Depth inacurate in DEM
« on: February 14, 2023, 05:26:43 PM »
I have a model of the ocean floor on a local coordinate system. I have inputted that point 1 is 11.3m depth and point 2 is 12.7m depth. Both of these markers are on the sea floor. When I create a DEM, it is showing that where point 1 would be is ~3m and where point 2 would be is ~10m. Clearly, those numbers are incorrect. Does anyone know why the program may be doing this, even though I have inputted the depths? Screenshots of the dense cloud and DEM included.
Thanks in advance!

Try negative values. -11.3 instead of 11.3
