Eric, et. al. Should I also assume that I can create a state plane, nad27, meters by adding TMMISOCM,tranmerc,1.0 ,20925832.16 ,0.0822718542249391,294.9786982 ,1 to the project.dat file?
So far, I have the following in tranmerc.dat: TMMISOCF,0.0 ,500000.0 ,0.999933333 ,-1.614429558094754 ,0.625409648049525 ,20925832.16 ,0.0822718542249391,294.9786982 ,1 TMMISOCM83,0,500000,0.999933333,-1.614429558,0.625409648,20925391.87,0.08181 9191,298.2572221,1, and the following in project.dat: TMMISOCF,tranmerc,0.30480061 ,20925832.16 ,0.0822718542249391,294.9786982 ,1 TMMISOCF83,tranmerc,0.30480061 ,20925391.87 ,0.0818191910429546,298.2572221 ,1 TMMISOCM,tranmerc,1.0 ,20925832.16 ,0.0822718542249391,294.9786982 ,1 TMMISOCM83,tranmerc,1.0 ,20925391.87 ,0.0818191910429546,298.2572221 ,1 It appears to me that I'm missing something . . . but I'm not quite sure how to fix it. Is this complete? Or might there be something else to add/ammend?

Please try selecting another output datum and/or >projection. There is no projection defined for Missouri Central NAD83 meters, only one for feet. To add this to ER Mapper's projection database: 1) Close ER Mapper. 2) Add this line to the tranmerc.dat file in ER Mapper's GDT_DATA directory: TMMISOCM83,0,500000,0.999933333,-1.614429558,0.625409648,20925391.87,0.08181 9191,298.2572221,1, 3) Add this line to project.dat (also in GDT_DATA): TMMISOCM83,tranmerc,1.0 ,20925391.87 ,0.0818191910429546,298.2572221 ,1 4) Restart ER Mapper, assign that new projection to your dataset (using the Dataset Header Editor), then run the reprojection to UTM15.
