ABSTRACT Spatial analyses involving binning often require that every bin have the same area, but this is impossible using a rectangular grid laid over the Earth or over any projection of the Earth. Discrete global grids use hexagons, triangles, and diamonds to overcome this issue, overlaying the Earth with equally-sized bins. Such discrete global grids are formed by tiling the faces of a polyhedron. Previously, the orientations of these polyhedra have been chosen to satisfy only simple criteria… Expand
A novel method of determining the optimal polyhedral orientation for discrete global grid systems applicable to regional-scale areas of interest
Results show that the orientation determined by this method successfully guarantees that target areas are located at the center of a single polyhedral face and effectively handles geospatial data at a global scale because of the inherent characteristics of DGGSs. Expand
Integration of heterogeneous terrain data into Discrete Global Grid Systems
ABSTRACT The Canadian Digital Elevation Model (CDEM) and the High-Resolution Digital Elevation Model (HRDEM) released by Natural Resources Canada are primary terrain data sources in Canada. Due toExpand
Bayesian nonparametric nonhomogeneous Poisson process with applications to USGS earthquake data
A nonparametric Bayesian method for estimating the spatial point process intensity based on mixture of finite mixture (MFM) model that leads to a consistent estimate of the intensity of spatial point patterns in different areas while considering heterogeneity is proposed. Expand
BusTr: Predicting Bus Travel Times from Real-Time Traffic
BusTr, a machine-learned model for translating road traffic forecasts into predictions of bus delays used by Google Maps, is presented, demonstrating that the neural sequence model improves over DeepTTE, the state-of-the-art baseline, both in performance and training stability. Expand
Finding Antarctica’s Pole of Inaccessibility
Abstract Antarctica’s Pole of Inaccessibility (Southern Pole of Inaccessibility (SPI)) is the point on the Antarctic continent farthest from its edge. Existing literature exhibits disagreement overExpand


Geodesic Discrete Global Grid Systems
In recent years, a number of data structures for global geo-referenced data sets have been proposed based on regular, multi-resolution partitions of polyhedra. We present a survey of the mostExpand
Comparing Area and Shape Distortion on Polyhedral-Based Recursive Partitions of the Sphere
Five different methods for mapping from the polyhedral model to the surface of the sphere are used: the Gnomonic projection, Fuller's Dymaxion projection, Snyder's equal area polyhedral projection, direct spherical subdivision, and a recursivepolyhedral projection. Expand
Traversing the Triangle Elements of an Icosahedral Spherical Representation in Constant-Time
Techniques are presented for moving between adjacent triangles of equal size in a hierarchical representation for spherical data that is projected onto the faces of an icosahedron. The faces of theExpand
Comparing Geometrical Properties of Global Grids
Transforming raw observations into geometrically regular global grids is a fundamental data processing and storage problem underlying much of our global data analysis. The basic geometry ofExpand
Algebraic encoding scheme for aperture 3 hexagonal discrete global grid system
This paper presents an algebraic model of encoding scheme for the Aperture 3 Hexagonal (A3H) DGGS and proves that cell centers at different levels can be represented exactly using a mixed positional number system in the complex plane through the recursive geometric relationship between two successive levels, which reveals that grid cells are essentially special complex radix numbers.

An Equal-Area Map Projection For Polyhedral Globes
Numerous polyhedral shapes have been proposed as approximations for globes, and the projection most often used is the Gnomonic, with considerable scale and area distortion. Complicated conformalExpand
