Is there a technical limitation to adding more than four points? Or could this be a potential enhancement for the future?</P><P>Cheers,</P><P>Luke</P> Thu, 15 Feb 2024 16:23:23 GMT LukeCalladine 2024-02-15T16:23:23Z https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/controlpointsgeoreference-is-maximum-of-4-a/m-p/1382892#M83652 <P>Hey all,</P><P>I've been using the new MediaLayers to do some simple georeferencing proof of concepts.</P><P>Its a really powerful tool but I've found a slight limitations of four control points - where adding a 5th or 6th point would "tighten" the georeferencing in line with expected results.

I'd suggest georeferencing the images in Pro and publish them as a service if higher accuracy is needed.</P> Thu, 15 Feb 2024 21:10:30 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/controlpointsgeoreference-is-maximum-of-4-a/m-p/1383122#M83655 Sage_Wall 2024-02-15T21:10:30Z
