- Description:

- Abstract:
-
Casco_Bay_Boat_Survey_Transects contains lines indicating the approximate location of fringing marsh found along the coast of Casco Bay, Maine in seven days of planned transects by boat along that coastline during the summer of 2007. Handheld GPS units (Garmin GPS76) were used to record approximate fringing marsh locations as the boat slowly cruised the shoreline. A GPS point was entered at the start of a marsh, the stop of a marsh, and any intermediary location of interest. Some very small marshes were represented by a single point. The lines of this shape file indicate the path of the boat during this survey as it paralleled marsh locations (a line indicates that a marsh was located along the shoreline approximately parallel to that line).
- Purpose:
-
This data was created as an accuracy test of the image-based delineation of marshes performed for the Casco Bay Fringing Marsh Mapping and Assessment. Buffered image-delineated marshes were intersected with actual marshes (as determined by the lines in this shape file) and the fraction of actual marshes detected estimated as a function of buffer width. This shape file has no further intent, but is provided as part of the complete data package.
