Editing Overview
HydroAdd allows you address existing points and lines in your service to NHDFlowline. Addressing of polygons to NHDWaterbody will be added soon.
The map must be at zoom level 14 to edit a feature.
Open a feature for editing
There are two ways to open a feature for editing:
- Click the Edit button
in the row of a selection or queue, or
- Click directly on the feature in the map with the regular arrow cursor
.

Cursors
HydroAdd has two kinds of cursors: the editing cursor
and the selection cursor
.
- The crosshair cursor
is the editing cursor. It is visible only when a feature is open for editing.
- The map must be at zoom level 14 to edit a feature.
- The regular arrow cursor
is a selection cursor. Use the arrow cursor to select features from your service layer.
- The crosshair follows the arrow cursor, but the crosshair is always snapped to the nearest flowline.
The crosshair cursor can only sit on flowlines.
- Pay attention to where both cursors are when you are editing. It is possible to accidentally select a different feature than you intended!
- Best practice is to keep both the arrow and crosshair cursors slightly apart when editing.
