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.

Hi Hans (or community) how do I SHARE? I see at 13:15 there's a SHARE button, but that is not popping up for me. Would love an easy way to share my data with a client. Thank you!
Hello. Thank you for sharing this great tutorial ! I have a question please that was not very clear. Can you use also photos without exif data (not geotagged) in this software ? Thx!
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 . Thank you for sharing this amazing information . Im new to WebODM . I wanna buy the software . And Im not sure if its going to work offline without internet ! Somtime I travel for long distances fo remote area . And I dont have any link . Is this software can works also by offline situations?
Hi. You can install it on a laptop and use it offline. Basically it runs a server locally. Instructions are here: ruclips.net/video/LT0dYCh8pXw/видео.html
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
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.
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).
You can optionally upload the GCP file when you upload the images to WebODM. You can also create GCPs with the WebODM interface, save the file and upload it prior to the processing.
@@LuisAlbanes You can digitize GCPs that are visible on an existing georeferenced GIS layer (can be any that is useful) and clearly visible on the images that you want to orthorectify in WebODM. Export them to the format for the GCP file. You can take the points from a high resolution satellite image or existing orthophoto for example.
Drag the tiff file from the file explorer to the QGIS map canvas. Or better: use the QGIS browser panel to browse to the file and drag it from there to the map canvas.
do you need to have a drone to do this or could you use normal camera images from the ground just as you can with a photogrammetry program like metashape
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.
Awesome. Also when I try to configure the settings in the 3D Map window my model just disappears. I try zooming to extent and this does not appear to have any effect.
According to this ODM tutorial (docs.opendronemap.org/tutorials/) it's 83% overlap and sidelap for flight lines for 3D, but you can reduce this to 68% for a crossgrid pattern.
I created this kind of map from Webodm (it was a free trial but now it's over). how to continue my project, do you know any opensource software for drone image processing.
@@HansvanderKwast thank you sir for your immediate response. i already use this software but I have no financially good to buy this software. do you know another opensource software to continue my works
@dilshanherath1356 That's what I mean. It's open source, free, no license cost. Check this video on how to install it: ruclips.net/video/LT0dYCh8pXw/видео.html
I've never used Agisoft Metashape. When I look for comparison websites I don't find any that compares features, only (paid) services. So I can't answer your question. 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.
I just dont see any videos on actually flying just the post processing part. Need to know what app to use to collect data to process on this application
super cool. thanks for taking the time to show this.
Muito bom seu vídeo. Sei 1% de inglês, mas com a ajuda dos slides deu para entender perfeitamente. Obrigado por compartilhar isso com todos!
Thanks for a great tutorial! I have been searching for a while on how to do this including the installation of webodm.
Thank you so much for your simple yet very informative video in a short time.
Hi! Thank you for uploading this video....very useful for me. Can you also do a video on how to install WebODM?
This video was excellent.
As always.
useful and easy to follow, thank you...
Dankjewel voor dit.
Excellent Tutorial
Very nice presentation.
Dear Hans, what is your opinion on the applicability of ODM generated DEMs for flood studies..compared to Lidar products?
Thanks for excellent video, what would be the processing time it will take
That depends on many factors: amount of images, resolution, computing power, settings of the algorithms.
@@HansvanderKwast Thank you 🙏

How do you crop your image/project and keep the specific area we want to work on?
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).
@@HansvanderKwast Hello Hans, are these plug ins for Weodm?
@@LuisAlbanes The plugins are for QGIS. You can use them after loading the WebODM results in QGIS.
@@HansvanderKwast Great thanks a lot! I have QGIS and I will try them ...
Hello Hans, is there a way to export the map we have made on WebODM?
Yes, ruclips.net/video/c38DUn7kKYk/видео.html
Thanks Hans and ... when do you need to make Ground Control Points?
You can optionally upload the GCP file when you upload the images to WebODM. You can also create GCPs with the WebODM interface, save the file and upload it prior to the processing.
@@HansvanderKwast Thank you, but the GCP shall be taken with a precise instrument right?
@@LuisAlbanes Depends on the accuracy that you need. You can also get them from a georeferenced GIS layer.
@@HansvanderKwast where can I find the georeferenced GIS layer ? forgive my ignorance
@@LuisAlbanes You can digitize GCPs that are visible on an existing georeferenced GIS layer (can be any that is useful) and clearly visible on the images that you want to orthorectify in WebODM. Export them to the format for the GCP file. You can take the points from a high resolution satellite image or existing orthophoto for example.
I downloaded QGIS and installed it. How do I get it to open or how do I use it to view the tiff file created?
Drag the tiff file from the file explorer to the QGIS map canvas. Or better: use the QGIS browser panel to browse to the file and drag it from there to the map canvas.
Can we use WebODM to process radiometric data (thermal drones for solar farm inspection)?
I read your comment, I also have the same issue, so did you find some solution for it, please tell me.
do you need to have a drone to do this or could you use normal camera images from the ground just as you can with a photogrammetry program like metashape
You can also use normal camera images or videos. See this nice demo by Klas Karlsson: ruclips.net/video/pe04m-gHM-M/видео.html
@@HansvanderKwast Thanks Hans - Klas is a favorite of mine I must have been asleep to miss all this. Covid brain.
Is it possible to use RTK data in WebODM?
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.
Do you know if new versions of QGIS have point cloud support is it only 3.18?
Point cloud support is for QGIS 3.18 and newer.
Awesome. Also when I try to configure the settings in the 3D Map window my model just disappears. I try zooming to extent and this does not appear to have any effect.
You mentioned an 83% overlap for 3D. Is that front, side or both?
According to this ODM tutorial (docs.opendronemap.org/tutorials/) it's 83% overlap and sidelap for flight lines for 3D, but you can reduce this to 68% for a crossgrid pattern.

@@d.jackson9836 just use drone deploy app. Just dont process.
If you are flying a DJI drone you can use DJI Ground Station Pro.
