Create terrain from AW3D Standard

Grasshopper Gismo

I received sample data from AW3D at 5m resolution (5m DSM Level-1, 5m DSM Level-2, 5m DTM) and also at 2.5m resolution.

The 5m DSM Level-1 comes as two TIFF files. ImageMagick tells me:

$ identify *.tif
N32377E130545_N32165E130758_LT_DSM_5m_EL.tif TIFF 5101x5101 5101x5101+0+0 16-bit Grayscale Gray 49.709MiB 0.010u 0:00.004
N32377E130545_N32165E130758_LT_MSK_5m.tif TIFF 5101x5101 5101x5101+0+0 16-bit Grayscale Gray 49.709MiB 0.000u 0:00.004

How do I convert these into terrain?

I have used Gismo successfully to create terrain. It downloads terrain data via Opentopography. But I have not found an option to specify my own files. The description of at least one Gismo component mentions that terrain can be created with Ladybug. I have installed Ladybug, but again I’m lost.

Hi @feklee

You can use the import topo from Heron. You have to download it from the package manager.

Hi @feklee
Indeed Gismo does not have component to load custom terrain files. It can generate automatically a terrain for defined location/address and radius.
The functionality to open a terrain file is actually possible via Gismo’s “Terrain Generator” component’s source code. But I still haven’t exposed it as a new Gismo component.

The mentioned Ladybug component which also creates terrain based on location is Ladybug “Terrain Generator” from here, made by @AntonelloDN.
