Watershed delineation on a hexagonal mesh grid
Environmental Modelling & Software, 2020 Abstract Spatial discretization is the cornerstone of all spatially-distributed numerical simulations including watershed hydrology. Traditional square grid spatial discretization has several limitations including inability to represent adjacency uniformly.

IMPROPER COLORING OF WEIGHTED GRID AND HEXAGONAL GRAPHS [PDF]
Discrete Mathematics, Algorithms and Applications, 2010 We study a weighted improper coloring problem motivated by a frequency allocation problem. It consists of associating to each vertex a set of p(v) (weight) distinct colors (frequencies), such that the set of vertices having a given color induces a graph of degree at most k (the case k = 0 corresponds to proper coloring).

Indexing Mixed Aperture Icosahedral Hexagonal Discrete Global Grid Systems
ISPRS International Journal of Geo-Information, 2020 Discrete global grid systems (DGGSs) are an emerging multiresolution 3D model used to integrate and analyze big earth data. The characteristic of multiresolution is usually realized by hierarchically subdividing cells on the sphere using certain ...

An Occupancy Information Grid Model for Path Planning of Intelligent Robots
ISPRS International Journal of Geo-Information, 2022 Commonly used robot map models include occupancy grid maps, topological maps, and semantic maps. Among these, an occupancy grid map is mainly represented as a quadrilateral grid. This paper proposes an occupancy information grid for intelligent robots by
