The correction of the y coordinates on the table is coming soon. Regarding rasters with a high number of minimum (or maximum) values, automatically blocking at a minimum number of samples makes it impossibility of using those points for other analyses of the territory. In fact, the scanning and search for points occurs progressively following the columns and rows of the raster and not morphometric elements. I had however thought of a monitoring system that warns the user when the max and min points have been found in order to block the process and obtain a level with the partial mx/min
