Online_Linkage: http://pubs.usgs.gov/sir/2012/5290/ Description: Abstract: Marsh surface points surveyed in July 2010 at 20 marshes in the Acadia National Park area. Each point references a wooden stake installed at the marsh surface. Elevations of these points are accurate to +/- 2.5 centimeters (cm). These points were used to determine the root mean squared error (RMSE) of the LiDAR data in this study area, and the 95 percent confidence intervals. Purpose: Marsh Points were used as part of independent accuracy assessment of LiDAR data at salt marsh surfaces. Five surveyed points at each of the 20 marshes were used for LiDAR elevation accuracy assessment. Each of these points is located at a wooden stake pounded into the marsh surface and flush with the marsh surface. Supplemental_Information: Geodatabase product of a USGS study funded by National Park Service Climate Change Response funding, NPS PMIS # 161531, "Inventory and Protection of Salt Marshes from Risks of Sea Level Rise at Acadia National Park, Maine", 2012. The database layers are collectively termed "appendix 1" of the USGS SIR report. Database layers included in appendix 1 include: Surveyed benchmarks used in surveying exercise (SIR2012_5290_ACAD_SurveyedBMs); Surveyed marsh points used for quality control for LiDAR data (SIR2012_5290_ACAD_Surveyedmarshpoints); Surveyed elevation reference marks for each surveyed marsh (SIR2012_5290_ACAD_SurveyedERMs); Salt marshes inventoried for this study (SIR2012_5290_ACAD_Saltmarshpolys); Inundation lines for each marsh under 60 cm of sea level rise (SIR2012_5290_ACAD_Inundationlines); Potential barriers to migration of salt marshes (SIR2012_5290_ACAD_Potentialbarriers). The inundation lines presented are in no way a prediction of whether marsh migration will actually occur, only indications of where land will be inundated and would therefore be available for migration under 60 cm. of sea level rise.

Logical_Consistency_Report: Data are internally consistent. Completeness_Report: The data are complete. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Surveyed point data solved using total station (TS) data relating ERMs to MPs. The Sokkia TS provided 5-second angular precision and millimeter-scale precision in both distance and elevation with shots up to 1 km distance depending on atmospheric conditions. Potential errors were controlled by resurveying if survey loops did not close to less than 2 cm. Horizontal positions considered accurate to +/- 2.5 cm.

Process_Step: Process_Description: Marsh points were located on flat terrain within each marsh with a minimum spacing of 10 meters (m) between points. Control point elevations were surveyed relative to nearby ERMs using a Sokkia Set 4B Total Station (TS) infrared laser transit and survey rods with retro-reflectors (prisms). Survey data provided the horizontal and vertical positions of these points. Process_Date: 2010 Process_Step: Process_Description: X, Y, and Z coordinates from the survey data were put in a text file and imported into ArcGIS and saved as a shapefile.
