Hello, I am looking for a way to generate a precision code for GPS coordinates of parcel fabric. Is there any way to generate a code for the accuracy of coordinates like a range of number for example 1-7 where 1 signifies most accurate while 7 signifies least accurate.. I am re projecting my data from to LL84. Any suggestion?
I don't have an exact answer for this one, but I think this post from Mark on coordinate system accuracy might be a good starting resource! Hope that helps a little
What is the criteria for the different precision codes, i.e. how to determine if the precision is "1" or "7"?
I think a key question is do you mean the precision of the GPS or the reprojection from LL84?
If it's the reprojection, then Jovita's answer is a good one.
If it's the GPS, what format of data are you using? Most formats (GPX, NMEA, etc) already have precision values and the number of satellites (for example) recorded in their data. It would depend on whether your GPS receiver recorded that information or not. If you can let us know the format - and even provide a sample of data - we might be able to help a little better.

I referred back to Jovita's answer. It was relevant to what i was looking for. Thanks.
