I am doing Tilt derivative map.How to get +45 degree and -45 degree contour and depth from it?
, There was a webinar last year about modelling a geothermal prospect. In this webinar Gerry Connard uses Tilt Derivative to calculate magnetic depth to basement solutions as part of the modelling process. He provides a Geosoft script that will determine the distance from the zero contour to +/-45 degree contours for you.
Information on the script file and a link to the webinar can be found in this forum post:
. The part about using the tilt derivative start around 9:43 but it's a great webinar worth watching in it's entirety if you missed it!
Once u get ur tilt map Go to contour and insert the values 0 ; 0.785; and -0.785 in the respective contour lines
There's also an Exploring with Data blog post about it here:
