Data Downloads

Data described in this manuscript are available for download and consists of processed GPR data with elevation corrections in JPEG format, and raw GPR data and postprocessed differential GPS data in ASCII format and Keyhole Markup Language (KML). All data and associated formal FGDC data can be downloaded from this publication’s Data Downloads page.

The ASCII GPR data can be viewed with XYZ type packages that can import and image the data. Software programs 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 JPEG images of the GPR profiles can be viewed using standard image viewing software. The navigation data for the GPR profiles are provided in KML or ASCII format and can be viewed using the free Google Earth GIS (Geographic Information System) viewer or ArcGIS Explorer. All navigation data use the projected coordinate system North American Datum of 1983 (NAD83), Universal Transverse Mercator (UTM) Zone 18 North (18N), and all elevations are North American Vertical Datum of 1988 (NAVD88) orthometric heights, and were derived using the GEOID12A geoid model.
