https://community.esri.com/t5/arcgis-pro-questions/how-to-create-weighted-sample-points/m-p/1167670#M54409 <P>I have a classified satellite image and I want to create a confusion matrix to check its accuracy. The satellite image has homogenous areas (1 landclass label) and complex regions (lots of landclass labels within a region) For the sample points, I want them to be weighted so they're more likely to occur in complex areas where lots of labels occur.&nbsp;<BR /><BR />My current plan is to do an edge detection to act as a measure of complexity (areas with more classes should have more edges) and use that to weigh the random sample point, where by an area with a high number of edges is more likely to have a sample point.<BR /><BR />How can I do this?</P> Mon, 25 Apr 2022 19:00:59 GMT GISCoffee 2022-04-25T19:00:59Z https://community.esri.com/t5/arcgis-pro-questions/how-to-create-weighted-sample-points/m-p/1167670#M54409 <P>I have a classified satellite image and I want to create a confusion matrix to check its accuracy.
