elevatr - Access Elevation Data from Various APIs

Several web services are available that provide access to elevation data. This package provides access to many of those services and returns elevation data either as an 'sf' simple features object from point elevation services or as a 'raster' object from raster elevation services. In future versions, 'elevatr' will drop support for 'raster' and will instead return 'terra' objects. Currently, the package supports access to the Amazon Web Services Terrain Tiles <https://registry.opendata.aws/terrain-tiles/>, the Open Topography Global Datasets API <https://opentopography.org/developers/>, and the USGS Elevation Point Query Service <https://apps.nationalmap.gov/epqs/>.

lakemorpho - Lake Morphometry Metrics

Lake morphometry metrics are used by limnologists to understand, among other things, the ecological processes in a lake. Traditionally, these metrics are calculated by hand, with planimeters, and increasingly with commercial GIS products. All of these methods work; however, they are either outdated, difficult to reproduce, or require expensive licenses to use. The 'lakemorpho' package provides the tools to calculate a typical suite of these metrics from an input elevation model and lake polygon. The metrics currently supported are: fetch, major axis, minor axis, major/minor axis ratio, maximum length, maximum width, mean width, maximum depth, mean depth, shoreline development, shoreline length, surface area, and volume.

nsink - Flow path nitrogen removal estimation

N-Sink is an analysis that utilizes geospatial data to estimate a flow path and the nitrogen removal along that flow path. Additionally, several static maps summarizing nitrogen removal may be summarized. The nsink package provides tools to setup and run this analysis for any HUC in the United States.

quickmapr - Quickly Map and Explore Spatial Data

While analyzing geospatial data, easy visualization is often needed that allows for quick plotting, and simple, but easy interactivity. Additionally, visualizing geospatial data in projected coordinates is also desirable. The 'quickmapr' package provides a simple method to visualize 'sp', 'sf' (via coercion to 'sp'), and 'raster' objects, allows for basic zooming, panning, identifying,labeling, selecting, and measuring spatial objects. Importantly, it does not require that the data be in geographic coordinates.
