I need coordinates transformation for Point Feature Clases. Situation:
I have imported points in local projected coordinate system. Now I need to get points coordinates in geographic coodinate system. I need to have each point coordinates in attribute table. So, in attribute table I use calculate geometry function. It seems that after I calculate coodinates to geographic system (DMS), seconds parts become incorrect. Is it possible that an error accurs while making a transformation? Does anyone has any other comment on this question?
Coordinates example:
Local system: 6207549.78, 318656.45
WGS system after transformation: 21°5'41,58"E 55°58'4,13"N
Result using different calculator: 21°5'41,64"E 55°58'4,08"N
I can't remember the author, but in a Geography text book I once read:
" A map is a set of errors that have been agreed upon"
Had it hanging in my cube for years. Couldn't find the source in a google search, but this has pretty good description:
