What is a non-spatial table?
Nonspatial tables contain only attribute data (no feature geometry) and display in ArcCatalog with the table icon . They exist in a geodatabase as standalone tables, and they can be associated with other tables or feature classes.
What is non-spatial data with example?
Non-spatial data (also called attribute or characteristic data) is that information which is independent of all geometric considerations. For example, a person’s height, mass, and age are non-spatial data because they are independent of the person’s location.
How to create spatial data from a table?
For example, if you have a table or text file containing spatial positions and attributes, you can create a layer or new feature class from the data in the table. If you have a table of x,y coordinates, such as GPS measurements, you can add it to ArcMap to create a new point layer (known as an x,y event layer).
How are non-spatial tabular data related in ArcMap?
In ArcMap, a 1:M or M:M relationship is commonly connected by creating a relate between the feature layer and the tabular data. However, it is possible to join non-spatial tabular data and a feature layer in a one-to-many relationship using the Make Query Table tool.
How to set aspects of the spatial reference?
To set aspects of the spatial reference, such as the x,y-, z-, or m-domain, resolution, or tolerance, use the Environments dialog box. If a spatial reference is not provided, the output will have an undefined spatial reference. The spatial reference of the Template Feature Class has no effect on the output spatial reference.
How to make a spatial reference in gdb?
Reference a feature class or feature dataset whose spatial reference you want to apply, such as C:/workspace/myproject.gdb/landuse/grassland. Define a spatial reference object prior to using this tool, such as sr = arcpy.SpatialReference (“C:/data/Africa/Carthage.prj”), which you then use as the spatial reference parameter.
