I have a raster elevation model above sea-level and a point feature class for the bathymetry in fjords and ocean, with quite varied density of the points.
Any ideas on how to combine the information from both datasets into one new raster layer containing elevation information above and below sea-level?
I am running arcmap 10.2 with spatial analyst and 3D analyst toolboxes.
many options...which give rise to questions
back to you...
Hi Dan,
Thanks a lot for your answer that got me on track for a solution.
I have now solved the problem using an inverse distance algorithm.

Jane as Dan mentioned there are many things to consider, I tend to use different algorithms / interpolations until I find one that fits "best". There are many parameters and variables you can play around with ... have a play to find what you need.
There is also a merge tool for rasters. I'd be careful of any overlap here though, so probably best to ensure that they don't overlap.
