KB10163 - How can I define U.S. State Plane coordinate systems in the AIC? For instance, I need to reproject some scanned maps that are in UTM meters into the Texas North Central (in feet) coordinate system?

The AIC supports all of the U.S. State Planes, i.e., it supports the projections and datums required to define each State Plane coordinate system. If you need to know the parameters to define a specific State Plane, refer to: http://www.ngs.noaa.gov/PUBS_LIB/ManualNOSNGS5.pdf.

In this case it appears that you are referring to the "Texas FIPS 4202" U.S. State Plane coordinate system, which can be defined in the Projection panel (of the Projection Manager module, given that you want to project the output image to this coordinate space) as follows:

Datum=NORTH AMERICAN 1983, CONUS
Lambert_Conformal_Conic
False_Easting=1968500
False_Northing=6561666.666666666
Central_Meridian=-98.5
Latitude_Of_Origin=31.66666666666667
Standard_Parallel_1=32.13333333333333
Standard_Parallel_2=33.96666666666667

A post 2.0 AIC upgrade version will add for the selection of each of the U.S. State Planes (and most map grid coordinate systems in use around the world) from a drop down list. This will eliminate the need to manually enter the parameters to define a State Plane or other map grid coordinate system.
