Palmetto Bay FL 33157 United States (305) 252-0347 (305) 253-0463 judd_patterson@nps.gov Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.3.0.1770 Unknown. Unknown. All vegetation polygons were created via hiking, traversing each island until all vegetation communities had been mapped and recorded. When a community was reached that clearly was distinguishable from adjacent vegetation communities, this area was mapped using the Trimble GeoXT. Consequently, the polygon outlined the extent of these vegetation communities. The two person field team consisted of a delineator with the Trimble unit and a data recorder. The delineator carefully walked the edge of the vegetation community and delineated the polygon location. With the Trimble unit on and the Terrasync program opened, the delineator was able to create a polygon and assign attributes associated with that particular polygon. Meanwhile, the data recorder took a GPS waypoint on a Garmin 60CSx (at the start location which is temporarily marked with a pvc pole) and in combination with the Garmin 60CSx unit number created a unique identifier for the polygon and associated data. An initial photograph was taken of the data sheet followed by a number of pictures of the dominant vegetation comprising the polygon along with any unique species. Some features were mapped that are not vegetation communities but were considered to be important features like sand patches between vegetation polygons, coral rubble on Bush Key and Long Key, and an ephemeral salt pond on Bush Key. In general, we began mapping at the edges of the island and worked our way inland. The shoreline of each island was walked to create a shoreline polygon on the Trimble unit except for Loggerhead Key, where a Garmin 60CSx unit was used to map the shoreline. The Garmin created a trackline which was converted to a shapefile polygon. Shoreline was defined as the water line at the time the island was walked. On Hospital, Middle, and East Keys, two dune elevations (secondary and crown dune) were also mapped. These features were considered the more stable parts of these smaller islands. 2009 Jose Luciani National Park Service - South Florida/Caribbean Network Unknown mailing and physical address
