When do you create a spatial index in ArcSDE?
When an ST_Geometry column is added to a business table, a spatial index on that geometry column is usually created. When ArcSDE creates a feature class with an ST_Geometry column, it creates a spatial index by default. Alternatively, ArcSDE can create feature classes with no spatial index.
How does the spatial grid index work in Excel?
The spatial grid index is two-dimensional and spans a feature class, similar to the reference grid you might find on a common road map. You can assign the spatial grid index one, two, or three grid levels, each with its own distinct cell size. The mandatory first grid level has the smallest cell size.
How to recalculate the grid size in ArcCatalog?
The recalculation of the grid size must be done from the Feature Class properties dialog box in ArcCatalog. This requires the use of the Stop Editing function. Save any edits, and close the Map Document containing the feature class. For steps to recalculate or modify the grid size of a feature class, refer to ArcMap: Rebuild a spatial index.
How is the spatial grid index in DB2 built?
The spatial grid index. Geodatabases in Oracle and DB2 use grid indexes. The spatial index is built by applying a grid to the data in the spatial column. The spatial grid index is two-dimensional and spans a feature class, similar to the reference grid you might find on a common road map.
Where can I find Esri St _ geometry in Oracle?
Using the Esri ST_Geometry spatial type in a geodatabase in Oracle or an Oracle database, you can access your spatial data through SQL functions that implement the ISO SQL/MM Spatial Standard and to the Simple Feature Specification of the OGC.
Can you add a spatial index to an oracle table?
You can add a spatial index to the table prior to registering it with ArcSDE. However, if the table is in an Oracle database, contains an ST_Geometry column, but does not contain any data, do not add a spatial index before registering with ArcSDE.
Can a geodatabase feature not have a spatial index?
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).
