Coordinate systems in Arc 10.1

RadekM

Hi!
Could anyone help me with finding location of a folder that contains geographic and projected coordinate systems in ArcGIS 10.1? i would like to add some coordinate systems but i cannot find folder with .prj files.

Hello,

If you already have a .prj file, add it to your Favorites location:

On XP,

C:\Documents and Settings\login\Application Data\ESRI\Desktop10.1\ArcMap\Coordinate Systems

On Win7:

C:\Users\login\AppData\Roaming\ESRI\Desktop10.1\ArcMap\ Coordinate Systems

If you want to create a new coordinate system, click the globe icon at top right (to the left of the star icon). To modify an existing coordinate system, right click it in the directory listing and choose "Copy and Modify".

If you want to modify a .prj file in Notepad or some other editing tool, you'll have to add it to Favorites first which will write the definition to a file.
