Description:
Abstract:
This polygon GIS data set represents a compilation of statewide seagrass data from various source agencies and scales. The data sources were mapped from photography ranging in date from 1987 to 1999. The original source data sets were not all classified in the same manner; some used the Florida Land Use Cover and Forms Classification System (FLUCCS) codes 9113 for discontinuous seagrass and 9116 for continuous seagrass; some defined only presence and absence of seagrass, and some defined varying degrees of seagrass percent cover. In order to merge all of these data sources into one compilation data set, FMRI reclassified the various source data attribute schemes into two categories: "continuous" and "discontinuous" seagrass.
Purpose:
This data set is an update to include 1999 data in the statewide seagrass data set.
Supplemental_Information:
These data are for statewide mapping and analysis only. More recent data are available from FMRI for the South Florida Water Management District area. The original regional data sets may contain more detailed seagrass attribution schemes. Contact GIS Librarian to request the source data sets.

FMRI reclassified these data as follows:
Data coded as "Continuous Seagrass" remained unchanged.
Data coded as "Patchy (Discontinuous) seagrass" was relabeled "Discontinuous" seagrass
Data coded as "Hardbottom with seagrass" were reclassified as "Discontinuous" seagrass

The class "CSG" (continuous seagrass 86 to 100 percent cover) was classified as "continuous" seagrass. The four categories of "PSG" (patchy seagrass ranging between 1 and 85 percent cover) were classified as "discontinuous" seagrass.

Process_Step:
Process_Description:
FMRI staff MAPJOINed seven regional seagrass data sets using ArcInfo Workstation. The source data sets had different attribute schemes, that FMRI staff consolidated into two categories for this data set: "continuous " and "discontinuous" seagrass. In areas of overlap between source data sets, the more recent source was used. No edgematching was performed between data sets of differing source dates. FMRI converted these data to shapefile and geodatabase format for additional analyses. Data have been UNIONed with county boundaries extended beyond Florida state waters. The final data are stored in ArcSDE.
