lidar data as elevation source
Hi, I would like to use lidar data as elevation source.
I have tried first to create a tpkx file using "Create Map Tile Package" tool in ArcgisPRO.
It doesn't work when I use it as elevation source for my ArcGISmap in Unity (and it is only few Ks?!??). Here is a drive link to the lidar data and tpkx:
I have tried also to host it using in ArcGIS online. It doesn't work when using the link as elevation source either.

I'm wondering what I did wrong ?!?? and if someone can help me with that?
Thank you ! Merci beaucoup!
Hi Matt,
I work with mbd on the same project.
Our goal is to create a DEM with vertical exaggeration, then convert it to tpkx.
After unsuccessfully trying to create a tpkx with « Create Map Tile Package » (post of mdb), I opened my dem in ArcGIS Pro, in a map, as a Elevation surface (ground). I right clicked and chose Share as web layer, and and I was able to upload it on my ArcGIS online. This elevation works in Unity. And when I download the tpkx, it also works.
For this test, I used DEM « MNA_20K » from Gouvernement du Québec, and I used « mosaic to new raster » to create one large DEM, without vertical exaggeration (if you want to reproduce, you can take de f22c07_XXXX files). https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Matriciel/Elevation/Local/MNA_20K/Grid/
Here is the url of my elevation layer on ArcGIS Online
https://tiles.arcgis.com/tiles/J6AQcFJqZURZKQVP/arcgis/rest/services/mna_20k_riki/ImageServer
and the tile package

My second test is to apply vertical exaggeration to the DEM. I managed to do this using the Raster Calculator tool (spatial analyst tools / map algebra). However, I am unable to upload it to ArcGIS Online. The operation fails, and I don't have any details.
So the questions I ask you:
Do you know why am I not able to upload to ArcGIS online the DEM resulting from a raster calculator.
And can you help me to create a tpkx with my data, without going through ArcGIS Online? Because I want to use other lidar-derived DEMs, which is much heavier than MNA_20K. I know ArcGIS, but the tpkx, schema tiling, caches, etc… are new for me.
Thank you very much!
Marie
