Plot Volume of insufficient data

Question

0 个投票

Hi,

I would like to plot a 3d model of a reservoir.

I have the following data:

Surface Area for 2 different Water Levels (Lat/ Long - Coordinates)
Thalweg of the Reservoir (Lat/ Long - Coordinates)
An Excel-Sheet with correlating data for the Elevation [m a.s.l.] - Capacity [km³] - Surface Area [km²]

Is there a possibility to calculate a 3d model of the above mentioned data?

where does the insufficient data come into the picute, what does Thalweg mean and was is [m a.s.l.] mean? And what do you mean by "model".

in terms of volume, convhulln can calculate it, but you might need to do an isosurface to identify the point on the boundary of the region with insufficient data, and then pass only those points to convhulln.
