I a little bit stumped. I have the entire world as a raster with values ranging from 0-7. I am wanting to extract the highest values (ideally only those from 6-7) as points. Is there any simple way i can do this? Current i am manually putting points in the high areas that i can visually see and then using "Extract values from raster" to give the points a value.

This is tedious and also isn't 100% accurate and i also have to produce it on many rasters...

Here is an image so you can see what i mean (Just put in NZ for an example) Basically just wanting points in all the red areas (values 7-8) and then i can Extract values from Raster.

    Have you tried selecting the higher values and then just converting to points? – user2856 Sep 16 at 9:03

    I dont understand your question fully. What if there is a 6.8 next to a 6.9, then you only want a point at 6.9? Then I think you want to find local maximas. Or do you want points at every pixel if the value is >=6? – BERA Sep 16 at 10:38
  • @user2856 how do you select only the high values in a raster? – Vanessa Sep 17 at 0:03
  • @BERA Yes i am wanting all the points >=6. – Vanessa Sep 17 at 0:03

I just figured it out, thanks everyone. This is what i did Because my Raster is float i X it by 10000 to make it whole numbers. I then converted my Raster to an Interg I "Build Raster Attribute Table" I then selected the high values in my attribute table & did the Raster to Points

How about doing a "Reclassify" for the high-value-regions. Then convert it to singlepart polygons, convert them back to raster via FID and then use the tool "Zonal Statistics", then taking the Raster Calculator with something like Con(Max=Reclass, Max) and convert the resulting raster to point?

  • Hey, i tried this, but my values are decimal. I cant seem to put in a range in the New Values and i cannot write out every decimal value from 5 to 6. (i.e 5.1 = 5.1, 5.11 = 5.11 ...) Any ideas? I want to keep the high cells with their current values. I will post a picture – Vanessa Sep 16 at 23:54
  • I posted my picture up the top, i wasn't sure how to post it in the comment @Anna – Vanessa Sep 17 at 0:01
