We can pass the same options from the grid modules, I've added mask for each of them, that might work?

Yep, mask would definitely work 👍

Now that I look at it we should also rename cellSize to cellSide as we did in the grid modules

Also, I was wondering why was clone introduced in here

var newFeature = clone(gridFeature);
newFeature.properties[property] = zw / sw;
results.push(newFeature);
...
return featureCollection(results);

Clone was used because it mutates the properties, I'm sure there might be a way to remove the clone.

newFeature.properties[property] = zw / sw;

• Change to cellSide 👍
• mask works 👍

Hello, is there any progress with mask parameter? Maybe I'm overlooking some other way to achieve custom interpolation boundary?

Is the mask parameter already implemented? I haven't seen that parameter in documentation.

EDIT: Even though the mask parameter is not mentioned in the documentation, it is there and working properly. But mask option doesn't seem like an option. For example, in below image, I am trying to interpolate 4 points within the polygon (pink background) but I got the values only for the bbox of the input points not for the whole polygon.

Hi @iamtekson. Could you please clarify if this is currently just a documentation issue ...

mask parameter [...] is there and working properly

or an actual problem with the result you get back from the function ...

but I got the values only for the bbox of the input points not for the whole polygon

Or both?

This will be resolved as part of #2444 so the user can pass an optional bbox.
