Duality and Dimensionality Reduction Discrete Line Generation Algorithm for a Triangular Grid

Vectors are a key type of geospatial data, and their discretization, which involves solving the problem of generating a discrete line, is particularly important. In this study, we propose a method for constructing a discrete line mathematical model for a triangular grid based on a “weak du...
