De-9im intersection matrix
The Dimensionally Extended 9-Intersection Model (DE-9IM) is a topological model and a standard used to describe the spatial relations of two regions (two geometries in two-dimensions, R ), in geometry, point-set topology, geospatial topology, and fields related to computer spatial analysis. The … See more The DE-9IM model is based on a 3×3 intersection matrix with the form: where $${\displaystyle \dim }$$ is the dimension of the intersection (∩) of the interior See more The DE-9IM offers a full descriptive assertion about the two input geometries. It is a mathematical function that represents a complete set of all possible relations about two … See more • Point Set Theory and the DE-9IM Matrix • Illustrated Tutorial for DE-9IM See more Any topological property based on a DE-9IM binary spatial relation is a spatial predicate. For ease of use "named spatial predicates" have been defined for some common relations, which later became standard predicates.
