Description
Recorded survey data from the ground penetrating radar (GPR) survey at the Family Cemetery at Sylvester Manor, Shelter Island, NY. Zipper folder contains raw recorded data. Additional zipped files contain shapefiles for GPR survey transects, total station points, headstone and footstone points, and a Polycam rendering of the survey area.
The .rd7 files are the type generated by MALA GPR systems to record raw data (they are unprocessed binary data files containing the recorded electrical signals), along with .cor (coordinate data), .mrk (markers on radargrams), .mrkj (modern version of .mrk), and .rad (header file; contains survey parameters, antenna frequency, samples per trace, time window, and velocity) files. These are all needed to work with the raw GPR data.
Each shapefile is comprised of seven different file types: .CPG, .dbf, .prj, .sbn, .shp, .shx, and a .sbx file and all are needed for the shapefiles to function. The .shp files are the main files that store the actual spatial data (points, lines, or polygons). The other files contain character encoding (.CPG), shape attributes (.dbf), projection/coordinate system information (.prj), spatial index information for queries (.sbn, .shx, .sbx).
