What is a spatial index file?

ArcGIS uses spatial indexes to improve spatial query performance on feature classes. When you create an empty feature class* or import data to create a feature class in a geodatabase from ArcGIS, a spatial index is created on the feature class. The spatial index is used when querying and editing data.

What is the spatial index in ArcGIS?

The spatial index is defined by using a grid-based system that spans the extent of the features in a feature class, like a locator grid you might find on a common road map. By default, ArcGIS creates and maintains a spatial index for geodatabase feature classes.

What is spatial index in mysql?

SPATIAL INDEX creates an R-tree index. For storage engines that support nonspatial indexing of spatial columns, the engine creates a B-tree index. A B-tree index on spatial values is useful for exact-value lookups, but not for range scans.

How do I modify the spatial index in ArcMap?

Start ArcMap and open the Catalog window or start ArcCatalog. In the Catalog tree, connect to the geodatabase or database that contains the feature class for which you want to modify the spatial index. For enterprise geodatabases or databases, connect as the data owner to rebuild indexes. Right-click the feature class and click Properties.

What is a spatial index grid?

Personal geodatabase feature classes receive a spatial index grid size based on the spatial reference properties of the feature class. This index grid cannot be overridden, removed, or modified. Spatial Grid 1 is the first, or lowest, grid level and has the smallest cell size.

How do I remove a spatial index from a geodatabase?

For a geodatabase feature class to not have a spatial index, you must explicitly remove it using the Remove_Spatial_Index tool. The Spatial Grid 1, 2, and 3 parameters only apply to file geodatabases and certain ArcSDE geodatabase feature classes (those that use SQL Server binary storage, DB2, Oracle binary storage, or Oracle ST_Geometry).
