Lynx Exploration Archivist
Lynx Exploration Archivist Map Scanning and Vectorising (LEAMAP) software is a comprehensive package for converting hard-copy seismic line location (shotpoint) maps into digital data, and importing and editing existing location data from a variety of formats. Using the utilities provided in the package, output files can be made ready for loading to seismic interpretation workstation or further processing.
LEAMAP can be used as a standalone system, or can be integrated with LEASSV to provide a full and comprehensive solution for reconstructing seismic data from images of sections and basemaps.
Minimum hardware requirement is a PC with Intel compatible CPU running Microsoft Windows 98, ME, 2000 or XP. Over 60 raster file formats are supported via Snowbound Software Inc's raster library. Plotting is supported via standard Windows printer drivers.
Programs contained in the package are accessed from the Lynx Launcher, a program manager which allows all installed Exploration Archivist programs to be accessed from the Lynx desktop icon. Installation can be from CD-ROM, or from install files downloaded from this website.
The LEAMAP package contains:
LOCDIG enables seismic shotpoint location and cultural data to be digitised from a scanned image of a basemap. The main features include:
The screenshot above shows digitised seismic locations overlaid on the input scanned basemap.
LOCDIG implements advanced calibration using a triangulated network, allowing digitising of warped, spliced and badly scanned basemaps. The number of calibration points you need to use usually reflects the quality of the input basemap.
The screenshot above shows the calibration grid (green) overlaying the raster image. The calibration point (red cross) is being edited, to adjust the XY world or pixel coordinates.
LOCCONV will import seismic location data from text files and CSV files, and output Lynx LOC files. Seismic location data is usually transferred as some sort of ASCII file containing a number of coordinate records per seismic line. Each record usualy contains the line name, shotpoint number, XY coordinate and/or lat/lon coordinate. The format of these files varies enormously. This utility has a flexible field definition to allow you to specify how to convert these files.
LOCCONV also reads 'standard' UKOOA and SEG-P1 location files in EBCDIC format.
A wizard-style interface leads you through the conversion.
The screenshot above shows data columns from the input file highlighted in the preview window.
LOCPREP is an interactive editor for Lynx and UKOOA type location files, which store seismic shotpoint location information, and can also store general location information. You can use LOCPREP to perform a variety of tasks with LOC files, including the following:
The screenshot above shows a seismic line selected and ready for editing by choosing one of the options on the lower toolbar.
LOCDUMP allows Lynx LOC and UKOOA/SEG-P1 files to be viewed as ASCII text. Lynx LOC files cannot usually be viewed in standard text editors, because the records have no delimiters. This program formats the file for viewing as if is was a regular MS-DOS text file, useful for diagnostic purposes.
BASEVIEW is a viewer for seismic location data in Lynx LOC and shapefile formats. You can edit the display parameters for line names and shotpoint annotation, and print full-scale maps to Windows printers and plotters. For more information see Lynx Baseview.
Additional utilities are also optionally available for the following tasks:

To run the software, a licence is required from Lynx, in the form of an activation file or hardware key.
