Elevation Profile Does Not Return Z or M Values

Moe-Notos

I am attempting to retrieve an elevation profile for a local feature through the Python API.

While the job executes successfully, the output does not contain any Z or M values (see below).
I have explored several approaches, such as loading in the toolbox manually, as well as attempting to find some place to specify returnZ = True.

Please advise how Z and M values could be retrieved.

Thanks in advance!

 

Code:

from arcgis.features.elevation import profile
from arcgis.features.feature import Feature, FeatureSet
from arcgis.geometry import Polyline

input_polyline = Polyline({
	"paths": [[[-73.609551, 45.490678], [-73.584162, 45.513645]]],
	"spatialReference": {
		"wkid": 4326
	}
})

input_feature_set = FeatureSet(
	features=[Feature(geometry=input_polyline)])

pf = profile(input_line_features=input_feature_set,
			 dem_resolution='FINEST',
			 maximum_sample_distance_units='Meters')

print(pf)

 

Output:

I was able to retrieve the Z and M values using the following code:

input_polyline = Polyline({
	"paths": [[[-73.609551, 45.490678, 0, 0],
			   [-73.584162, 45.513645, 0, 0]]],
	"spatialReference": {
		"wkid": 4326
	}
})

input_feature_set = FeatureSet(
	features=[Feature(geometry=input_polyline)])

arcgis.env.return_z = True
arcgis.env.return_m = True

pf = profile(input_line_features=input_feature_set,
			 dem_resolution='FINEST')

print(pf)

 

Two steps were required:

1) The following lines had to be added, which set the environment variables for arcgis:

import arcgis
arcgis.env.return_z = True
arcgis.env.return_m = True

 

2) Z and M values must be provided within the input geometry for each point, and adding in zeros is sufficient.
