3.11.1 Determining the Geometries Within a Specified Distance

Using the SDO_WITHIN_DISTANCE filter, you can filter coordinates that are within a specific distance from a point on the map layer.

To filter points based on this proximity filter, 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.

1. Click against the map layer whose coordinates needs to be filtered in the Layers tab.
2. Select Spatial Analysis.
   The Spatial Analysis Operations window opens as shown in Figure 3-79.
3. Click on the Filter tab and select Return shapes within a specific distance of another.
   Within distance dialog box opens as shown:

4. Enter Analysis name.
5. Select the Layer to be filtered.
6. Select the Layer to be used as the filter.
7. Enter distance and unit.
8. Click Run.
   The Analysis result is listed under Analyses in the Data elements panel on the left pane of the Active Project page.
9. Drag and drop the analysis result on the map view.
   This creates a new map layer highlighting the filtered coordinates within a specific distance from a point as shown:
