Ver 1.0.20 includes:
1) reading and writing files: Sgy, Xtf, Jsf; resize functions for Sgy (set Delay Record Time, Traces End Time, Sample Interval, etc); Magy (G882) files reading;
2) coordinate transformations: utm <-> geographic <-> geocentric;
3) geometrics tasks (minimal distance, segments crossing, normal);
4) create AutoCad scripts with elementary figures;
5) create trackplot (AutoCad script) from folders included xtf or segy files;
6) data (traces) filtration, weighting, gain, etc.;
7) magnetic/gravity modeling (in progress);
8) serial data logging (free pascal);
9) image/matrix sub-horizontal layers handle and auto piking; curves piking tool;
10) cut/merge/resize Tiff with tfw.
