English: Part a shows a rectilinear grid in the horizontal plane. Part b shows a curvilinear grid in the horizontal plane. Part c shows a z-level grid structure in the vertical plane. Part d shows a s-level grid structure in the vertical plane. This figure is taken from Delandmeter and van Sebille 2019 (Delandmeter, P. and van Sebille, E.:
GRIB (GRIdded Binary or General Regularly-distributed Information in Binary form [1]) is a concise data format commonly used in meteorology to store historical and forecast weather data. It is standardized by the World Meteorological Organization 's Commission for Basic Systems, known under number GRIB FM 92-IX, described in WMO Manual on Codes ...
Bathymetric Attributed Grid (BAG) is a file format designed to store and exchange bathymetric data. The implementation of the format was triggered by the large adoption of gridded bathymetry and the need of transferring the required information about bathymetry and associated uncertainty (i.e., metadata) between processing applications.
Because a grid is a sample of a continuous space, raster data is most commonly used to represent geographic fields, in which a property varies continuously or discretely over space. Common examples include remote sensing imagery, terrain/elevation , population density , weather and climate , soil properties , and many others.
(More generally, coarse grid unknowns can be particular linear combinations of fine grid unknowns.) Thus, AMG methods become black-box solvers for certain classes of sparse matrices . AMG is regarded as advantageous mainly where geometric multigrid is too difficult to apply, [ 20 ] but is often used simply because it avoids the coding necessary ...
It provides a rich Excel-like user interface and its built-in vector programming language FPScript has a syntax similar to MATLAB. FreeMat, an open-source MATLAB-like environment with a GPL license. GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command-line interface for solving ...
Occupancy Grid Mapping refers to a family of computer algorithms in probabilistic robotics for mobile robots which address the problem of generating maps from noisy and uncertain sensor measurement data, with the assumption that the robot pose is known. Occupancy grids were first proposed by H. Moravec and A. Elfes in 1985.
In computer science, a grid file or bucket grid is a point access method which splits a space into a non-periodic grid where one or more cells of the grid refer to a small set of points. Grid files (a symmetric data structure ) provide an efficient method of storing these indexes on disk to perform complex data lookups.
