UPDATE: pkg API has changed - updated the post below to work with the current CRAN version, submitted 2016-08-02 I was at a hackathon focused on Ocean Biogeographic Information System (OBIS) data back in November last year in Belgium. One project idea was to make it easier to get at data based on one or more marine regions. I was told that Marineregions.org is often used for shape files to get different regions to then do other work with....
lawn is an R wrapper for the Javascript library turf.js for advanced geospatial analysis. In addition, we have a few functions to interface with the geojson-random Javascript library. lawn includes traditional spatial operations, helper functions for creating GeoJSON data, and data classification and statistics tools. There is an additional helper function (see view()) in this package to help visualize data with interactive maps via the leaflet package (https://github.com/rstudio/leaflet). Note that leaflet is not required to install lawn - it’s in Suggests, not Imports or Depends....
geojsonio converts geographic data to GeoJSON and TopoJSON formats - though the focus is mostly on GeoJSON For those not familiar GeoJSON it is a format for encoding a variety of geographic data structures. GeoJSON supports the following geometry types: Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection. These geometry types are also found in well known text (WKT), and have equivalents in R’s spatial classes. Read the spec for more detailed information....
At rOpenSci we’ve been working on an R package (geojsonio) to make converting R data in various formats to geoJSON and topoJSON, and vice versa. We hope to do this one job very well, and handle all reasonable use cases. Functions in this package are organized first around what you’re working with or want to get, geojson or topojson, then convert to or read from various formats: geojson_list()/topojson_list() - convert to geojson/topojson as R list format geojson_json()/topojson_json() - convert to geojson/topojson as json geojson_read()``topojson_read() - read a geojson/topojson file from file path or URL geojson_write()/topojson_write() - write a geojson/topojson file locally Each of the above functions have methods for various objects/classes, including numeric, data....
