Hi thank you for the great explanation, can you please explain more on how to create the custom surface that includes the embankment surface?
I keep checking to see if there's any new videos. Hope everything is good at the geospatial tips Home Office 🙂
Hi, what file formats can be opened on this software (potree) other than .las format?
Looks like the programmers changed the menus. These days they just don't seem to care if they invalidate tutorials. There's no selection tot "build dense cloud" anymore.
Again, great video. Super helpful. Do you happen to have a video on how to edit the coloring on a DTM itself? I would like to show more colors in my gradient
would this work with the air 3?
Guten Tag, da ich gesehen habe, dass Sie die schweizer Landeskoordinaten gebraucht haben, gehe ich davon aus, dass Sie auch aus der Schweiz sind? Ich hätte eine frage betreffend LV95 Geoid und dem Import von dxf…. Würde mich rieseig über eine kurzen Austausch freuen! Freundliche Grüsse
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 [email protected] if you like.

Hey I love your Videos😍. Is it necessary to buy Agisoft Professional to calculate the volumnia of an excavation?
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?
wow this video is very clear!!!! thank u! im a freshman who start intern at a survey company, my mentor ask me to learn this skill
Glad it was helpful!
Wow. Thank you! Btw, in order to make this as live website. We need to learn HTML, CSS and JS first?
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. 😊
Thank you so much. This made an incredible difference to my washed out photos!
Fantastic!
Hey whatsuppp! Great greaat video! Is there any way I could do this with just Metashape? Or is it necessary to have Metashape Pro?
Please upload basic to professional tutorial videos step to step
Very nice. Congrats my friend. Liked. All the best, from Brazil
85/75 overlapis too much. 60/30 was industry norm and works perfectly fine.
Is there a way to make such videos for a construction-site with chunks coverin the progress over time?
@geospatialtips thank you , your videos are helpful. Could u do a video about merging chunks on larger datasets of images, When to merge how to remove erroneous points in merging. i find it difficult to get right on linear mission running 20 km at a time with GCPs .thanks
@Geospatial Tips which software did you use to merge/combine the videos using different visualizations to the final result you showed at the end of the tutorial?
Great video! After putting GCP I must re run alignment or using optimazation is enough?
What version of Agisoft meta shape do you have?
Hi. This video was made with version 1.8. Currently I use 2.1 however.
Thank for your video
Mark, can you tell me if you use a desktop or laptop for most of your map processing? What you recommend. Your channel is the best I’ve come across and I’ve been through it all. Much appreciation to you and your work.
Hey TexasHunter Thanks for the kind comments. I use a desktop for the processing work, even though mine is pretty old now, it’s reliable in a way I don’t think laptops are if pushed hard over long periods. I think a good GPU with 8GB worth of memory and at least 64GB of RAM are where you want to be for most jobs. You can use lesser specs, but you may find processes start to fail. (More RAM would be great, 128GB and up) Your CPU will dictate the speed with which certain tasks run, but I can’t recall seeing smaller CPUs causing failures like small GPUs and low RAM would. Hope that helps a little.
@@geospatialtips that’s exactly the advice I was looking for. Thank you sir
Hello! When I calc the focal length in micron, I am not getting the initial calculated number in Metashape. For example: 12.29 mm length divided by .00335821 = 3,659.68. The initial calculated length in micron is 3713.29. Im not sure where the discrepancy lies.
Hey Dennis! Question: The 3713 value form Metashape, is that before or after aligning images? I expect it'll change a little after your first alignment step and this difference isn't outrageous. But, if this is the value that Metashape gives right after adding your data, then I am not sure what is happening as your maths is correct.
@@geospatialtips This is before I aligned the images. After aligning, the adjusted value is F= 3705.749. So, what I did was start a new project, upload images and then manually input F= 3713.29 as the initial. Not sure if this is correct but after aligning so far everything seems to be in an acceptable range. I just saw that you do one on one tutoring type sessions. Im interested in setting something up soon!
@@geospatialtips correction; the value I manually entered prior to aligning was the 3659.69.
@@geospatialtips Fumbling my words here trying to explain. Ill recap here quickly incase anyone else is having the same issue. After importing images I went into the Camera Calibration menu and noticed that it had a value already populated (3713.29). Then I calc'ed myself using the equation 12.29 (Mavic 3 Enterprise wide lens focal length) X pixel size .00335821 = 3,659.68. After attempting to align the images, I went back into the Camera Calibration menu and noticed that the value did not change to the correct length in micron (3,659.68). So I opened a new project and started over, this time after importing the images I went back to the menu and manually entered the calc'ed figure. Then I aligned the images and my adjusted value is F= 3705.74, and this is within the acceptable range! Im not sure why Metashape is giving the wrong calculation after adding the images.
