Feature request: interpolation options in extract

[alex-s-gardner]

When using extract to retrieve point values from a Raster it would be useful if the user could specify an interpolation option.

Where would the interp algs come from

Where would the interp algs come from

I think the best option is Interpolations.jl

I just had an idea to do this lower down in DimensionalData.jl. Like have an Interp selector that returns an Interpolations.jl interpolator thing.

You could do thing like rast[X=Interp(x, Spline()), Y=Interp(x, Linear()), Ti=Near(DateTime(2020)))] and it would just work.

Then extract could just call this.

That would be ideal

Was this feature added to DimensionalData.jl? It's something I'd love to use if it's available!

In the meantime I've come up with hack to extract along a line segment where I translate, rotate, and resample my raster so that the segment starts at the origin of the new raster and runs along the X axis and I can pull data from that using the Near selector, but I'm sure that's not the most efficient way.
