What to do with CPT data?

[JoostGevaert]

The Issue

CPT data is in-situ data, but it has waaay too many data points (e.g. one every 2 cm) to convert all those points to simple feature geometry. This would only slow down rendering and wouldn't really add much data visualization benefits.

An avenue to explore

AGS 4 has three groups for every CPT:

1. SCPG: Static Cone Penetration Tests - General. This contains data about the performed CPT test, like the type of cone used, etc.
2. SCPT: Static Cone Penetration Tests - Data. This contains the CPT data.
3. SCPP: Static Cone Penetration Tests - Derived Parameters. This contains CPT interpretation results. This means that the CPT data has already been split up into columns and possibly soil parameters such as Undrained Shear Strength (Su), Relative density (Dr) or Internal Friction Angle.

The Location geometry for that CPT could then be assigned to the SCPG group, a LINESTRING per interpreted layer could be added to the SCPP group, and no geometry would be assigned to the SCPT group, i.e. the group containing the CPT data.
