Moving-Window and Direct Data Aggregation
Data aggregation via moving window or direct methods. Aggregate a fine-resolution raster to a grid. The moving window method smooths the surface using a specified function within a moving window of a specified size and shape prior to aggregation. The direct method simply aggregates to the grid using the specified function.

View DocumentationTools for Validating GeoJSON
Tools for linting GeoJSON. Includes tools for interacting with the online tool http://geojsonlint.com, the Javascript library geojsonhint (https://www.npmjs.com/package/geojsonhint), and validating against a GeoJSON schema via the Javascript library (https://www.npmjs.com/package/is-my-json-valid). Some tools work locally while others require an internet connection.

Generate random positions (latitude/longitude), Well-known text (WKT) points or polygons, or GeoJSON points or polygons.
View DocumentationParse Messy Geographic Coordinates
Parse geographic coordinates from various formats to decimal degree numeric values. Parse coordinates into their parts (degree, minutes, seconds); calculate hemisphere from coordinates; pull out individually degrees, minutes, or seconds; add and subtract degrees, minutes, and seconds. C++ code herein originally inspired from code written by Jeffrey D. Bogan, but then completely re-written.

Tools to get marine regions data from http://www.marineregions.org/. Includes tools to get region metadata, as well as data in GeoJSON format, as well as Shape files. Use cases include using data downstream to visualize geospatial data by marine region, mapping variation among different regions, and more.
View DocumentationLandscape Utility Toolbox
Provides utility functions for some of the less-glamorous tasks involved in landscape analysis. It includes functions to coerce raster data to the common tibble format and vice versa, it helps with flexible reclassification tasks of raster data and it provides a function to merge multiple raster. Furthermore, landscapetools helps landscape scientists to visualize their data by providing optional themes and utility functions to plot single landscapes, rasterstacks, -bricks and lists of raster.
Scientific use casesA Tidy Approach to NetCDF Data Exploration and Extraction
Tidy tools for NetCDF data sources. Explore the contents of a NetCDF source (file or URL) presented as variables organized by grid with a database-like interface. The hyper_filter() interactive function translates the filter value or index expressions to array-slicing form. No data is read until explicitly requested, as a data frame or list of arrays via hyper_tibble() or hyper_array().
View DocumentationClasses for GeoJSON
Classes for GeoJSON to make working with GeoJSON easier. Includes S3 classes for GeoJSON classes with brief summary output, and a few methods such as extracting and adding bounding boxes, properties, and coordinate reference systems; working with newline delimited GeoJSON; linting through the geojsonlint package; and serializing to/from Geobuf binary GeoJSON format.

Scientific use casesCreate Geographic and Non-Geographic Map Tiles
Creates geographic map tiles from geospatial map files or non-geographic map tiles from simple image files. This package provides a tile generator function for creating map tile sets for use with packages such as leaflet. In addition to generating map tiles based on a common raster layer source, it also handles the non-geographic edge case, producing map tiles from arbitrary images. These map tiles, which have a non-geographic, simple coordinate reference system (CRS), can also be used with leaflet when applying the simple CRS option. Map tiles can be created from an input file with any of the following extensions: tif, grd and nc for spatial maps and png, jpg and bmp for basic images. This package requires Python and the gdal library for Python. Windows users are recommended to install OSGeo4W (https://trac.osgeo.org/osgeo4w/) as an easy way to obtain the required gdal support for Python.

Scientific use casesSimulating Neutral Landscape Models
Provides neutral landscape models (doi:10.1007/BF02275262,
http://sci-hub.tw/10.1007/bf02275262).
Neutral landscape models range from “hard”
neutral models (completely random distributed), to “soft” neutral models
(definable spatial characteristics) and generate landscape patterns that are
independent of ecological processes.
Thus, these patterns can be used as null models in landscape ecology. nlmr
combines a large number of algorithms from other published software for
simulating neutral landscapes. The simulation results are obtained in a
geospatial data format (raster* objects from the raster package) and can,
therefore, be used in any sort of raster data operation that is performed
with standard observation data.
