What is EPSG code?

EPSG stands for European Petroleum Survey Group and is an organization that maintains a geodetic parameter database with standard codes, the EPSG codes, for coordinate systems, datums, spheroids, units and such alike.

How do you add a spatial reference?

Scroll down to the Spatial Reference section, and click Edit. On the Spatial Reference Properties dialog box, do either of the following: Click Select and choose a predefined coordinate system. Browse to the coordinate system folder, click the one that is required for your raster dataset, then click Add.

What does spatial reference mean in GIS?

A spatial reference is the coordinate system used to store each feature class and raster dataset, as well as other coordinate properties such as the coordinate resolution for x,y coordinates and optional z- and measure(m)-coordinates.

What is WKID?

The Well-Known ID (WKID) is a unique number assigned to a coordinate system. You can find the WKID in the Coordinate Systems Details window. Once you know this number, it’s a handy way to search for the coordinate system later.

How to make a spatial reference in Python?

It is not often practical to keep all details of a spatial reference inside a Python script. By using a projection file, factory code, or spatial reference name as an argument to the SpatialReference class, you can quickly complete the properties of a spatial reference and use the object as input to a geoprocessing tool.

What are the properties of the spatial reference?

The z false origin and units. The z resolution property. The z-tolerance property. The abbreviated name of the spatial reference. The alias of the spatial reference. The extent of the xy domain. The factory code or well-known ID (WKID) of the spatial reference. The false origin and units.

What is the alias of the spatial reference?

The z-tolerance property. The abbreviated name of the spatial reference. The alias of the spatial reference. The extent of the xy domain. The factory code or well-known ID (WKID) of the spatial reference. The false origin and units.

Where can I find a spatialreference object in ArcGIS?

A SpatialReference object can also be accessed from existing datasets using the Describe spatialReference property. XY, Z, and M extents are not the same as spatial reference domains.
