This page is used to add, edit or delete boreholes. You start by adding boreholes, one in a row, in the table at the top of the page. Please note that borehole data requires coordinates (local or UTM datum) but the program uses neutral units system:


 


All input data in VisLog are unit-neutral; However, depth and coordinates of a borehole must be in the same units system. Remember that VisLog only deals with presentation of your data and no interpretation or data-manipulation is performed.

Manual Data Entry

To enter a new borehole click on "Add new borehole" button on toolbar; a new empty row will be added to the end of the boreholes and soil layers table. Please enter borehole data in the new row and then enter soil layers of the borehole and test data on corresponding tables.  

Import From Text File

If you have already stored the boreholes data in a Text file, you can easily import them (using the yellow folder icon on top-right corner of tables) into VisLog . Please read The Import from File help page for more information. If your data is entered in an Excel file, save it to Text format and then import it to VisLog.


 VisLog has a feature to import borehole data directly from gINT project files and from NovoLAB database.

 

 Test data can be any type of test performed in a borehole including SPT, CPT, Moisture Content, Vane Shear, Shear Wave Velocity, etc.

Coordinate Adjustment

Use the tab located below the borehole table to manipulate coordinates.

Geocoding

This feature requires UTM coordinates of boreholes. Read more about geocoding in this article.

 

 VisLog supports all soil classes defined in Unified Soil Classification System (USCS). For visualization purposes when you select a Soil Type from the drop-down list, VisLog automatically finds the Soil Group that it is associated with. Subsequently, the Soil Group color is used for visualization and drawing the soil profiles. To see how to manage Soil Grouping please read this article.
