METHOD FOR DETERMINING RELATIVE SUITABILITY OF EXISTING GEOTECHNICAL DATA FOR REGIONAL PLANNING
During regional planning studies, the engineering geologists must choose among diverse, competing data sources, each having distinct cost and accuracy characteristics. Recognizing a need for guidelines in this area, the Missouri Division of Geology and Land Survey, Rolla Missouri, evaluated a sequence of alternative sources of data on the Cape Girardeau quadrangle in southeastern Missouri. Several map sources were compared at three scales: statewide (1:500 000), countywide (1:62 000), and quadrange (1:24 000). Engineering and geologic considerations were used to establish criteria for 10 land uses associated with residential development. These criteria were used with the appropriate source data to develop a sequence of limitations maps at each scale. Extensive field and laboratory programs were carried out to prepare the best-possible data-reference source with which other map products could be compared. A usefulness index was formulated to measure the degree of agreement between the competing interpreted products and the reference standards. Manual computation of this index proved impractical (a 10-km sq (4-mile sq) area required 1 person day/comparison). Thus, computer methods were used that permitted the rapid comparison of approximately 32000 cells covering the quadrangle and the computation of the resulting usefulness index for about $50.00 (including all salaries and data-processing costs).
