Efficient encoding and spatial operation scheme for aperture 4 hexagonal discrete global grid system
International Journal of Geographical Information Science, 2013 Discrete global grid systems (DGGSs) are considered to be promising structures for global geospatial information representation. Square and triangular DGGSs have had the advantage over hexagonal ones in geospatial data processing over the past few ...

Spherical Geodesic Bounds and a k-Circle Coverage Formulation
ISPRS International Journal of Geo-InformationIn this article, we introduce analogues of classic Euclidean bounds, including spherical caps, geodesic axis-aligned bounding boxes (AABBs), geodesic oriented bounding boxes (OBBs), and geodesic k-discrete oriented polytopes (k-DOPs). We also formulate k-
