Access Grid Specifications

Use the Access Grid Specifications option to load or clear a set of specifications. Specifications are defined through the Create Grid Specifications option.

A specification file contains (amongst other things), the minimum and maximum easting and northing and the grid size. Many functions in Grid Calc do not require specifications, however, some do. If you are generating a set of grids interactively, it will be easier with specifications loaded. The specifications are stored in a file named <proj><area>.gdc_spec.
