FedData is an R package implementing functions to automate downloading geospatial data available from several federated data sources (mainly sources maintained by the US Federal government).

FedData version 2.5 will be the final minor CRAN release of FedData 2. FedData 3 will be released in the coming months, but some code built on FedData 2 will not be compatible with FedData 3.

Currently, the package enables extraction from seven datasets:

This package is designed with the large-scale geographic information system (GIS) use-case in mind: cases where the use of dynamic web-services is impractical due to the scale (spatial and/or temporal) of analysis. It functions primarily as a means of downloading tiled or otherwise spatially-defined datasets; additionally, it can preprocess those datasets by extracting data within an area of interest (AoI), defined spatially. It relies heavily on the sp, raster, and rgdal packages.

This package has been built and tested on a source (Homebrew) install of R on macOS 10.13 (High Sierra), and has been successfully run on Ubuntu 14.04.5 LTS (Trusty), Ubuntu 16.04.1 LTS (Xenial) and binary installs of R on Mac OS 10.13 and Windows 10.

FedData was reviewed for rOpenSci by @jooolia, and was greatly improved as a result. rOpenSci onboarding was coordinated by @sckott.
