Geoplot 4.0 - Latest Code - Matrix USB dongle protection ONLY


The latest Geoplot 4.0 version available is Build 1322 and will only work with Matrix USB dongles. Check which version of Geoplot 4.0 you are using by selecting About Geoplot from the Help menu. Please note that only Matrix USB dongles that have been upgraded to run Geoplot 4.0 will work with this code and there is a charge for this upgrade. Dongles are upgraded remotely using an executable file sent via a DropBox link; the upgrade is specific to an individual dongle. Once upgraded the Matrix USB dongle will allow you to run both Geoplot 3.0 and Geoplot 4.0. The download is a zip file which should be unzipped and the component parts can be either burnt to a CD or stored in a temporary directory from which Geoplot 4.0 can be installed. The installer includes code and Geoplot 4.0 instruction manual.

Geoplot 3.0 - Version Information


Version 3.00v

Bug fix for a data array problem that occurred when very large sized grids have a very small sample interval. A bug has been discovered in Geoplot 3.0 when collecting '2 Parallel Twin' data with a traverse interval of 0.5m or smaller. A workaround is to download the data as two multiple data sets then use the Merge facility on the File menu to combine them.


Version 3.00u

For Matrix USB and Matrix LPT Hardware Lock protected versions only - NOT for Az-Tech LPT Hardware Lock Protection or Software Lock Protection. Merge facilities are now provided for combining MSP40 alpha and beta data sets whilst retaining data crispness. A Help panel has been added to provide guidance on importing non-standard data sets. Code changes have been made to provide Vista support. This overcomes printing problems in earlier versions by providing an optional means to omit display of the Printer Dialog Form. See Running Geoplot 3 on 64 bit Platforms for further details.


Version 3.00t

For Matrix USB and Matrix LPT Hardware Lock protected versions only - NOT for Az-Tech LPT Hardware Lock Protection or Software Lock Protection. Animation facilities have been added to the Graphics menu. This allows different views of one data set, or indeed several data sets from different instruments over the same area, to be visually compared. A Wallis filter has been added to the Process Toolbar and Process menu. This provides histogram equalisation that emphasises low value readings and compresses high value readings. Data can now be exported in spreadsheet format. Pseudo-section data can be exported in Res2dinv format. This third party program provides inversion facilities using the least mean squares method and is available for free download in a limited functionality demo version. Download facilities for the new Geoscan Research MSP40 Mobile Sensor Platform have been added. A Shift facility has been added for dealing with alpha and beta data from the MSP40. The Merge Comp facility has been extended to include Grad601. The scope of some functions on the Edit menu has been extended.


Version 3.00s

Internal maintenance code changes relating to Matrix dongles. Matrix USB dongles that are HID compliant start shipping after serial number GP05698.


Version 3.00r

Support for Matrix dongles (USB and LPT) introduced. For Matrix USB and Matrix LPT dongles versions only: Periodic Filter allows entry of a band of frequencies, not just one frequency. Environment Options provides a setting that allows for correction of the vertical position of the side toolbars which can be misplaced in 2000 or XP.


Version 3.00p - latest version for software protection and Az-Tech LPT dongles

Master Grid now allows you to insert rows and columns. It also now allows you to quickly add either 'a' or 'b' at end of names in a previously created master grid making it easier to create matching dual FM256 composites for merging. Additionally, you are no longer required to have matching directories for Master Grids and data Grids for composite creation. Interpolate (Shrink) now has provision for shrinking data by straight line deletion, not just averaging. Odd or Even lines can be specified. This makes it possible to investigate the effect of different sampling strategies using already highly sampled data. Destagger can now operate on all grids in one pass. It can also be set to either destagger alternate lines (-2-4-6-8) or destagger in pairs of lines (- - 34 - - 78) which can be required when a dual system is turned through 180 degrees with zig-zag surveying. It is also possible to destagger individual lines. All Save and Save As forms now have a 'New Directory' button for easier creation of new directory structures within the form. Code has been modified to allow printing to file. The Graphic Plot Details panel to the right hand side of the main screen is changed from a white to grey background. Fixed grid rotation bug.


Version 3.00k

Added Merge Composite code for 180 degree rotation of CF6 carrying frame.


Version 3.00h

Provision made for downloading FM256 gradiometer data. Merge Composites facility added to File menu. Added threshold facility to Zero Mean Traverse, Spectrum and Periodic Filter. Fixed bug in Deslope and created new splash screen.


Version 3.00g

Added Swop Adjacent Traverse to Edit menu to provide striping correction for MPX15 data. Changed error messages for RS232 downloads. Made floating Statistics form border fixed.


Version 3.00f

Added import of spreadsheet data with either comma or tab separation.


Version 3.00e

Modifications made to Software Authorisation system.


Version 3.00d

Modified download error messages for framing and parity.


Version 3.00c

Added educational network version with limited functionality. Fixed process area selection problem. Fixed Destagger bug and included shift of dummy readings as well.


Version 3.00b

Code added to check if a network user was already logged on.


Version 3.00a

Red text added to rotate composite and download forms. Underlying code for individual network user options added.


Version 3.00

Original shipment code.
