What is the difference between the Define Projection Wizard tools and the Project Wizard tools found in the Projections Toolset in ArcToolbox?
In ArcToolbox, located in the Data Management tools are a collection of Projection Tools. These tools define a geodataset’s coordinate system information if it is missing, modify a geodataset’s existing coordinate system information, and convert a geodataset from one coordinate system into a different coordinate system. In order to reproject a geodataset, the geodataset must have a projection defined. You can use ArcToolbox to define a geodataset’s projection. The Define Projection Wizard tool and Desktop Define Projection Wizard tool are used to define a geodataset’s coordinate system information if it is missing, or modify a geodataset’s existing coordinate system information. The Define Projection Wizard tool is used for coverages, grids, and TINs. The Desktop Define Projection Wizard tool is used for shapefiles and geodatabase (feature classes and feature datasets). The Desktop Project Wizard tool and Project Wizard tool are used to convert a geodataset from one coordinate system i
