Surveying, Setting Geometry, and Mapping
Setting geometry is the act of creating headers that include the locations of seismic sources and geophones. BSU includes programs for setting geometry as well as making maps and computer aided drafting (CAD) files from headers once they are set.
- GENWAW 10.1.1 Labor intensive interactive conversion of SEG-2 (*.DAT files) and setting geometry for each source and receiver.
- GENREF 10.1.2 interactive, generates bash scripts for setting geometry on CDP reflection shooting. Bison data ONLY.
- TOPCON 10.1.3 reads a survey *.nez file and Bison seismograph file, creates *.xyz file.
- BHED 10.1.4 down-load or up-load header data from or to an *.seg file.
- TOPCON2 10.1.5 converts SEG-2 (*.DAT) to *.seg format while setting geometry from command line arguments. GENVSP 10.1.8 can be used first to set up bash scripts that use a *.nez file and calls to TOPCON2.
- GENSETG 10.1.6 interactive program creates files for setting geometry where phones fixed, shots move (reciprocal shooting)
- SETGEOM 10.1.7 Run after GENSETG, takes the shot.txt, phones.txt, and *nez files created by GENSETG and applies them. A *.nez file is Northing, Easting, Elevation text file.
- GENVSP 10.1.8 interactive program for setting geometry in down-hole surveys.
- GENBHOD 10.1.9 SH-wave source interactive program generates bash scripts to determine down-hole tool orientation by principle component analysis (PCA) of shot records. Program BHOD 10.1.11 does the actual PCA.
- GENBHODV 10.1.10 Vertical impact source interactive program generates bash scripts to determine down-hole tool orientation by PCA. Experimental, uses Rayleigh wave on horizontal component. Program BHOD 10.1.11 does the actual PCA.
- BHOD10.1.11 performs PCA on down-hole data.
- BNEZ 10.1.12 generates a *.nez file from rules. Typically run twice, once for shots, once for geophones.
- TOP2NEZ 10.1.13 converts a raw Topcon Total Station survey file to NEZ format.
- TOP2DXF 10.1.14 reads a *.nez file and converts it to a *.dxf (CAD) file.
- TOPBCRD 10.1.15 applies rotation and translations to coordinates in an *.nez file. Program BCRD 10.1.16 does this on *.seg files.
- BCRD 10.1.16 rotates and translates header geometry coordinates in an *.seg file.
- BCAD 10.1.17 creates a CAD *.dxf file from *.seg file headers.
