3.7 Grids
Since CHPS is a location-oriented system, all time series data must be referenced to a geographic location. For gridded time series data, you must reference each point in the grid to a location in a grid structure.
Grids may be regular or irregular.
-
Regular grids have cells with the same width, height, and area within the coordinate system specifying it.
- Irregular grids have a fixed number of rows and columns, but the cell height and width is not equal in each row and column. Additional information is required on the location of the center of each cell in order to display the grids and for use in the spatial interpolation routine, which interpolates data in between cells.
Grids.xml is located in RegionConfigFiles directory.
