"Have their center in" equivalent in ArcGIS API for Python

geo_sunriver — Tue, 09 Sep 2025 18:08:17 GMT

Is there an equivalent method in the Geometry class in the ArcGIS API for Python to the "Have their center in" operation that is used selecting by location in ArcGIS Pro?

Geometry.EWKT
Geometry.JSON
Geometry.WKB
Geometry.WKT
Geometry.angle_distance_to()
Geometry.area
Geometry.as_arcpy
Geometry.as_shapely
Geometry.boundary()
Geometry.buffer()
Geometry.centroid
Geometry.clip()
Geometry.contains()
Geometry.convex_hull()
Geometry.crosses()
Geometry.cut()
Geometry.densify()
Geometry.difference()
Geometry.disjoint()
Geometry.distance_to()
Geometry.envelope
Geometry.equals()
Geometry.extent
Geometry.first_point
Geometry.from_shapely()
Geometry.generalize()
Geometry.geoextent
Geometry.geometry_type
Geometry.get_area()
Geometry.get_length()
Geometry.get_part()
Geometry.has_m
Geometry.has_z
Geometry.hull_rectangle
Geometry.intersect()
Geometry.is_empty
Geometry.is_multipart
Geometry.is_valid()
Geometry.label_point
Geometry.last_point
Geometry.length
Geometry.length3D
Geometry.measure_on_line()
Geometry.overlaps()
Geometry.part_count
Geometry.point_count
Geometry.point_from_angle_and_distance()
Geometry.position_along_line()
Geometry.project_as()
Geometry.query_point_and_distance()
Geometry.rotate()
Geometry.scale()
Geometry.segment_along_line()
Geometry.skew()
Geometry.snap_to_line()
Geometry.spatial_reference
Geometry.symmetric_difference()
Geometry.touches()
Geometry.translate()
Geometry.true_centroid
Geometry.union()
Geometry.within()

Or do I need to to compute the centroid (or true centroid) of my polygons and then check those points with a spatial predicate like .within() or .contains() against the container polygon?

I'm trying to create a script in an AGOL Notebook that will query taxlots with their centers inside an unincorporated communities polygon.

it isn't in your extensive list, not online, so your plan of course would be to use

true_centroid (a true centroid if it is within or on the feature) since they also lack a labelPoint method

This would only be of concern if you have extremely concave polygons

Thanks Dan! I'll continue forward with your advice. I'll post my solution once I complete it...

The methods below worked great.

dc_taxlots_sdf["CENTROIDS"] = dc_taxlots_sdf["SHAPE"].apply(lambda g: g.true_centroid)
dc_taxlots_sdf["SUNRIVER_TAXLOTS"] = dc_taxlots_sdf["CENTROIDS"].apply(lambda x: x.within(sb_geom_3857))
