      Getting an Intel i-7 at 3 Ghz, with 64GB memory and 2TB SSD drive would tremendously reduce processing time.
      Two Windows machines like that in tandem, running WebODM (with its sidekick QGIS) in parallel, might be an alternative to Cloud processing, running Linux ont these machine might speed things up quite noticeably, if you are comfortable with CLI. Long live OSF 😍

    • @HansvanderKwast

      I think you can. But if you need real-world coordinates, you need to provide Ground Control Points. You can provide these with a file or by using the GCP tool.

    Hi Hans, this tutorial is great, thank you for the detailed explanation.
    I have tried to project the tiff (orthophoto) into Qgis, but it does not seem to project right, have you encountered this problem before?
    Thanks, Sam

    • @HansvanderKwast
      @HansvanderKwast  2 года назад +1

      When you load the orthophoto QGIS should recognise the projection. You can only get a good projected result if the images have GPS data in the exif data and if the orthorectification goes well. You can manually add GCPs in WebODM to improve the orthorectification.

    How do you crop your image/project and keep the specific area we want to work on?

    • @HansvanderKwast
      @HansvanderKwast  3 года назад +2

      It depends on the output data from WebODM how to clip to your study area. The raster data can easily be clipped in QGIS using a polygon for your study area. If you want to clip the LAZ file, you can use Cloud Compare (cloudcompare.org/), LAS Tools plugin (ruclips.net/video/9LUuMYzwjfI/видео.html) or Whiteboxtools plugin (ruclips.net/video/V6VJxZyyTEg/видео.html).

      Do you mean for the GCP's. You can add GCPs from RTK measurements in a text file to improve the georeferencing. Without GCPs it will take the coordinates from the EXIF metadata.

I can just say that WebODM is a great open source tool (not just free, but open source) that does the job. Maybe someone else here has more experience with both.
