Everglades Depth Estimation Network (EDEN) offers consistent and documented datasets that can be used to guide large-scale field operations, to integrate hydrologic and ecological responses, and to support biological and ecological assessments that measure ecosystem responses to the Comprehensive Everglades Restoration Plan. To allow for simplicity of design and use, the EDEN area was broken into a large number of equal-sized 400 x 400 meter rectangles ("Cells") that in total are referred to as the "grid". The origin and extent of the EDEN grid were selected to cover not only existing Airborne Height Finder (AHF) data from the ground elevation model and current regions of interest for Everglades restoration, but to cover a rectangular area that includes all landscape units and conservation areas in place at the time of its development. Combined with the chosen extent, the 400m cell resolution produces a grid that is 675 rows and 375 columns (253,125 cells total).
