Saint PetersburgFL33701USA727-803-87479 AM - 4 PM, M-FContact the USGS.Initial classification of Assateague Island was made by Dr. Robert A. Morton and Brian Cooke using historical photography, 1999 and 2003 aerial photography, and published National Park Service classifications of Assateague Island. Layers were roughly drawn in a mosaic-like manner such that barrier core was the background layer and all other layers were drawn on top of it.ESRI ArcGIS 9.12004-2005Jeremy E.

There were many mistakes, mis-referenced layers, and 2003 aerial photography became available. All data layers were imported into a Personal Geodatabase. A topology that included all the layers making up the Assateague Island geomorphic map was created and an extensive rule set was generated to enable the use of ArcGIS topology tools to find and fix overlapping regions and other problems. After all overlaps were addressed, layers were referenced to more recent data and errors in the original classification were addressed.ESRI ArcGIS 9.2March 2007 - July 2007ESRI ArcGIS 9.2Jeremy E.

Saint PetersburgFL33701USA727-803-87479 AM - 4 PM, M-FContact the USGS.Extraneous attributes were removed and all layers were exported from the Personal Geodatabase.July 2007Both 'Shape_Length' and 'Shape_Area" attributes were inherently generated and calculated by the ESRI ArcGIS Personal Geodatabase these layers were edited in. They should be accurate to 0.01 meters.Due to these data being created from multiple sources including aerial photography from 1999 and 2003, elevation data from lidar surveys, older NPS classification maps and shapefiles, and historical photographs, some areas will be more accurate than others. While most of the data is referenced to 0.25 meter resolution aerial photography taken in 2003 and EAARL lidar surveys taken in 2003 and 2004, some areas were not updated from lower resolution aerial photography taken in 1999.This shapefile is part of a 17 layer series and only contains areas classified as accretion mounds.The sources of data used to delineate the map unit boundaries were 1999 National Park Service aerial photographs (0.76 m resolution), 2003 National Park Service aerial photographs (0.25 m resolution), 2003 and 2004 joint NASA/USGS lidar elevation surveys (1 m horizontal resolution), and a vegetation map provided by the National Park Service (10 m resolution). Most of the map boundaries of the classification units were referenced to the 2003 aerial photographs.
