My previous blog post reviewed the concept of the Hausdorff distance  (which more descriptively could be called farthest distance .) Despit...

The  Hausdorff Distance is a useful spatial function which can appear slightly mysterious. Partly this is due to the name.  It honours  Fel...

Some spatial use cases require identifying "narrow" or "skinny" polygons.  A classic example is the process of cleaning ...

The JTS Topology Suite has been rolling out the capability to manage  polygonal coverages .  It supports modelling polygonal coverages as a...

A previous post introduced a new algorithm in the JTS Topology Suite called RelateNG .  It computes topological relationships between geome...

The most fundamental and widely-used operations in the JTS Topology Suite are the ones that evaluate topological relationships between geo...
