Riverscape Inundation Mapper (RIM) tool

Step 1 Gather Inputs

The first step to mapping your riverscape and running the tool is to gather the required input files.

Inputs

The required inputs to use the Riverscape Inundation Mapper tool in full are:

  • imagery
  • Digital Elevation Model (DEM)

Imagery

Potential sources of imagery include Unmanned Aerial Vehicle (UAV) orthomosaics, imagery from the National Agriculture Imagery Program (NAIP), Google Earth, Light Detection and Ranging (LIDAR) data, and more.

DEM

We typically use USGS National Elevation Dataset (NED) 1/3 arc second (~ 10 m) DEM data.

The following optional inputs are useful and provide additional context for valley bottom mapping and information about the local hydrology:
