Geosoft File Format

When exchanging data with Geosoft / Oasis montaj for UXO projects, the data files are ASCII text files that contain one or more of the following sections:

VSP Transect Design Parameters

This section contains all the data necessary for VSP to create a transect spacing design, including saved UXO power curve graphs. The first line of the section is:

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-DESIGN-PARAMETERS-TXT ^^^^^^^^^^!!!!!!!!!!

Followed by the line:

DesignParameters.Version 0

The last line of the section is:

DesignParameters.End

A complete description is not presented here and may change in future versions. To see the contents of the section, select File / Export / to Geosoft from the menu, check the VSP Transect Design Parameters box and press the Export button. Examine the exported file using any text editor (such as Notepad).

Sample Areas

These sections contain the information about the Sample Areas in VSP. There are two different types of Sample Areas sections: Clear Text and Hex-Coded SHP file.

The Clear Text section stands alone and begins with:

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-AREA-TXT ^^^^^^^^^^!!!!!!!!!!

Following that are lines of text that describe the units, colors and points that compose the Sample Area polygons.

The Hex-Coded SHP (labeled Shape File Compatible on the dialog) sections appear as the triplet of sections:

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-AREA-SHP ^^^^^^^^^^!!!!!!!!!!

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-AREA-SHX ^^^^^^^^^^!!!!!!!!!!

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-AREA-DBF ^^^^^^^^^^!!!!!!!!!!

These sections correspond to ArcGIS SHP, SHX and DBF files. These sections actually contain thc ose 3 files encoded as hexadecimal text.

The first line of text in the section contains the number of bytes in the file.

Following that are lines of hexadecimal digits, two digits per byte. VSP formats the lines to contain a maximum of 64 characters (32 bytes).

The three files contain the information about the Sample Areas in VSP.

Designed Transect Locations

These sections contain the information about the Designed Transects in VSP. There are two different types of Design Transect sections: Clear Text and Hex-Coded SHP file.

The Clear Text section stands alone and begins with:

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-TRANSECT-TXT ^^^^^^^^^^!!!!!!!!!!

Following that are lines of text that describe the width, units and end-points of the transects that have been designed by VSP.

The Hex-Coded SHP (labeled Shape File Compatible on the dialog) sections appear as the triplet of sections:

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-TRANSECT-SHP ^^^^^^^^^^!!!!!!!!!!

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-TRANSECT-SHX ^^^^^^^^^^!!!!!!!!!!

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-TRANSECT-DBF ^^^^^^^^^^!!!!!!!!!!

These sections correspond to ArcGIS SHP, SHX and DBF files. These sections actually contain those 3 files encoded as hexadecimal text.

The first line of text in the section contains the number of bytes in the file.

Following that are lines of hexadecimal digits, two digits per byte. VSP formats the lines to contain a maximum of 64 characters (32 bytes).

The three files contain the information about the Designed Transects in VSP.

Surveyed Transect Paths

These sections contain the information about the Course-Over-Ground (COG) Surveyed Transect Paths in VSP. There are two different types of COG sections: Clear Text and Hex-Coded SHP file.

The Clear Text section stands alone and begins with:

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-COG-TXT ^^^^^^^^^^!!!!!!!!!!

Following that are lines of text that describe the width, units and survey points that have been loaded into VSP.

The Hex-Coded SHP (labeled Shape File Compatible on the dialog) sections appear as the triplet of sections:

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-COG-SHP ^^^^^^^^^^!!!!!!!!!!

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-COG-SHX ^^^^^^^^^^!!!!!!!!!!

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-COG-DBF ^^^^^^^^^^!!!!!!!!!!

These sections correspond to ArcGIS SHP, SHX and DBF files. These sections actually contain those 3 files encoded as hexadecimal text.

The first line of text in the section contains the number of bytes in the file.

Following that are lines of hexadecimal digits, two digits per byte. VSP formats the lines to contain a maximum of 64 characters (32 bytes).

The three files contain the information about the Surveyed Transect Paths in VSP.

Anomalies Identified

These sections contain the information about the Surveyed Target (Anomalies) in VSP. There are two different types of Target sections: Clear Text and Hex-Coded SHP file.

The Clear Text section stands alone and begins with:

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-TARGET-TXT ^^^^^^^^^^!!!!!!!!!!

Following that are lines of text that describe the number of files, map units, number and locations of Targets (Anomalies) that have been loaded into VSP.

The Hex-Coded SHP (labeled Shape File Compatible on the dialog) sections appear as the triplet of sections:

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-TARGET-SHP ^^^^^^^^^^!!!!!!!!!!

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-TARGET-SHX ^^^^^^^^^^!!!!!!!!!!

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-TARGET-DBF ^^^^^^^^^^!!!!!!!!!!

These sections correspond to ArcGIS SHP, SHX and DBF files. These sections actually contain those 3 files encoded as hexadecimal text.

The first line of text in the section contains the number of bytes in the file.

Following that are lines of hexadecimal digits, two digits per byte. VSP formats the lines to contain a maximum of 64 characters (32 bytes).

The three files contain the information about the Targets (Anomalies) in VSP.

GIS Projection Information

This section contains the projection data that may have been loaded from an ArcGIS PRJ file. The first line of the section is:

!!!!!!!!!!^^^^^^^^^^ VSP-UXO-PROJECTION-TXT ^^^^^^^^^^!!!!!!!!!!

The second line contains the contents of the PRJ file that has been loaded into VSP.
