Abstract:
The NW seagrass GIS data set was created by the United States Geological Survey (USGS) Biological Resources Division (BRD) at the National Wetlands Research Center (NWRC) in Lafayette, LA. The study area is from Anclote Key to Perdido Bay on the Alabama-Florida state line. The aerial photos were obtained in December of 1992 and early 1993. Photos were 1:24,000 natural color. Aerial photos were interpreted and delineated by USGS, then transferred to a base map using a zoom transfer scope. The maps were digitized into ARC/INFO. There are a few data gaps in the data set due to a lack of complete aerial photo coverage in the Panhandle region (West Bay and Escambia Bay).
Purpose:
To map spatial distribution of seagrasses in northwest Florida for scientific and GIS analysis.
Supplemental Information: Oysters and bare substrate were also mapped wherever they were found close to seagrasses. This is not intended to include a complete oyster reef data set. Despite being over ten years old, these are the best available seagrass data for this area.

Attribute Accuracy:

Attribute Accuracy Report:
Interpreted photos were quality checked by two photo interpreters for attribute classification. Field verification was performed for areas where attribute classification was questionable. Local personnel with state and federal agencies assisted in field identification. The mylar-based 1:24,000-scale maps were checked by cartographic personnel for line and labelworks. The attribute accuracy is tested manually comparing hard copy plots of the data with the source materials. When attributes cannot be visually verified on plots they are interactively queried and verified on screen. In addition, the attributes are compared against a master set of valid attributes.
