How can I geo-reference and digitize features on a Y,Z plane of a vertical cross-section in ArcGIS? The surface coordinate system is NAD 83 UTM 15. This is a simplified version of the question found here: How to digitize directional drilholes from scanned vertical sections?
(can be negative=underground vaules)
Finally >> Convert to 2D Polyline
After disappointing results in other software packages, I created a workflow to build geology cross sections with the ability to display deviated and inclined downhole data, and digitizing lithology contacts in ArcGIS.
I am now re-mapping downhole surveys to view the data in East to West and South to North sectional views. (When importing points map X = Y and Y = Z and using unknown coordinate system set to metres for unit.) Adding 3D DXF subsurface objects is a bit tricky but after converting these models to point clouds and adding XYZ coordinates (I densifying the 3D mesh lines to get more contact points to digitize from) I can the remap the XYZ and query for a range of easting or northing values (however the section is oriented). This gives me a selection of points on the perimeter of the contact. I had to create (and will create more to automate the process further) a few add-ins. 1. to convert mesh lines to 3D points using al vertices, 2. creating a coordinate grid i can use on the sections. (Northing, Elevation)
It's not the most dynamic process but afer i write a few tools for updating new drillholes it will hopefully get easier.
