Generate useful, RGeo-compatible geographic points located within a supplied shapefile.
Follow the RGeo installation instructions and install RGeo.
gem install geopoint_factory
Download an ESRI-compatible shapefile. (Cartographic boundary files from the US Census are a convenient source for these.)
Initialize an instance of GeoPointFactory::Generator with a shapefile and generate points:
require 'geopoint_factory' generator = GeoPointFactory::Generator.new("path/to/shapefile") # omit file extension point_inside = generator.generate different_point_inside = generator.generate yet_another_point_inside = generator.generate generator.finalize
- When done with a Generator instance, call #finalize.
GeoPoint Factory was developed as a way to easily generate geographic coordinate data within a specific geographic area, while avoiding areas that may not be useful, such as in the ocean.
For example, using the US Census-supplied shapefile of San Francisco's boundaries, GeoPoint Factory can generate random points specifically within San Francisco's borders and avoid generating points within the Pacific Ocean or San Francisco Bay.
GeoPoint Factory was developed for use with the RGeo library.
