Help, beginnner coming from Drone Deploy. Will have a few questions :-)

Hi Guys,
I have been very successful using Drone Deploy for over a year, with a P4PV2 in a bigger company that could afford it.
Now I’m out on my own and cant afford DD for the amount of mapping I do. I am using lightning for now, and really liking it, but have a few questions. Things I know I can do in DD but unsure how to achieve in WODML.

  1. I ran a task and it completed and I viewed the results. They looked OK, but I wanted to change some settings to see if I could get better results, or to see what effect they have.
    So I go to edit the task, and change the options I want, and hit save.
    I am guessing I then need to re-run the task, but WODML starts right from the beginning again, including sending all the photos? DD would keep the photos for a period of time, and you could “re-process” them without resending which was much quicker?
    Am I missing something here?

  2. I sometimes would like to change the filesize of the Orthophoto, to be smaller filesize etc. in DD there was a nice menu option and you just selected the image size based on cm/px or filesize and it took a while and just spat out a new .tiff file.
    Is there some way to do this with WODML? or is it a full re-process including sending images again?

Thanks guys. There will be more questions! Please bear with me as I get up to speed!

  1. We purposefully do not keep your input images once the Task begins processing, nor do we retain final results longer than 14 days after processing ends.

  2. Using the WebODM desktop software, or WebODM Lightning Manager, you can modify and export 2D map products from the View Map function of a completed Task. However, we do not have the ability to change the GSD of the products for output at present.

This is an interesting Feature Request. Could you please explain a bit more why you would need this and how you use it?

If you’d like to, please file an Issue on our GitHub for this Feature Request:

It’s simple and quick to do in software such as GIMP, you can scale the image down to the size of your choice.

Thanks Gordon.
I was wondering if resizing a GeoTiff in this way would screw up the Geo-Referencing though?
I need the image to import to the correct location in AutoCAD after resizing.

“Save Geotiff data” is an option when saving a scaled image, so georeferencing should be preserved.

If you use Paint.NET on Windows, it also respects GeoTIFF metadata.
