Results of spatial filter depends on spatial reference

AnastasiaNaymushina

I have a question about applying spatial filter tool in Insights for ArcGIS.

We’ve noticed that the result of this tool in Insigts and in Arcgis Pro or ArcGIS Online differs. The source data of both layers is in decimal degrees - WGS84.

 

ArcGIS Pro returns 3860 intersecting features, Insights returns the same result only if data published as service in decimal degrees (WGS 84).

 

 

If service with the same data is published in Web Mercator Auxiliary Sphere – it returns 1581 feature.

 

 

What does it mean?

are the spatial filters the same?  

Is it intersect? within a distance of? within a distance of geodesic? within an extent?

The combination of the filter geometry and the filter method and the coordinate system can yield unexpected results.

If you have an extent defined in geographic coordinates, I would not simply project that extent (either physically or ont he fly) without using a geodesic densify first.

Perhaps so more details would help clarify, given my translation skills are limited.
