Using NAD 83 SP coordinates, version 2.05. In the raw data print out, the geodetic coordinates do not match the decimal feet coordinates using corpscon to convert between the 2. I thought I understood the information in the raw data file, but now I'm not sure. Is there a detailed explanation of the raw data file?

If you are refering to this type of raw data record:

I think this is the data format.
The LA35.225288576599 is 35° 22' 52.88576599"
The LN-119.035486722387 is 119° 03' 54.86722387"

The CorpsCon conversion to CA Zone 5 NAD83 resulted in the coordinates shown in the raw data line that I have highlited.

See if this works with your data.

The raw data looks different to me. I have attached a screen capture of some of my data. This is an example of where I have had the problem. I am using Illinois East zone NAD 83 data.

thanks for the input.

I hate being such a dumb ass. The problem is my operating corpscon.
Problem solved.

Thanks Ken
