I've currently doing some work on interpolation and have found that spline methods are available in both Spatial Analyst (<A href="https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/how-spline-works.htm" target="_self">here</A>) and Geostatistical Analyst (<A href="https://pro.arcgis.com/en/pro-app/latest/help/analysis/geostatistical-analyst/how-radial-basis-functions-work.htm" target="_self">here</A>). So I have a question: are the Regularized and Tension splines available in both identical to each other? I can't find any documentation that suggests otherwise and haven't had a chance to test this.</P><P>I find this confusing but also not surprising given that the&nbsp;<A href="https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/how-trend-works.htm" target="_self">Trend tool</A> (Spatial Analyst) and <A href="https://pro.arcgis.com/en/pro-app/latest/help/analysis/geostatistical-analyst/how-global-polynomial-interpolation-works.htm" target="_self">global polynomial</A> (Geostatistical Analyst) are so redundant that the documentation is literally identical just with the name switched out!</P> Wed, 14 Jul 2021 02:58:32 GMT https://community.esri.com/t5/arcgis-pro-questions/splines-in-spatial-analyst-vs-geostatistical/m-p/1078564#M43276 panta_ray 2021-07-14T02:58:32Z https://community.esri.com/t5/arcgis-pro-questions/splines-in-spatial-analyst-vs-geostatistical/m-p/1091060#M44723 <P>subtract the results of spline interpolation from both toolsets.&nbsp; If they are identical, you will have a 0 raster.</P><P>as for your second question, terminology and application differs in disciplines so nothing is redundant</P> Sat, 21 Aug 2021 22:42:41 GMT https://community.esri.com/t5/arcgis-pro-questions/splines-in-spatial-analyst-vs-geostatistical/m-p/1091060#M44723 DanPatterson 2021-08-21T22:42:41Z
