topic get zonal statistics from points rather than a raster in Geoprocessing Questions https://community.esri.com/t5/geoprocessing-questions/get-zonal-statistics-from-points-rather-than-a/m-p/582877#M19286 <HTML><HEAD></HEAD><BODY><SPAN>I have 3 cruise tracks with many parameters of ocean chemistry data.
