How to Add a GIS Shapefile to a HEC-RAS Model?

This video details how to add a GIS shapefile for a HEC‑RAS model.

Follow these steps to add a GIS shapefile to a GeoHECRAS project:

  1. Right-click on Map Data Layer panel and then select Add Layers from the displayed context menu.Add a GIS Shapefile to a HEC-RAS Model menu
  2. The Add Layers dialog box will appear.Add Layers dialog box
  3. Select the GIS shapefile(s) to load. Hold down the [Ctrl] key to load more than one shapefile at the same time.
  4. The selected shapefile(s) will be loaded into the Map View and Map Data Layers panel. If more than one shapefile was selected, the selected shapefiles will be placed within their own layer group.Add a GIS Shapefile Layer Group
  5. To rename the layer group, highlight the layer group and either right-click and select Rename from the displayed context menu or press the [F2] function key.Renaming a Layer Group
  6. If the imported shapefiles do not have an assigned coordinate reference system (CRS), see this section on how to georeference the shapefiles to the Map View.

Drag and Drop

Shapefiles can also be dragged and dropped from Windows Explorer onto the Map View or Map Data Layers panel. Dropping the shapefiles on to the Map Data Layers panel provides more control on the display order of the selected shapefiles.
