Indeed, you would have to process your drones photos to an orthophoto and digital elevation model. This can be done in the Terrain Creator app which is included with in the package. Start the trial here: www.virtual-surveyor.com/download . This video kzbin.info/www/bejne/eWXMqqp5rteWqrs show the drone photogrammetry process.

We support coordinate systems that are in the EPSG database. If you can't find your vertical datum, then you can always process at ellipsoidal elevation. Afterwards, you can offset the DSM with Offset Z in Virtual Surveyor: support.virtual-surveyor.com/en/support/solutions/articles/1000292287-adjust-the-elevation-terrain-to-your-geoidal-or-local-height

Terrain Creator app + Virtual Surveyor app both come with any of the Ridge or Peak subscriptions. I have run it on an AMD Ryzen. Give it a go and let us know. You can download the trial version from here: www.virtual-surveyor.com/download

I produced maps of areas of different sizes using Intel i9 and Xeon, AMD Ryzen Threadripper. There are variations in duration, but it will produce results even on a computer with mid-range hardware.@@VirtualSurveyor

Currently, you will need to process project to a world coordinate system.

The latest version will install both apps, the Terrain Creator and Virtual Surveyor desktop app. There will be 2 shortcuts on your desktop or you can search for Terrain Creator in your taskbar Search. And a nice trick: if you drap and drop your drone photos in Virtual Surveyor, then a Terrain Creator project will be created and openend automatically!

The drone photos shown in the video are RTK. Here is the difference. When your camera positions are GPS quality (4-6 meters), the initial model will be less good and you might have to zoom in / search a little more to mark the ground points. But after a cycle or two, the model will be as good and your cursor would be spot on for the remainder of the sequence (you might decide to start the processing at this point). When the camera position are RTK/PPK quality (2-5 cm), the initial model will be immediately good and you model will be max quality after 1 cycle of marking ground points. Obviously with GPS camera position you would need more ground points, equally spread over your site.

@@VirtualSurveyor I already commented but it's gone. We flew a project using RTK. SoCal zone 6, NAVD 88, localized on an MWD baseline done with static observations. My data is feet off on the control points. Went back to check targets, perfect! Model did not improve as we located targets like in the video. Can you help figure this out? Surface model is of course terrible too!

@@tomthomsen990 A possible explanation. Did you use the same base station for the drone and the ground points? If you measure the ground points with a local base station and use OPUS for your drone /camera positions than it will not work. Use Opus for both, or use the local station for both. Let us know!

@@VirtualSurveyor We used our ground based base station for locating targets and for the drone flights. We ended up using Caarlson PhotoCapture and got as mush as 0.5' verticle errors compared to the ground shots even though the report showed the control to be very tight. Briton has since let me know that the Terrain program has been updated and I'm trying it now 8-6-24. See you in Vegas next month!

Yes, it is. Simple upgrade to the latest version. The latest Virtual Surveyor installer includes both the Virtual Surveyor and Terrain desktop app. 1 subscription, 1 installer, 2 apps. The application will aks to update itself. If not, go to your portal: my.virtual-surveyor.com/download.

@@VirtualSurveyor which subscription levels is it included with? Or is it everyting except Valley?

@@jeremywebb2806 The Terrain Creator desktop app comes with a Ridge or Peak subscription. You can compare all feature between the different plans here: www.virtual-surveyor.com/all-features

Yes. Off Course. Here is a Dropbox Transfer link to the photos and ground control poins that were used in the video: www.dropbox.com/t/yxGpMjhP7rHZFa8y

Thank you! 😊

Hello ... This issue is caused by a bug with AMD graphics drivers. We have workaround for that. Can you submit your question in our support system? One of our product specialists will help you out. support.virtual-surveyor.com/en/support/tickets/new

Go to www.virtual-surveyor.com and click on any of Start a trial buttons

You can load orthophotos, digital surface models, point clouds, gis, cad, ... into Virtual Surveyor. Have a look here for the supported file formats: support.virtual-surveyor.com/en/support/solutions/articles/1000273543-supported-input-file-formats

Hope you enjoy it!

Any mapping drone will do: DJI branded or non DJI branded. A mapping drone allows you to fly a programmed pattern over your project area so that the photos overlap. You need this to produce the orthophoto and digital elevation model (DSM) which go in Virtual Surveyor for the calculations.

@Virtual Surveyor is RTK needed to get this data? Thank you for your response, btw. Hope you get more subscribers and viewers.

@@konp368 You need accuracy to get good measurements. You can achieve that with or without RTK. Without RTK you would typically need a number of ground control points, with RTK you theoretically don't need ground control points but using at least 1 is a good practice.

These are measured parameters. There exist tables of densities online. Here is an example: www.engineeringtoolbox.com/density-materials-d_1652.html

Try to export form DJI in a project coordinated system and try again to load it in Virtual Surveyor....

@@VirtualSurveyor Yes, thanks ! It was the coordinate system at the time of exporting from Terra. Thanks !

While Virtual Surveyor is focused on survey drawings, it does not support photogrammetry. Not the strongest photogrammetry on the market but it is offered.

You can drag and drop your LiDAR data (.las or .laz) in Virtual Surveyor (create a new project first). Virtual Surveyor will convert your LiDAR data to a terrain automatically. When that is doen you are ready to create stockpile inventory. Let us know if you can get it to work. If not we can help you through an online demo.

Hello John, our pricing is available online on www.virtual-surveyor.com/pricing

The accuracy is determined in your photogrammetry process (production of the elevation model). That accuracy is determined by how you fly (the higher you fly = the lower the accuracy but it will require more work when you fly low so there is a trade off). Also the ground control points you use will influence the precision. Virtual Surveyor calculates all its output based on the information you will put in...

Our customers make that decision. They use Metashape, SimActive, ... in order to produce an orthophoto and elevation model that they can read in Virtual Surveyor. There are many more...

Este trabajo se realizó con la versión Peak (puntos de paso bajo). También puedes hacerlo con Ridge pero te llevará un poco más de tiempo.

Yes Jeremy. Just export the .las from DJI Terra and drag-and-drop it into your (empty) Virtual Surveyor project ...

Virtual Surveyor applies a different concept. We don't filter the data but give you tools that allows you to model your topographic surface under your vegetation. That solves 2 challenges: 1) you model the ground level + 2) you get your data in a CAD compatable format. This video shows that process really well: kzbin.info/www/bejne/eZ23paCNe5lorLs

Our pricing is available online and completely transparent. Have a look here: www.virtual-surveyor.com/pricing You can take a subscription as short as a single month. Auto Renew is off by default so no surprises at the end of your month. You can always revert to the free Valley plan once your paying subscription ends. Make sure to start a free trial on our website.

@@VirtualSurveyor thanks

Hello Phong ... We have a free Valley version which allows you to create and export a lightweight CAD model from your drone data. Make sure to look at that option as well. I don't think that is overbudget ;-)
