Can you export IDW layers as Vector?

Question

Can you export IDW (Inverse Distance Weighted) layers into vector format?

I've struggled to find a way to do it.

I want to create a mask layer based on a threshold value and can only make a grid layer from it.

Any suggestions would be much appreciated.

Are you talking about creating "filled polygon contours" from the raster surface?

Steve at esri has created some spatial analyst extension tools, one of which does this.

Will try to find the link....

Thanks Dan, but my problem is that it's a large extent area that would require high resolution cells in order to emulates the smoothness of the original IDW... I could chop the data into sections and process it, I guess. I'm probably being to fussy with the convert, to be fair.

But basically, the only way to do this is to export as a grid and then do the raster to polygon with smoothing activated.

It's a shame really, as the IDW visual is vector-like and it's a shame you can't grab that 'visual' and translate it into a real data layer.

You can make a vector layer from an integer grid...ie the indicator grid that I described above.

Explore the help files a bit more ie  ArcGIS Help (10.2, 10.2.1, and 10.2.2)‌

where it indicates that an integer grid is required
