First; I see there are some issues regarding the description below, but they are older threads. I want to discuss possible solutions and/or workarounds.
I am currently working with a project within the Oslo (norway) region which has very good TIN photogrammetry. However, at ground level there are relatively large elevation and terrain spike issues. The project is a heliport and the TIN is not precise enough to place my custom made buildings on top of the platform due to very bumpy and pointy terrain.
Due to the default TIN I need to flatten the surface within the platform.
I’ve tried the following methods to adjust the terrain:
-
Placing a polygon with a TIN-exclusion and terraforming to the lowest level.
-
Then I placed a higher priority terraforming polygon ontop to elevate the relevant terrain.
-
The result was terrain spikes, and “uncooperative” terrain which was hard to terraform correctly, and to force to form the way I wanted.
- Placed an TIN-exclusion polygon with terraformin to lowest level.
- Placed a higher priority terraforming rectangle with heigh map (the grid).
- Same result as above.
- Disabled photogrammetry.
- Everything works as expected. No spikes, or other terrain issues.
