  • In this tutorial, I use the Freehand Raster Georeference plugin in QGIS to attach location information to an image. The output of this process is a PNG, but you can simply get at GeoTIFF if that is what you're looking for.

    A quick tip to not having to use the wonky tool is the "2P" Where you drag the right part of the image to the right part of the map and repeat it on the opposite side for best reults

    Since when this is called georeferencing? Where did you use ground coordinates? To do this why did you need to install the georeferencing tool?

    How did you get OSM basemap ? I've tried adding HCMGIS google map but it just crash, and I don't have your little globe icon.

    thank you, but how can i remove the black border then?

      I was stuck on this (QGIS newbie here), but if you follow the instructions from 3:40 and export the layer as a new shapefile, you should no longer have the black border.

    The wonky scaling tool makes this plugin rather useless in my opinion.

  • @SoftYoda
    @SoftYoda 5 месяцев назад

    Ok, your tool is REALLY BAD seriously why is the image stretching and there is no option to disable stretching ? Why does it always scale from the center (and not from two point i could pin) ? Worst tool ever created by mankind.

    • @SoftYoda
      @SoftYoda 5 месяцев назад

      Ok, my bad, the tool isn't bad, it's the tutorial just now showing it's full capabilities, there is a tool in the plugin that allow two point adjustment, thus making it a usable tool. I remove what I said previously. Just don't use the SC other than for quickly moving / scalling everything.

      Sorry again, it's not a good tool, it reduced the bit-depth of my tiff (from 16 to 8...)

      It's not my tool.

    • @SoftYoda

      @@derekcaelin No problem, it's not your fault, thanks for letting me know it exist. The tool is overall "usable" but the "additional options" dropdown menu while importing raster doesn't work, and the "export" often flatten my image into rgb value with less bit-depth. I don't exactly know why.
