Abstract:
This data set consists of a set of 136 ESRI formatted GRID data sets representing elevations in meters for the state of Arizona. Each file covers a half degree block and as a collection they cover the entire State of Arizona. The data were created by processing U.S.Geological Survey 30 meter Digital Elevation Model files for all of the 7.5 minute quadrangle map areas in Arizona. The processing produced ESRI formatted lattices (GRIDs) for each quadrangle. These were then merged into the half degree blocks.
Purpose:
The data are created to serve as base information for use in GIS systems for a variety of planning and analysis purposes. These data do not represent a legal record.
Supplemental_Information:
The bounding coordinates shown in this metadata file represent a sample half degree lattice (ESRI GRID), in this case the tile named "FLAGE" (Flagstaff, East). Each GRID in the collection will have its own unique set of bounding coordinates. Transfer size will also vary per GRID. All other characteristics in this metadata file apply to all of the GRIDS in the collection.

Process_Description:
The data were processed in ARC/INFO by creating ESRI lattice (GRIDs) from all of the 7.5 minute U.S. Geological Survey Digital Elevation Model files (30 meter cell size) for Arizona utilizing ARC/INFO. The data were then merged into larger GRIDs of 135 half degree blocks which represent the Arizona Land Resources Information System (ALRIS) tiles.
