Hi,<br><br>OK - with ST_SummaryStats it is easy to retrieve the highest value in the raster, but then I only have this value. Now I want to retrieve (information about) the cell/pixel having this value, to be able to visualize the highest point on the map. My original query (see first post) does give me this information (after 45 seconds...).<br><br>How would I go about to get hold of the pixel with the highest value, knowing this value?<br><br>Cheers,<br><br>Egge-Jan<br><br>On Sunday, June 24, 2012 8:47:58 PM UTC+1, DavidRA wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;">Why don't you use ST_SummaryStats instead ST_Value?
