Q&A - Question

Currently, only one surface representing DEM in raster format (GRD, TIFF...) is displayed. In locations where one DEM overlays another higher Z value is used. However, this limitation does not include vector formats (TIN for example) - each TIN is displayed separately.

We also need to visualise more than one 3D surface at a time as we would like to see the differences/changes between several DEMs over time. Converting huge raster format DEM to vector format is not an option. 

Has there been any progress on the integration of multilayer DEMs?

Not forgotten. Some work already done. Waiting for a timeslot to be finished

I'm back!  I have been a big supporter of TatukGIS for over a decade and have built many GIS applications using the DK for Delphi.  It is time that Tatuk expand its focus from the surface of the earth into the subsurface. There are an estimasted 32,000 geologist in the US alone, all of which could use your products if you made it easier to peer beneath the surface.

We have a great need to use 3D products to plot and evaluate such things as realtionships of geologic layers, the topography of bedrock, the depth and screened intervals of wells, the concentration and depth of contaminants, the location and shape of the water table, etc.  Much of the date needed to populate these layers are already availabe in the public domain, or are generated by geologists every day. Please allow us to use your products to solve our problems and present our data to the public!

In recent months TatukGIS added support for “geological” 3D maps created from 3D rendering multiple, vertically spaced, DEM layers (i.e., “multiple 3D surfaces”). 3D rendering raster format DEM layers is also possible. There is a bit of information about this new feature in the blog dated Dec. 20, 2019. The functionality is accessed via the visual layer properties control - so available both the Editor and DK products. We might soon offer a more detailed blog about this.

Also be aware of the possibilities for 3D volumetric contouring. Refer to the final image in the blog about grid analysis dated Oct. 6, 2018.

TatukGIS would like to see what you achieve using these TatukGIS supported  functionalities with your geology data!
 

I have a project with 3 layers - a DEM of the Topography, and another with the grid of bedrock elevations (all of which are lower in elevation than the topography).  I also have an aerial to drape over the topography.  I have set both the topography and bedrock surfaces as DEMs.  However, in 3D space, only the highest one in the stack of layers is visible.  For example, if I move the Bedrock DEM above the Topgraphy DEM, the aerial is draped on bedrock, but the topogrpahy is not visible.  If I swtich the order, the aeral is draped on the Topography DEM.  What am I doing wrong?
 

If you are addressing your question to TatukGIS (i.e., it is a product technical support question versus a question to other users), then submit your question by email to support@tatukgis.com, which will create a support ticket.
