Data Downloads
Data described in this Data Series Report are available for download and consist of processed GPR data with elevation corrections in JPEG format, raw GPR and postprocessed differential GPS data in ASCII format, and Keyhole Markup Language (KML). All acquired data and associated formal Federal Geographic Data Committee (FDGC) data can be downloaded from this report’s Data Downloads page.
The ASCII GPR data can be viewed with XYZ-type packages able to import and image the data; software such as MathWorks Matlab R2015a (http://www.mathworks.com/products/matlab/), Reflexw (http://www.sandmeier-geo.de/reflexw.html), and GNU Octave (https://www.gnu.org/software/octave/) are recommended. The GPR JPEG images can be viewed using standard image viewing software. For the shore perpendicular lines (run west to east), the west is on the left side of the image, and for the shore parallel lines (run north to south), the south is on the left-hand side. Navigation data for the GPR profiles are provided in ASCII format, or as KML files, and can be viewed using the free ArcGIS Explorer or Google Earth Geographic Information System (GIS) viewers. All navigation data use the projected coordinate system North American Datum of 1983 (NAD83), Universal Transverse Mercator (UTM) Zone 18 North (18N); all elevations are North American Vertical Datum of 1988 (NAVD88) orthometric heights, derived using the GEOID12A geoid model.
