Triangulated irregular network

摘要

Methods and other embodiments associated with performing an in-memory triangulation of a large data set are described. One example method for performing in-memory triangulation of a large data set includes partitioning a large geographical information data set into a set of stripes and generating, in-memory, a set of local triangulated irregular networks (TINs) corresponding to members of the set of stripes. Information associated with triangles associated with the set of local TINs are stored.
