Select by selection

Select by Selection defines a new selection in a new layer based on the current selection. This includes features that intersect, are bounded by, cross, and are contained in current selection or a buffered area.

Step 01> Start by creating a new selection using either the Selection Panel or Search Panel.

PLEASE NOTE: in this case, a single Flood Zone polygon is selected which will be used to select House's that fall within the flood zone.

Step 02> When at least one feature is selected, click the Select by Selection button on the Selection Panel.

An option is available to choose the layer, if features from multiple layers are selected.

Step 03> From the Select features in drop-down list, choose the layer that features will be selected from

Step 04> Insert a spatial operator into the That drop-down list.

See here for more details on how spatial operators work.

Step 05> Then choose the layer containing the selection from The selected features in drop-down list.

Step 06> Type an integer into the With buffer distance of field. This is optional and will buffer the selected features and use the buffer to make the new selection.

Step 07> Click OK to start the selection process.

Step 08> The new selection is made.

The example shows Address No's that are contained by the selected Flood Zone polygon.

 

See the selection mode section to find out how to manipulate the current selection.
