applications Barrodale Computing Services Ltd. (BCS) 2. What is
Gridded Data? Multi-dimensional rectangular array of grid
pointscontaining values Gridded data occurs in many application
areas Aspects of gridded data: Dimensionality Spacing Number and
type of values stored at each grid point Types of extractions 2 3.
Gridded Data Application AreasModeling applications Meteorology
Oceanography Climate Modeling Fluid DynamicsData analysis
applications Nondestructive testing Geophysics Medical Imaging 3 4.
Grid Concepts Dimensionality: 1D, 2D, 3D, or 4D Spacing: equal or
non-equal Number and types of values stored at grid points Missing
values Data can be extracted from grids in many different ways... 4
5. Extracting Data From Grids The extracted grid may have the same
number ofdimensions as the original grid, or it may have fewer An
axis in the extracted grid may be parallel to an axis inthe
original grid, or it may not be The grid points in the extracted
grid may or may notcoincide with grid points in the original grid5
