Two files comprise a composite soil map for Miami-Dade County, Florida, at a 1:40,000 scale. The Soil Conservation Service issued the original maps in April 1958. Data was processed for GIS analysis using image processing and digitizing techniques.

Use Cases

• Analyze historical soil type polygons for land use change detection over time.
• Extract soil boundary features from the shapefile for regional environmental modeling.
• Use the composite map layer for comparative studies against modern soil surveys.
• Process the scanned graphic data to semi-automatically generate updated GIS layers.

Strengths
