This software was initially developed for conversion of trace header coordinates in segy files , but it has grown significantly and now offers much more. Versin 3.1 offers some new features and improvements: Completely redesigned Datum Converter module. Datum Converter now supports over 200 datums and 7 different projections New Reformat, Add, Multiply module for reformating and editing headers in multiple files. Machine ID is no longer sensitive to connected USB harddrives. No need to disconnect USB hardrives before starting segy toolkit software. Read only files can now be viewed using header viewer. Files can be accessed directly from CD or DVD. Currently Seismic Toolkit contains following modules: Seismic Datum Converter. This module enables conversion of segy files trace header coordinates between different UTM zones and/or between different geographical datums. Currently over 200 datums are supported. 7 projections can be used in datum transformation. Currently supported projections are: UTM, Transverse Mercator, Albers Equal Area Conic, Lambert Conformal Conic (1 parallel), Lambert Conformal Conic (2 parallels), Mercator, New Zealand Map Grid (NZMG). Multiple files can be selected. Segy Coordinates Writer. This module enables writing of coordinates to segy trace headers. Coordinates are read from ascii navigation file and written at specified header location. Software performs necessary interpolation or extrapolation of coordinates. Multiple files can be selected. Trace Header Viewer and Editor. This module enables viewing of trace headers in four different formats (ibm float, ieee float, 32 bit integer, 16 bit integer). Headers can be edited and values of headers written back to segy file in any of these formats. Interpolation of headers is also possible.Values of the header in any of these formats can also be displayed on graph. Ebcidic and binary header editors and viewers are also available.
