![]() ![]() Development was greatly assisted by the accepted answer to this forum post and by the pyroots Python implementations of Brent's method. The original production of this plugin for QGIS2 was undertaken by Roy Ferguson Consultancy Ltd funded by Zero Waste Scotland Ltd. Note that while QGIS will allow you to change the CRS for the project/layer, doing so is not enough as it does not save the data and only reprojects the view for the user. If you are using geographical coordinates you must save your dataset using a Projected Coordinate System (It is recommended that you use either a local or equal area projection). The Polygon Divider expects planar geometry (x,y coordinates) and will not divide geographical coordinates (degrees). Please do get in touch with a copy of any polygons that do not work, they will help us continue to improve this plugin! Data Considerations: If you find that it doesn't manage to divide a certain geometry at all, then you can normally remedy this by simplifying it a little. In cases where the algorithm finds the geometry difficult to divide, it will make the polygons slightly less square and more rectangular (as is illustrated in both of the above examples). #Simple divider vector landing page softwareThe software should work well on some quite complex polygons:
