Hello,

For a home project I want to 3d print an area from a map.

I have downloaded a geoTIFF file and an asciiGRID file from the Tasmanian governments spacial program "TheList"

The two files are here:

5165244_GeoTIFF.zip - Google Drive

5165244_asciGRID.zip - Google Drive

I have tried for hours using separate programmes, and have found out that I need to use arcGIS, which I now have.

When I try to import the files, I come up with a grwyscale flat plane.

Could anyone walk me through how to create a DEM from these lidar files or point me to a tutorial? I'm frustrated and stumped...

Regards,

Yaro

Are you viewing the tiff in ArcMap or ArcScene. ArcMap is the 2D view; however, ArcScene will display the image in 3D.

Fundamental of displaying surfaces in 3D

Setting the raster layer's base heights using a surface in ArcScene
