How is the spatial reference system used in ArcGIS?
See How the spatial reference system is used in ArcGIS in this topic for more information. When created through ArcGIS, a spatial reference system with a specific SRID is assigned to the feature class. If a spatial reference is not assigned, the feature class has an unknown spatial reference.
What does spatial reference mean in enterprise geodatabase?
Spatial references include a coordinate system for x-, y-, and z-values. In enterprise geodatabases, the spatial reference also includes tolerance and resolution values. All this information together helps indicate where on the earth the shapes on your flat map represent.
Where can I find the describe spatialreference property?
A SpatialReference object can also be accessed from existing datasets using the Describe spatialReference property. Which spatial reference properties are available depends on the coordinate system used.
Can a table have more than one srid in ArcGIS?
Spatial references. When spatial tables are created directly in the database (outside of ArcGIS), each record in a spatial table can be assigned a different SRID and spatial reference. However, when you use these database tables with ArcGIS, ArcGIS only recognizes one SRID and spatial reference for the whole table.
Where are data layers stored in ArcGIS platform?
Different types of layers can access and display different types of data. The data for a data layer is typically stored in the ArcGIS Platform as a data service. You can use feature services, vector tile services, and image tile services to host your data. Learn more in Data hosting.
How are spatial references stored in a geodatabase?
Spatial references. In geodatabases, your spatial data is stored in separate feature classes and raster datasets based on the type of spatial data it represents. For example, roads are stored in one feature class, parcels in another, and buildings in a third.
