Is the coordinate system the same in ArcMap?
Same as Display —In ArcMap, ArcScene, or ArcGlobe, the coordinate system of the current display will be used. Same as Layer —All layers are listed, and you can choose one as the coordinate system.
When do I set the output coordinate system?
When the input and output coordinate system require a geographic transformation, set the Geographic Transformations environment. This specifies the output coordinate system of geodatasets created by geoprocessing tools. Same As Input —The output geodataset will have the same coordinate system as the input. This is the default.
When to use the batch define command in ArcGIS?
This command can be used if the input datasets do not have a projection defined. If either of the input datasets has a projection defined, a warning will be raised but the tool will execute successfully. The input datasets can include feature classes, raster datasets, and layers.
When does processing occur in the same coordinate system?
Processing (calculation of geometric relationships and modification of geometries) occurs in the same coordinate system as the output geodataset. This environment overrides the default coordinate system on output geodatasets created by geoprocessing tools.
How to use the same as display in ArcGIS?
Same as Display —In ArcMap, ArcScene, or ArcGlobe, the coordinate system of the current display will be used. Same as Layer —All layers are listed, and you can choose one as the coordinate system. Like the Same as Display option, the coordinate system of the layer is read and stored.
How to choose the coordinate system for output geodatasets?
As Specified Below —Choose the coordinate system for output geodatasets. Specify a coordinate system name or browse using the Spatial Reference Properties dialog box. Same as Display —In ArcMap, ArcScene, or ArcGlobe, the coordinate system of the current display will be used.
How to set the coordinate system of an output?
By default, the coordinate system of an output will be the same as that of the input; otherwise, the Output Coordinate System can be set using any of the following: SpatialReference object A dataset A .prj file
