Common use of Digital Records Clause in Contracts

Digital Records. The airborne data acquisition system will record the following information digitally in a format that enables the recording of each variable over its full dynamic range: GPS time (used as fiducial number ) GPS latitude, longitude or UTM easting, northing and elevation above ellipsoid GPS raw satellite range information Raw magnetic total field (One sensor) Calibrated radar altimeter output Three Fluxgate channels Six Spectrometer Channels (Tc,U, K,Th,Cocmic, and UpU) Spectrometer 256 channel spectrum The base station will record the following information digitally in a format that enables the recording of each variable over its full dynamic range. GPS time (used as fiducial number ) GPS raw satellite range information Raw magnetic total field All survey parameters including raw magnetic total field, electronic positioning, radar altimeter, and time and fiducial markers will be recorded digitally during data acquisition in flight. The magnetic base station will record total magnetic field and GPS time. The data acquisition system organizes the data in a form directly suited to building the processing database. This digital file structure has for each traverse and control line a unique line number and segment number. The base station magnetic profile and differentially corrected GPS coordinates are added to the database using GPS time for alignment.
