Documentation of a Digital Spatial Data Base for Hydrologic Investigations,Broward County, Florida

摘要

Geographic information systems have become an important tool in planning for theprotection and development of natural resources, including ground water and surface water. A digital spatial data base consisting of 18 data layers that can be accessed by a geographic information system was developed for Broward County, Florida. Five computer programs, including one that can be used to create documentation files for each data layer and four that can be used to create data layers from data files not already in geographic information system format, were also developed. Four types of data layers have been developed. Each data layer is documented as to the extent of the features, number of features, scale, data sources, and a description of the attribute tables where applicable.
