Search/Select

You can search your service layer to make a selection. A selection is a temporary list of features in your service layer. To make a selection permanent, add it to a queue. Features in the selection appear as rows in the selection pane.

• Click a row in a selection to zoom to the feature at level 16. This allows you to inspect the feature before editing it.
• Selected items appear cyan on the map.
• Hover the cursor over a row to highlight features yellow on the map.
• To save a selection, add it to a queue.
• Selections are paginated. You can choose the number of rows per page.

Find a ReachCode

Search by ReachCode does not search your service layer. Rather, HydroAdd searches for ReachCodes in the National Map NHD HR service layer. This function is a convenient way to find ReachCodes.

NOTE: you cannot make a selection from your service layer with ReachCodes. There are very many ReachCodes in the NHD, so this search can take a few minutes.

1. Type a full or partial ReachCode into the search bar.
2. HydroAdd filters ReachCodes based on the entry.
3. Flowlines list in the lower half of Search/Select pane.
4. Flowline features appear cyan on the map.
5. Hover the cursor over a row to highlight the flowline feature yellow on the map.
   

Select Row functions

Click the row to zoom to the feature. Hover the cursor over a row to access the row buttons. Each row has four buttons: Approve, Unapprove, Edit, Add to Queue, and Delete.

Select row Checkbox

Use the Pick All checkbox to pick all rows on a page or use the checkbox in a row to pick single features. Note that the Pick All checkbox only picks rows displayed on a page. For example, if there are 10 rows in the Search/Select pane, only 10 features will be picked. To pick more rows, increase the number of rows per page or go to the next page. Once you have picked multiple rows, you can delete, approve/unapprove, or add to/remove from a queue.

Select row SourceID label

HydroAdd requires a SourceID as a unique identifier for all features in your service. Rows in a selection or queue show the SourceID. You normally assign SourceIDs to features in your service during schema preparation in ArcGIS Pro. If a feature does not a have a SourceID, HydroAdd requires you to enter one to save your edits. Likewise, new features must have a SourceID to save.

Select row Delete button

Delete permanently removes a feature from your service layer. To delete a single feature, hover the cursor over a row and click the delete button.

To delete multiple features, use the checkbox to pick the features you want to delete.

Select row Approve, Unapprove buttons

Features have two statuses: approved and unapproved. Click the thumbs up button to approve a feature. Click thumbs down button to unapprove.

In general, approved features are addressed to the NHD, which means they have a ReachCode and Measure. However, HydroAdd does not strictly require approved features to be addressed. It is possible to approve features that have not been addressed. HydroAdd will warn you if you approve or save a feature that has not been addressed but does not disallow it.

Select row Edit button

Click the edit button to edit a feature. When you click the edit button, the editing pane opens, and the editing crosshair cursor appears on the map. NOTE: the map must be at zoom level 14 for the crosshair cursor to appear.

Select row Edit Queues button
