Abstract:
Spatial Data Management techniques are rapidly becoming practical tools for use by Corps of Engineers field offices in a variety of their responsibilities. Various aspects of these techniques have been applied in traditional Survey and Phase I General Design Memorandum Studies and on a large scale in the Expanded Flood Plain Information XFPI studies of the Corps Flood Plain Management Services program. The use of grid data, e.g., spatial data stored in computer files in a specific grid cell format, has been determined to be the only spatial data management technique that offers significant analytical opportunities when compared to polygon oriented approaches. The grid structure successfully used in applications to date have included square, rectangular, and triangular cells, the latter being an emerging method with particular potential in the Management of terrain topographic data. This manual is intended to be initial documentation of the basic procedures that are necessary for the successful creation of a grid cell data bank. The manual was prepared primarily to aid the XFPI pilot studies in which gridded data banks are being created as a major focal point of the studies. However, anyone interested in spatial data management should find that the manual contains valuable information.