I have chunks of 1500 x 9 . I try to align using point cloud and it says not enough ram. Total photos are about 14500. So is there any way to merge all dem, DTM, ortho mosaic and 3d model using agisoft? System specs : 64gb ddr4 3600mhz i7 14700k Rtx 3060 12 gb 1tb nvme 3.0
Hi - yes, there is a solution for your situation. You'll want to setup your computer as a local server/node. This video will explain what you need to do: kzread.info/dash/bejne/dI2Gq6Vmoc7Aeps.html Using this technique I have processed 35000 images using a PC with about the same specs as yours, without the need to use chunks. All the best!
amazing video. Thanks.
Thank you!
Maravilhas.
Thanks!
If you had framed which button you were pressing, zoomed in and slowed it down, we could have watched those parts better. Thanks anyway.
Hi. Thanks very much for the feedback and suggestions. I have tried to implement some of these already in later videos and I hope they are easier to follow than this one.
Im having trouble. My cameras do not have any coordinates tied to the photo. How is the process different. My elevation is way off.
Hi - check the Metashape Preferences/Advanced tab and make sure the box is ticked to allow Metashape to read that kind of data on import. If it still is not there, right click on one of your images in File Explorer, go to Properties and then Details. Scroll down the list and make sure the coordinates are saved in the raw image data. If none of that helps you, maybe send me one of your images and I will take a look. ([email protected])
Hi, Iwould like to know. If I can do the process of aligning the coordinate system before any process mentioned in the video. Can I work with the correct coordinate system from the beginning? Or do I need to do this process only after aligning the photos?
Yes, you can set it beforehand as well and use your desired system from the beginning. The process would be much the same.
Dear, congratulations on the video... I have a question and maybe you can help me: In the Ground Control Points section of the Metashape accuracy report, I have the following Error X (cm) 2.33 Y error (cm) 2.07 Z error (cm) 1.15 XY (cm) 3.12 Total (cm) 3.33 My orthomosaic has a pixel measuring 1.72 cm and the DEM pixel measuring 3.44 cm If I measure the length of an object in orthomosaic, my error will be between (1x GSD) and (1.5 x GSD), right? In this calculation, should I consider the pixel of 1.72 cm in the orthomosaic or 3.12 cm in XY of the report? Is XY error only for area measurement? If I measure the height of the object, I should calculate the error between 2 to 3xGSD, right? Should I consider the 3.44 cm pixel in the DEM or 1.15 cm in Z indicated in the report? Thanks.
Thank you so much. May God bless you and your family.
hi. i have pics from my camera. but no coordiantes appear in the refrence column when i add them for lign. why they not appear?

Your tutorial is the best! Thank you!
hi i need an accurate Ortho mosaic of all data for cad work so is it necessory to follow gcp method or i can make without gcp also an accurate orthomosaic image as you know we can align in autocad easily without gcp ortho
Hi - it will depend on how accurate you need the end result to be. Also, is the drone you are using RTK enabled, or are you using just the onboard GPS? If only the onboard GPS it will be less accurate. Using this ortho is still possible, but you have no way of ensuring accuracy, so we get back to the question of, "How accurate do you need it to be?"
Thanks for the video! I am investigating different viewers and this looks promising. However, I had to install "electron" for it to run. I see in the original dev it says you can just "host on a site" which make me think it should not have any dependancies? Anyways, did you all have to install electron to get it to work? my potree.bat file says start ./node_modules/electron/dist/electron.exe ./main
Hi - I have used the viewer many times, on different workstations, and the need to install electron is based on the workstation and what had been previously installed. So yes, sometimes I have had to install electron but this is not usually the case. For the online viewer you won't need electron and can post the package directly to the web server and it usually works quite easily.
@@geospatialtips thanks for the reply. Glad to know that was not an unusual scenario.
Nice tutorial
teşekkür ederim
Audio geek here.. Consider dropping a "Compression" effect onto your audio track to bring up the lows and dump the highs.. Other than that - thank you.
Hi - thank you very much for the advice. We're all learning something new and I appreciate the help!
Thanks for the video. How come the model that is viewed directly on the software looks nicer and sharper compared to the .fbx export which looks less sharp? Thanks in advance
one idea; could be nice to see your cursor when youre working:D! thnx for the dedicated video
Hi, thanks for watching. Yes, that's a good idea and I have tried it in the more recent videos and will keep doing so!
Thx for your video. I would like to use this for landscaping on medium size properties. Which would be the most economic drone you would recomend for this?
Amazing tutorial, thank you!
Awesome video. How can I adjust it to show for example; RGB colors,but by clicking another button,to switch to deviations colors. Or any other attribute of point cloud?
OS Terrain 50 contour maps are not showing ELEVATION value when showing Categorized. Any help?
How can i use dji rc controller with this?
Like the video, just wondering what pc you are running to be able to do this. Thanks
Hi - it's an old but stable build. i7 8700k, 64GB RAM, RTX 3080 GPU
There are some options for implenet this is code?
Thank you for sharing how to. I was using Darktable but this seems simpler to batch and just as good results!
Wi ll subcribe but volume cranked & barely hear ya.
Thanks for watching and I hope you'll find the audio improved in later videos.
