R-tree index

The database server can support the R-tree index for columns that contain spatial data such as maps and diagrams. An R-tree index is most beneficial when queries look for objects that are within other objects or for an object that contains one or more objects.

To use an R-tree index, use the Informix® spatial solution or install a third-party DataBlade module that implements an R-tree index. For more information about R-tree indexes, refer to HCL Informix R-Tree Index User's Guide.
