Adding a Base Map Layer

A base map layer provides high-quality background aerial and other imagery from different online map providers to add context to the engineering data being displayed on the Map View.

This video demonstrates how to add a base map layer.

Follow these steps to add a base map layer to a GeoHECRAS project:

  1. Right-click on the Map Data Layers panel and then select Add Base Map Layer from the displayed context menu.
