No matter what method, A spatial reference is the georeferencing and coordinate system assigned to any geographic data, including raster datasets, raster catalogs, and mosaic datasets. The feature classes have class extensions and relationship classes defined on them, so the behaviour of creating new feature classes for the reprojection result that the standard projection geoprocessing tool exhibits is very cumbersome (class extensions and relationships are lost). If the units of the coordinate variables specified as the x- and y-dimensions are the units of longitude and latitude, respectively, then the data is in a geographic coordinate Coordinate systems, map projections, and transformations.
