I don't believe there is a render option, like you are describing, at least not one that I know of. But I am interested in the issues you are having with the mosaic. Maybe it is just how I am reading your message, so please correct me if I am wrong. The mosaic doesn't have to be like a puzzle (accurate alignment and blending) and could easily be created as a whole/single scene that is exported as a single file, rather than a tiled export. Let me know if I can help a little more?

After the point cloud process. The points collected in the tie-point process will be used to optimize your camera alignment. Thus, if you clean up too many points, you run the risk of having images that are no longer aligned. Also, cleaning the tie points will not affect the region for which the dense cloud is created, as that is determined by the aligned images and the region box. *You would still want to run the gradual selection steps to optimize your tie points though.

Hi - If you have images captured at various altitudes and/or you have oblique images along with those captured at nadir, then I would use the "Adaptive Model" option when optimizing the camera. However, if you have a more simple dataset where images are captured at a single altitude and generally all at nadir, then you do not use adaptive modelling and you would have the boxes checked per the default setting. I hope that helps.

@@geospatialtips It helps a lot! Thanks for the replies 👍

Thanks! Glad to be back and hopefully consistently so from now on :)

Hi - Thanks for the feedback. This video is pretty old now and I think I've got the cursor visible in all videos that follow this one. Time for a redo of the Metshape walkthrough anyway I think! Cheers

@geospatialtips is there any other app you can recommend for photogrammetry that is not complicated and free

Thanks! If you have a suitable dataset I could use, please send it along and I will make the video for you :) geospatialtips@gmail.com

Yes you can. In Metashape, just set the drive letter as the location, like "D:\" and in the node batch file you would put "--root /" -> both without the quotes.

Sure, send me some data and I'll take a look at what we can do with it! geospatialtips@gmail.com

I knew there had to be a simpler way! Thank you :)

You're welcome!

Hi Paul - no, I can't say that I have. But it sounds like something worth a try. So long as the corrections are some kind of average across all of the images, then great. I would be concerned if it is adjusting each image based on it's own data, but if you are getting consistent exposure etc. across all the images, excellent.

@geospatialtips I've tried it after asking this and it turns out pretty good.

You're very welcome! :)

Sounds like it's time for a video update. Thanks for the feedback!

Hi Hans, thanks for the comment. This exclusion was done intentionally. I find that the majority of viewers do not have or do not use RTK enabled drones and thus this was to clearly illustrate what Metashape does with control points if left unchecked and unmanaged. You are of course correct that when we use RTK (more specifically PP-RTK) positions, these should be taken into consideration and used to guide the orientation. RTK is only accurate in a relative sense unless setup on a known points and observed for extended time periods, hence the need to use the "Update" function as you have pointed out. If it was possible, I'd only ever use PP-RTK and then even the "Update" function should become unnecessary. Keep in mind too that ALL positions are only as good as the equipment being used and blind faith in any one of the technologies being used is a risk. If you and the team at RedCatch would like to supply some data and we can make a video together to show the best way to harness RTK, specifically with RedCatch, please do get in touch! Thanks

Welcome!

You could Photoshop it all, but that's a bit of a pain to do. Realistically, with a project of the size you have mentioned, I would create the mosaic in a specialized software, such as OrthoVista. (Bingo would do much the same) In OV you can set it to balance data per flight and across multiple days, edit the radiometry of the images individually, within a region or per flight and so on. Then, create the mosaic which would thus be much better from the start. Any remaining edits for colour, seamlines, balancing etc. can be reviewed and edited and then the mosaic, or just the are you need, can be redone.

@@geospatialtips thanks or the reply. Never heard those software, but ill look it up. Currently im using photoshop to edit the tiled mosaic. The fact that PS cant save georeference information was solved by exporting the tiled mosaic together with the World file (.jgw). Ive never found geospatial software that can edit raster data just like PS did. So the method above can be a workaround

@@mikealpha4462 Yes, the loss of referencing is a pain, but as you say, it can be overcome. OrthoVista is pretty expensive, owned and distributed by Trimble these days, but it certainly gets the job done. You would export rectified images from Metashape (or whichever program you use) import and edit, then create the mosaic in OV.

