i have a shp file map on a lambert conformal projection and i want to convert it to a standard la lon map using the Data Management/Projections and Transformation/Feature/Project tool. however i cannot figure out what projection represents the lat lon?
You have to identify geographic coordinate system of your data first. Go to feature class properties and in XY Coordinate System tab you will find this information. Here's an example: [ATTACH=CONFIG]16117[/ATTACH]
Identified geographic coordinate system can be found in: Coordinate Systems/Geographic Coordinate Systems folder. for example: WGS 1984 is in World subfolder, NAD 1983 is in North America subfolder.
