RGeo::Shapefile
is an optional module for RGeo
for reading geospatial data from ESRI shapefiles.
RGeo is a key component for writing location-aware applications in the
Ruby programming language. At its core is an implementation of the
industry standard OGC Simple Features Specification, which provides data
representations of geometric objects such as points, lines, and polygons,
along with a set of geometric analysis operations. See the README for the
rgeo
gem for more information.
RGeo::Shapefile
is an optional RGeo add-on module for reading geospatial
data from ESRI shapefiles. The shapefile format is a common file format
for geospatial data sets. It is specified in
this ESRI whitepaper.
Example:
require 'rgeo/shapefile'
RGeo::Shapefile::Reader.open('myshpfil.shp') do |file|
puts "File contains #{file.num_records} records."
file.each do |record|
puts "Record number #{record.index}:"
puts " Geometry: #{record.geometry.as_text}"
puts " Attributes: #{record.attributes.inspect}"
end
file.rewind
record = file.next
puts "First record geometry was: #{record.geometry.as_text}"
end
RGeo::Shapefile
has the following requirements:
- Ruby 2.3.0 or later
- rgeo 1.0.0 or later.
- dbf 3.0 or later.
Include in your bundle:
gem 'rgeo-shapefile'
Install RGeo::Shapefile
as a gem:
gem install rgeo-shapefile
See the rgeo
gem, a required dependency,
for further installation information.
If you are using Ruby 2.0-2.2, use version 1.0.x
of this gem.
If you are using Ruby 1.9, use version 0.3.x
of this gem.
If you are using Ruby 1.8, use version 0.2.x
of this gem.

rgeo-shapefile
was orginally written by Daniel Azuma (http://www.daniel-azuma.com).
Development is supported by:
Although we don't use shapelib (http://shapelib.maptools.org) to read ESRI shapefiles, we did borrow a bunch of their test cases.
