Bloch Description

Simplify linework in polygonal geographic datasources Bloch is a module to simplify linework in polygonal geographic datasources.Inspired by Matthew Bloch's MapShaper thesis (http://mapshaper.org), Bloch can load OGR-compatible data sources and simplify the linework while preserving topology. The simplify() method accepts tolerances in map units, so simplification can be performed by known amounts with predictable outcomes.Dependencies include Warmerdam (http://trac.osgeo.org/gdal/wiki/GdalOgrInPython) and Gillies (http://trac.gispython.org/lab/wiki/Rtree, http://trac.gispython.org/lab/wiki/Shapely). Requirements: · Python
