AOI. Area of Interest.

Role: Author, Creator

If you’ve ever found yourself needing to geocode or reverse geocode a location, formalize an area of interest, get bounding geometries, decribe a place by lat/long, or better understand spatial locations this package should be able to help. An area of interest (AOI) is a geographic extent. It helps confine and formalize a unit of work to a geographic area, and prioritize and define research and sub setting efforts while improving reproducibility. They are built around concrete spatail attributes but often are discussed in a more colloquail way. The aim of the is package is to help make the colloquial understanding of space more concrete.

NFHL. R Interface to the FEMA National Flood Hazards Layer.

Role: Author, Creator

The goal of NFHL is to provide access to the National Flood Hazards Layers using the AOI subsetting workflows. Some preliminary thoughts on making this data more ‘serviceable’ are also given.

NWM. An R client for the National Water Model.

Role: Author, Creator

Each day the NOAA NWM produces ~400 GB of forecast data for the CONUS. This data is stored for a 40 day rolling window on the HydroShare Thredds server amounting to over 16,000 GB (2 TB) of data being stored and accessible at any one time. This package aims to provide access to this data in a clean, fast, and convenient way through the R environment.
