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.

For a detailed description of the package and its use, see:

Hollister J and Stachelek J. lakemorpho: Calculating lake morphometry metrics in R [version 1; referees: 2 approved]. F1000Research 2017, 6:1718 (doi: 10.12688/f1000research.12512.1)
