Hi,

I want to map topographic and bathymetric data on a mesh from two different sources.

- I have points extracted from bathymetric charts for the subtidal zone (I use the 2Dinterpolator)
- I have raster from Lidar survey for the tidal zone.

I don't know how to deal with no data cells in the raster. BK seems to replace the no data value by 0. It is an issue when I map my raster data onto my mesh.

I have a solution which should work but won't be efficient. I can extract with a GIS software my limit no data - data and use this limit as an outline for my 2Dinterpolator. After that, I can map my raster in first and my interpolation in second.

Any ideas?

Regards

That's how I would do it.
