3.11.2 Determining the N-Nearest Geometries
Using the
SDO_NN_V2
filter, you can determine the N-nearest
geometries to a geometry.
Note:
TheSDO_NN_V2
filter, introduced in Spatial Studio release 22.2, is an improved form of the
SDO_NN
filter which was used in the prior releases of Oracle Spatial Studio. The old behavior will
continue to be supported when you modify analyses that were created using the
SDO_NN
filter. However, when creating a new analysis, the
current SDO_NN_V2
filter will be used.
To find the N-nearest geometries, you must perform the following
steps.
The instructions assume that you have the layer to be filtered and the
map layer to be used as a filter displayed on your Active Project page.
