was able to connect a geo-tiff to my map. Can someone tell me how to "track" elevations? Just want to display or list the elevations as I move the cursor. Thanks

Hi,
there is no objectsnap, even no geometry you have when displaying a raster-dem like model. So there is also no option to get the elevation at specific points directly.
What you can do: you can create contour lines from your tiff, these are stored into a SDF, that will give you geometry and so you can get elevations from that contours/points on contours.

I too fear there's no way to get that in Autocad, while it's automatic in a free software like Qgis, sir.
Hello from France
With ACAD MAP (since Release 2008 maybe 2007) you can create elevation contour from ESRI Raster Elevation files : .ASC files in fact
Sorry I don't know if it's possible also from GeoTiff !?
Here a nice french tutorial to generate elevation contour from ESRI .ASC files :

I hope you can follow the tutorial even if you are not French !?

Hi,
>> how do i create contours in autocad map from the image?
In the task pane of Map 3D (command _MAPESPACE) right-click your DEM layer ==> there you find the option to create a contour layer.

Hello Alfred
YES I am a "poor stupid" boy !
I am using often this feature (since a long time ago) but only with ESRI .ASC Files !!
And the french tutorial says >>>
En résultat, vous obtenez l'affichage de votre MNT.
Ce MNT peut être dans les formats GeoTIFF, Esri Grid Ascii (extension .asc), Esri Grid Binaire <<<
Thanks to open my eyes !!

Hi,
>> how could I raise that DEM by a multiplication factor of 3.28
I created a video that shows how to create contours from DEM and as a second step how to scale the elevation of the contours.
Let me know if you have additional questions to that.
