Dear ArcGIS users,
I have one shapefile with point which I dowloaded from GPS and it is in WGS84 coordinate system. Now I'm trying to change/transform coordinate system to Bessel1841(also I need to add additional parameters for my area). For this transformation I'm trying to use Project tool from ArcToolbox, but I get message "Undefined geographic transformation". Can you, please, tell me what is problem and is there any other way to change/transform coordinate system?
Thanks in adance,
