Florida 1986-1991

Methods


General Methods
Sampling & coverage of blocks

Each block consists of 1/6 of a USGS 7.5 minute topographic quad. Minimum of 2 priority blocks were sampled from each quad. Many non-priority blocks were also sampled.

Coordination of coverage
Florida was divided into 9 regions, and management of this project was accomplished with the help of regional coordinators. County coordinators also worked with the regional coordinators. See the List of Coordinators on the project site.
