I'm an experienced ArcGIS Pro user, but completely new to geotech and the 'Geostatistical Analyst' toolbox (for which we have not yet purchased a license).
I would like to use the 3d interpolation tools in the Geostatistical Analyst toolbox to generate 3d models from geotechnical works performed by contractors. The interpolation tools require a feature layer as input, which must be a 3d point layer with an attribute to be interpolated. I have two questions around this input layer...
- Our geotech contractors who perform borehole investigations do not usually supply us with spatial data like this. What sort of data formats are geotech contractors used to supplying that I could easily convert to this? (Eg, CSV/Excel?) Ie, what should I ask for that would be understood and accepted?
- When they supply such data, it is the elevations where the strata changes within each borehole which is critical (eg, from soil to clay, from clay to bedrock). However, a point would have just one such strata type attribute value, I guess (either soil, or clay or bedrock). How would this be managed in such a dataset? Is this done by generating two points at almost the same location? Eg, a soil point 1mm above a clay point, and a lower clay point which is 1mm above a bedrock point? Or another way of looking at it would be... 2 points for each strata type (per borehole), one for the top of the clay layer and one for the bottom of the clay layer.
Thanks for any insight you can provide for a geotech newbie.
