The JTS Topology Suite has been rolling out the capability to manage polygonal coverages. It supports modelling polygonal coverages as arrays of discrete polygonal geometries. This is simple to work with and allows using all of the wide variety of JTS algorithms. Coverage topology allows...

A previous post introduced a new algorithm in the JTS Topology Suite called RelateNG. It computes topological relationships between geometries using the Dimensionally-Extended 9 Intersection Model (DE-9IM) model. This algorithm is fundamental to a large proportion of spatial queries executed in...

The most fundamental and widely-used operations in the JTS Topology Suite are the ones that evaluate topological relationships between geometries. JTS implements the Dimensionally-Extended 9 Intersection Model (DE-9IM), as defined in the OGC Simple Features specification, in the RelateOp...