Hi, I can think of a few possible reasons: 1. If you are using a textured model, confirm your model looks great before the video and that it isn't just a low quality texture issue. (I assume this you have already done) 2. Maximize the screen space before creating the video. If you screen size is small and then you try 'blow it up' to full screen to view the video, the scaling will add the blurred effect. 3. Change your framerate and resolution that you are using to record the video and see if it makes any difference? 4. If all else fails, feel free to send me some screenshots or a screen recording via email and I'll take a look for you. geospatialtips@gmail.com

Hi Dennis - you are correct. In this case the best fit makes the most sense (unless you had a custom base from before the pile was there). The mean plane would mean you lose a bit of material and the volume you get would be off. I'm not sure if you have watched this video, but I explain the differences between each plane type in a little more depth, maybe it'll help you. ua-cam.com/video/9t-EJBVqgLE/v-deo.html

Hi - I'm not 100% sure, but this link makes it look like you can, with some adjustment. Maybe worth taking a look. support.dronesmadeeasy.com/hc/en-us/community/posts/15327269268884-Mavic-3T-Thermal

Hi - go to 'Model' then 'Show/Hide Items' and then you should be able to hide these elements there. If you are still have trouble please send some screenshots to geospatialtips@gmail.com and I'll take a look for you.

Hi - it has been renamed "Build Point Cloud" and is a little further down the list than it used to be. It performs the same function however.

@@geospatialtips i had the same problem as @josephagouze3770. I was able to generate the dense point cloud following your instructions, but now the "filter by confidence" is and remains greyed out. Any idea what to do?

Hi - yes, when you create the point cloud, select the Advanced option and there will be a check box you need to enable that allows you to calculate the point confidence. I suspect this was turned off for you.

@@geospatialtips thank you very much

I'm having the exact same problem. No more Dense Point Cloud in v 2.1.2

Hi - it's just called "Build Point Cloud" now, but it does the same job.

Awesome, thank you!

Glad you think so!

Working on it!

also global mapper is not free

I never suggested Global Mapper was free. For Map Pilot Pro I was just pointing out that the free version is decent for folks new to the photogram world.

Yes, unfortunately this is the case. However, it seems that it's due to a DJI restriction, rather than a processing software limitation. Maybe one day they'll open it up...

Glad you liked it

Hi! Sorry I've been pretty quiet this year. It's been a bit of a challenging year so far, but things are looking up and I plan to add to the channel soon and hope it's of some value to you all! Thanks for checking in :)

@@geospatialtips Sorry to hear about the challenges and I hope everybody is okay. Glad to hear that things are looking up!

This is the complete list per the software documents: cloud.js: A JSON file that contains metadata like spacing and bounding box sources.json: A file that contains build information .hrc: An index file .bin: A point cloud data file .las: A LAS data file .laz: A LAZ data file

Yip, they did change it up. It is now called Build Point Cloud (or something like that) a little further down the same menu. But, it does the exact same thing.

@@geospatialtips Thanks! That's very useful. I don't know if the recent trends in software to just change menu items at will, voiding UA-cam tutorials out there, is good or bad. I sure would have loved to ignore users back when I was stuck writing software that had user interfaces. But it still seems irresponsible to me! I suppose, with AI rising, it won't matter much.

Hi - no, I'm not Swiss, I am South African. I just happened to use a Swiss dataset for this video. I'm happy to help you if I can, you can email me at geospatialtips@gmail.com if you like.

And another question: is it possible to use the demo version of Abisoft Metashape Professional?

Hi - yes, you can definitely use the demo version to calculate volumes and do all other things.

Hi - thanks so much! Yes, you'll need t have the Pro version for volume calcs.

Thank you. But why does not everyone do it with the demo version which is free?

@@retobrugger3270 A few reasons I can think of: The demo is only free for 30 days, after that it won't work. Secondly, I believe the terms and conditions state that the demo cannot be used for any commercial work or financial gain, so technically it shouldn't be used for such things. Nothing physically stops you from doing so and continuing to use it, but those are some reasons, nonetheless.

Glad it was helpful!

Hi! No, you don't need to know any of that. The software will create the files you need and you would need to upload them to a server. At worst you may need to edit a couple lines in the HTML file, to make sure you are pointing to the data, but that's all.

​@@geospatialtipsThank you for the tips. 😊

Fantastic!

Hi - unfortunately only in Metashape Pro
