG format?

Yes you can; however, we do not support Autocad format and do not have technical expertise in Autocad Map. Since the "Z" elevation is an attribute of the ESRI file format, that information is lost when it is converted out to a dxf file. It is recommended that you obtain contours in ESRI based shapefile format and convert them yourself into Autocad format - preserving the z-elevation attribute.
