arcpy.sa.spline returns different results between ArcGIS Runtime for WPF and ArcGIS Maps SDK for .NET

Question

Hi,

we are migrating to ArcGIS Maps SDK for .NET, this includes a GeoProcessing Packages with an underlying python script that uses a call to arcpy.sa.Spline.

We noticed a difference in results on the edges of the result of the spline method.

We use arcpy.sa.spline with a mask applied through arcpy.env.mask and use the following options:

arcpy.sa.Spline(input_points, "SPOT", "#", "TENSION") Have there any changes been made to the spline method and how it works? or how the mask is applied? and if so, where could i find release notes related to this? There are quite a lot of versions between ArcGIS Runtime for WPF (10.2.5) / ArcMap (10.2.2) and ArcGIS Maps SDK for .NET (200.1) / ArcGIS Pro (v3.0.2). So it is hard to find any documentation on this. Thanks for your help!

Even though you are mixing languages, it's still exclusive to the language's documentation so you should be able to find mask or Spline information in the arcpy docs. Why it's producing different results could be due to rounding or available memory maybe and probably is worth reaching out to esri support for the issue.
