Can I use a featureset as input to analyze_patterns.interpolate_points?

[DavidJohnson5]

The API guide for interpolate_points for the input_layer parameter mentions "see Feature Input in documentation".  Where do I find that documentation?  More specifically, I'm trying to figure out if I can use featureset as the input layer?  I'm currently getting this error:

FeatureSets are not supported as input to the feature analysis tools.

The following are supported:

• URL to feature layers
• Items of type Feature Layer
• Items of type Feature Collections
• FeatureCollection as a Python dictionary
• FeatureLayer objects
• FeatureLayerCollection objects - the first layer is used.

The 'Feature Input' reference was to Feature input—ArcGIS REST API: Spatial Analysis Service | ArcGIS for Developers  but we should have it a better place in the Python API doc - thanks for alerting us to this.

Thanks Rohit the quick response!.  Would it be possible to construct an in-memory feature layer object from a FeatureSet to use as the tool input?  If not, can you suggest any alternatives for passing in a subset of points from a feature layer to the tool that does not involve creating a new feature layer item?

You can construct an in-memory FeatureCollection object and that will work. The format of FeatureCollection is in the Feature Input page.

[DavidJohnson5]

That works.  Thanks again!

my_featureset = my_flyr.query(where="state='WY'")

from arcgis.features import FeatureCollection
my_fc = FeatureCollection(my_featureset.to_dict())

from arcgis.features.analyze_patterns import interpolate_points
interpolated_points = interpolate_points(my_fc, field='GHI')

All I can say is... "even better" !
