Sample reports

 

Using our innovative "Correlation with Depth" feature, user can plot the variation of the correlated soil parameter along the depth of the borehole which enables compaison of different methods. By using soil filter feature, user can hide those correlations which are not related to the soil type at a certain depth. To try a full feature version of NovoSPT please download the program here.

 
NovoSPT is available in English, Spanish, Chinese (Simplified), Turkish and Farsi languages.
