Multispectral Ortho Processing in Sitescan

Matt-Barrett — Fri, 22 Mar 2024 13:26:35 GMT

When will full orthophoto processing and production be available in Sitescan INCLUDING GROUND CONTROL POINT PROCESSING? That is the primary thing that I want to do in Sitescan that I can't currently do. I have a mavic Enterprise 3M with RTK capability. Every flight I collect RGB and MS images for ortho production, because why wouldn't I, if my drone can do it? But I can't process the multispectral images with GCP's. And the only reason I can process them at all is because of the RTK. Amazingly they come out pretty close because of that, but if I can add GCP's that will eliminate the approximately 1-foot shift that remains.

This drone captures 1 RGB image and 4 MS images for every shutter snap. The 4 MS images when composited comprise a 4-band MS image. It captures Green, Red, Red edge, and NIR. The image attached shows a park in the city I work for. That image is the end result of 2,544 raw images because I flew fairly low. But even though you can't see it as this scale, it has an image shift of maybe 1-foot.

I'm frustrated because I want one software solution that can process both, and if Sitescan can't do it, I'm going to have to switch to pix4d or something, because I can't justify multiple software solutions for drone image processing, however much I might want to. So while features like pavement condition evaluation is really cool, please know that the absolute number 1 thing missing in Sitescan in my opinion is GCP processing for MS tiff images. I just want to make CIR orthos!

Thank you for enduring my rant. I promise I'm actually a nice person.

Thank you for your feedback. This is exactly the feedback we appreciate. Please stand by while I dig a little deeper to see if we can find a way to make this work for you. Either way I will get back you shortly.

Thanks Tom! I think it's because they're tiff images. Sitescan can't display them, but it can process them. But because you need to view the images to identify gcp's, I can't do it.

Hi @Thomas_Sweet and @Matt-Barrett, just chiming in to say I'm in exactly the same boat here. Having GCP support for ms .TIFFs would be huge for me. I also can't justify paying for two photogrammetry software solutions.

Given that this was a year ago, was there any resolution to this issue since?
