A Computerized Data-Base System for Land-Use and Land-Cover Data Collected at Ground-Water Sampling Sites in the Pilot National Water Quality Assessment Program

Scott, Jonathon C.

Abstract:

Data-base software has been developed for the management of land-use and land-cover data collected by the U.S. Geological Survey as part of a pilot program to test and refine concepts for a National Water-Quality Assessment Program. This report describes the purpose, use, and design of the land-use and land-cover data-base software. The software provides capabilities for interactive storage and retrieval of land-use and land-cover data collected at ground-water sampling sites. Users of the software can add, update, and delete land-use and land-cover data. The software also provides capabilities to group, print, and summarize the data. The land-use and land-cover data-base software supports multiple data-base systems so that data can be accessed by persons in different offices. Data-base systems are organized in a tiered structure. Each data-base system contains all the data stored in the data-base systems located in the lower tiers of the structure. Data can be readily transmitted from lower tiers to high tiers of the structure. Therefore, the data-base system at the highest tier of the structure contains land-use and land-cover data for the entire pilot program.
