Hexagonal Convolutional Neural Networks for Hexagonal Grids [PDF]
IEEE Access, 2019 Hexagonal grids use a hierarchical subdivision tessellation to cover the entire plane or sphere. Due to the 6-fold rotational symmetry, hexagonal grids have some advantages (e.g.

Research and Construction of a Global Hexagonal Marine Gravity Gradient Reference Map for Navigation
Geofluids, 2023 A high-precision marine gravity gradient reference map is key to enabling underwater gravity gradient matching navigation. At present, the construction of the reference maps is based on quadrilateral geographic grids. However, quadrilateral grids lead to

Blue-noise halftoning for hexagonal grids [PDF]
IEEE Transactions on Image Processing, 2006 In this paper, we closely scrutinize the spatial and spectral properties of aperiodic halftoning schemes on rectangular and hexagonal sampling grids. Traditionally, hexagonal sampling grids have been shunned due to their inability to preserve the high-frequency components of blue-noise dither patterns at gray-levels near one-half, but as will be shown,

Geostrophic Adjustment on Hexagonal Grids
Monthly Weather Review, 2002 A simple two-dimensional linearized model of the atmosphere is used to investigate behavior of the geostrophic adjustment process on five selected horizontal hexagonal grids. This study shows that hexagonal lattices have some advantages over commonly used square grids.

HEXAGONAL GRIDS APPLIED TO CLUSTERING LOCATIONS IN WEB MAPS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 One of the popular ways to clutter reduction techniques is to combine neighboring points into one marker that somehow shows that it contains multiple entities – this way is called clustering.
