These standards facilitate the transfer of coordinate system information from one software application to another. EPSG is one of several accepted spatial reference systems used to standardize coordinate system definitions. You'll also note the presence of a WKID number, 26919 and its associated authority, EPSG. Other useful information that cane be extracted from the Spatial Reference properties is the layer's coordinate value's unit (meters in this example). Thinking that the data must lack vertical information read that I can add vertical datum information using the Define Projection tool. However, the raster appears in the wrong place on the map (centered at (0,0)). Using the Define Projection tool, I am able to set the coordinate system without issue. However, I have the correct values for these parameters. I understand the vertical option is only available if and only if the data have vertical datum information. ArcGIS doesnt read the projection or extent correctly due to issues with the input file.
They are in fact stored as in a PCS reference system. This checkbox disappears when I select my input raster.
Analysis Tab -> Tools, search for Define Projection ArcMap: Raster and Vector. In the window that opens make sure that the. So the fact that both a PCS and GCS definition are present in the Spatial Reference properties does not mean that the data layer's coordinates are stored in both a PCS reference system and a GCS reference system. To fix an incorrect spatial reference: ArcGIS Pro: Raster and Vector Data. Then under the Raster menu select Projections and Warp (Reproject). It's important o remember that all PCSs are built off a GCS. The PCS was built off of a GCS North American 1983 geographic coordinate system (GCS). The Spatial Reference block indicates that the Counties layer is defined in a UTM NAD 1983 (zone 19N) projected coordinate system (PCS).
