Hydrogeologic Unit Depths at 321 Sites in South Florida

USGS, in cooperation with SFWMD and Broward County, developed this point data layer containing hydrogeologic unit depths and generalized land-surface elevations for 321 selected sites. The data was digitized from published cross sections and contour maps for water-resources investigations. It was published as part of a 1992 report (WRIR 92-4061) and last updated in the system in 2002.

Use Cases

• Model groundwater flow by analyzing the spatial distribution of hydrogeologic unit depths across the 321 points.
• Create contour maps of aquifer thickness or unit elevations using the point depth and land-surface elevation data.
• Assess regional hydrogeologic structure by correlating unit depths between the published cross sections used as source material.
• Support water-resource risk assessments by integrating the depth point layer with other GIS data layers on canals, lakes, or municipal boundaries.

Strengths

• Contains 321 spatially referenced data points for analysis.
• Data was derived from authoritative published cross sections and contour maps by the USGS.

Limitations

• Sample size is limited to 321 points, which may not provide dense coverage for high-resolution modeling.
• Data is temporally stale, with source material from a 1992 report and a last update recorded in 2002.
• Specific column names and data formats are unknown, complicating immediate use.
