lakemorpho

The purpose of lakemorpho is to provide a suite of tools that can be used to calculate basic lake morphometry metrics from an input SpatialPolygonsDataframe of a lake and a digital elevation model, as a RasterLayer, for the terrain surrounding that lake. These tools are being used to calculate lake morphometry metrics for all "lakepond" waterbodies in the NHDPlus V2.

Metrics Included

lakemorpho calculates the following metrics

• Surface Area
• Shoreline Length
• Shoreline Development
• Maximum Depth
• Mean Depth
• Lake Volume
• Maximum Lake Length
• Mean Lake Width
• Maximum Lake Width
• Fetch from a specified bearing
