Hi
I have loaded a DEM dataset into a Postgis raster table. And a shapefile
with polygons for a number of regions into another table.
For a couple of days now I have been trying to extract the height and
location of the highest point in each of the regions. But I cannot find a
way to do it.
I am able to find the highest value in each region using ST_SummaryStats()
but not the location (coordinates) of that value.
Can anyone point me in the right direction how I should do this?
It must be possible to do this in Postgis right?
Thanks
Jesper
