Traditionally, these metrics are calculated by hand, with\nplanimeters, and increasingly with commercial GIS products. All\nof these methods work; however, they are either outdated,\ndifficult to reproduce, or require expensive licenses to use.\nThe 'lakemorpho' package provides the tools to calculate a\ntypical suite of these metrics from an input elevation model\nand lake polygon. The metrics currently supported are: fetch,\nmajor axis, minor axis, major/minor axis ratio, maximum length,\nmaximum width, mean width, maximum depth, mean depth, shoreline\ndevelopment, shoreline length, surface area, and volume.", "RoxygenNote": "7.2.3", "Config/pak/sysreqs": "libabsl-dev cmake libgdal-dev gdal-bin libgeos-dev\nlibssl-dev libproj-dev libsqlite3-dev libudunits2-dev", "Repository": "https://usepa.r-universe.dev", "Date/Publication": "2024-09-25 14:37:54 UTC", "RemoteUrl": "https://github.com/usepa/lakemorpho2", "RemoteRef": "HEAD", "RemoteSha": "2ac7de7400d7088cba01b0e6343e1a53dc7bf823", "NeedsCompilation": "no", "Packaged": { "Date": "2026-06-04 10:26:45 UTC", "User": "root" }, "Author": "Jeffrey W.
