Editing features with the modify interaction.
This example demonstrates how the modify and select interactions can be used together. Zoom in to an area of interest and select a feature for editing. Then drag points around to modify the feature. You can preserve topology by selecting multiple features before editing (Shift
+click to select multiple features).
