GEF-Verification is part of the GEF-viewer. It can be used to verify whether files comply with the GEF-CPT-Report format. Verification consists of checking for syntax errors and contextual inconsistencies in digital CPT-files using the GEF-CPT-Report format. The software opens a GEF-file and performs a verification. A log of the errors that are found is given. Verification of GEF-files in batches is also possible.
In September 2002 the program has been updated, version: 1,1,0,0. It is now compatible with GEF-CPT-Report 1,1,0. Read readme.txt for installation. Download the program (340kB, 2003-05-23). 

GEF Library

  • gef2.dll
    The old GefLibrary.dll is no longer supported. It has been replaced by gef2.dll. In the meantime a new version has been prepared: 3,1,1. You can download the dll via the file gef2dll.zip. This archive contains, next to the dll, a file that explains what has been changed and added. (version 3,1,1; date 2007-10-02)
  • Programmers documentation
    In order to simplify the use of the dll, a programmers documentation has been prepared. Furthermore include files and an import library for Visual C++, a unit for Delphi and the function definitions for Visual Basic have been added, as well as sample files in these languages, which we hope will inspire the programmer. The documentation of the functions has been brought up to date with gef2.dll version 3.1.1. The document with the info on the functions in the GEF2.DLL can be downloaded. (date 2007-10-21)
  • Error handling
    Ideally GEF files should not contain errors. In the common day practice errors or omissions are introduced. The way application programmers should handle such errors, is explained in adocument.. This document has been integrated into the programmers documentation.

 

NENGEO conversion tool

The NENGEO-format has been used since years as a standard format for CPT's in the Netherlands. If you are running Windows-XP, it is possible to convert a file in the NENGEO-format to GEF-format and vice versa by means of the GEF-NENGEO-converion tool.

  • Copy the file nengeostekker.zip (300 kB, 2006-07-06) to a directory of your choice and unzip the .zip file.
  • Create a short-cut to the file runner.bat. This file can be found in the subdirectory bin, which has been created during extraction.

The conversion tool has been written in Java. In order to run the tool, you must install SUNs© java runtime engine; you can download it via SUN©s website. On the SUN© website you must choose 'Windows Off line' (situation: November 2006). First of all: DO read the installation instructions. Alternatively you can download SUN©s file jre-1_5_0_08-windows-i586-p.exe. Note: you must login on your PC as a (local) administrator in order to install the java runtime engine on your PC.
