WinLoG can be used to quickly create, edit and print geotechnical, environmental, mining, and oil gas borehole and well logs. The graphical windows interface displays the log as it is changed and shows exactly how the log will look when it is printed. Borehole and well logs can be printed in black and white or color.
The geographical information system feature added in version 4 displays a location map for the project showing the boreholes, cross-sections, and any surface features. This feature makes it easy to visualize your project and can be used to print a location map of the project. To edit a borehole all you need to do is click on it in the location map.
