    Love your tutorials! Im using 1m DEM and the end result is blurry and not at all like your result. Im also working at a scale of 1:70000 which maybe can explain the blurryness, but it feels like this work best on a coarser DEM. Will try it tomorrow. The result when not having the blurry slopes turned on is delicious however!

    Would you scale down the raster blurs if you had higher resolution data? We typically collect bathymetry at 0.5m resolution. So a blur of 5 and 10 maybe?

    • @JohnNelsonMaps
      @JohnNelsonMaps  6 місяців тому +1

      i blur to taste. whatever looks best is the way to go. i don't have a useful formula for it anyway.

    Wonderful video John! I am wondering why you used the Traditional hillshade technique in this video over the multidirectional one?

    • @JohnNelsonMaps
      @JohnNelsonMaps  2 роки тому

      the multidirectional one would get a little redundant with the slope layers. but i'm sure it would look good too, there's no wrong way to do this.

  • @monocilindro3655

      in that case I would give the original DEM, at the bottom, a dark-to-light blue gradient. should look great!

    Hi, This really impressive and a neat exercise to do over the long weekend. What is the accuracy of the DEM. Can it be done with a 1m or 2m DEM?

    • @JohnNelsonMaps
      @JohnNelsonMaps  2 роки тому

      this is a NASA SRTM image, which is 30m. but the concept should work for any DEM, whatever the scale.

    Hi Nelson! I've just tried this amazing trick but bumped into a small problem. When exporting the map, the hillshade altogether won't appear in the .PDF/.PNG. All I got in the map are the basemap (imagery) and the shapefiles. Do you have any clue or any tips for this type of problem? I've tried to restart the ArcGIS Pro but there are exclamation marks(click to repair) on those hillshades - may be due to the hillshades are considered as temporary files, if I'm not mistaken. Thank you in advance.

    Thank you so much john for this magic. I have tested it in a very steep mountain zone and its become very dark. I am using Alos Palsar DEM (12.5 m) and I wonder if I have to change the blur number of cells. Is there any rule of thumb between DEM spatial resolution and number of blur cells?. Thanks a lot!

    • @JohnNelsonMaps
      @JohnNelsonMaps  7 місяців тому

      Yes probably. But it also depends on the scale of your resulting map. I recommend experimenting and going with what looks best

  • @SoItGoes1985
    @SoItGoes1985 2 роки тому +1

    Do you have any advice for the number of cells (rows & columns) to blur given the original resolution of your DEM? For instance, would I need to increase the blur for the #10 and #20 stats surfaces using a 20 ft. DEM representing a county. Thank you, sir.

    • @JohnNelsonMaps
      @JohnNelsonMaps  2 роки тому +1

      i was using a 30m resolution DEM from SRTM. You can use whatever blur distance looks good to you. it also depends on what scale you want to view the map at. but overall it should be to your own taste and opinion. there's no right answer.

    It's really dope what you do with ArcGis Pro. I have a question. Is it possible to "merge" two raster data ? I want to create a raster with bathymetric data with topographic data. Thanks a lot for your awesome work!! Greetings from Chile :)

    • @JohnNelsonMaps
      @JohnNelsonMaps  Рік тому +1

      Thanks! Yes, but as is typical in GIS there are different ways of going about it. I would look into doing a “band math” raster function to add the two together. I think that should work.

  • @PBandHoneySammich

    • @JohnNelsonMaps
      @JohnNelsonMaps  2 роки тому +1

      for hillshades you can make the area more dramatic by changing the grayscale gradient in the symbology panel from one of the linear options (none or min-max) to a statistical one, like percent clip or standard deviation.

      it did. but the good news is you can use blend modes AND within-gradient transparency, so you have all the control as before plus some options.
