Documentation for # Shapy
v0.1
Author: Karim Bahgat
Year: 2014
Description:
A lightweight and portable pure-Python version of Shapely for geometry processing.
Introduction:
As the name suggests, Shapy is a pure-Python version of Shapely. It is used for geometrical and geographical problem-solving.
Based on and modelled precisely after Shapely, so should be easy to use by those familiar with Shapely...
Also some functionality that's not available in Shapely.
Dependencies:
Absolutely no dependencies, though it probably won't work on Python3 yet.
Usage:
The package is not yet complete. Currently the supported features are:
- All shapely geometries can be created (Point,MultiPoint,LineString,MultiLineString,Polygon,MultiPolygon)
- All geometries have the basic shapely attributes with correct values:
- .geom_type, .bounds, .area, .length
- all geometries also have the .geo_interface geojson attribute
- Easily visualize all geometries with the .view() method. Note: The coordinate converter has some quirks so might not show the shape correctly or at all.
- Easily make geometries from real shapefiles by passing any object that has the geo_interface to the
geoj2geom(object)
function. - Point geometries can use the .distance() method to any other geometry.
- The intersect(), union(), difference(), symmetric_difference() methods can be used by Polygon and MultiPolygon geometries, but currently only with other Polygon or MultiPolygon geometries.
- The buffer() method can be used by Polygons and MultiPolygons.
Docs are not yet completed, but just follow the shapely usage and names and you should be alright.
There's still a few things left to add, so it would be great if others could contribute some of the remaining functionality.
