okay, I'm sorry, my screen, I just kind of lost the whole roster here. So someone's gonna have to quarterback these questions, what kind of drones we use a wide variety, some, a lot of the brand specific ones we use right now are DJI. We try and stay brand and equipment equipment agnostic. So if there are what what we're finding is there are specific tools, obviously, for specific jobs in different brands have kind of an edge over others for that. So as far as the drones go, DJI is our primary equipment vendor for that right now. Any other questions on that? All right. So aside from just tracking construction related things, aerial topographic mapping is another really amazing use and application for for this type of data collection. So what that means is not only can we map the ground, but we can get accurate ground contours. And being on top of that, still being able to merge our CAD models in with the environments. So another quick example of that would be like this, this is hundreds of acres that were flown all stitched together. And not only does this give you a accurate idea of what the the ground surface looks like, I apologize, it's loading slow. There's literally 10s of millions of data points in here. That's actually something I kind of glanced over the beginning, a point cloud what a point cloud is. And what that means is essentially, the drones are going out. And as I mentioned, they're taking hundreds, sometimes 1000s of high resolution photos. And part of the data processing there is it is taking all of these photos, and it generates a point cloud, which is literally millions of think of just dots or pixels. And those pixels are being overlaid with the high resolution photos. And so in this case, that's why this is a little grainy is there's there's millions of pixels that are trying to load here. Well, one of the other really cool uses is not only being able to have this as a 3d model, but using this I like to call this kind of a glossary of our of our called our model book here. And what I mean by that is you're able to use this model to navigate around to find all of the very high resolution photos that were ultimately Take into the generators model. So one of the things that this really helps out with is doing site inspections or trying to capture existing site conditions. This really ensures that no angle ever was missed at for anyone that's ever had to go out and do sidewalks or try and do fail field data collections. You're always worrying about missing a photo or doing whatever you can to capture the basically paint the best picture possible for the person or people that are not able to get out in the field. And so by generating these models, and also having all of the high resolution photos embedded inside of them, it really gives the best spatial awareness to anyone that wouldn't be able to go out in the field. So another one of many applications. This is really helpful as well, with GIS planning, or locating underground utilities, what we're also able to do is because these drones are GPS enabled, we're able to fly over the surface and act again, this kind of goes back to the previous slide of overlaying CAD drawings and stuff on there. But for example, underground utilities, we'd be able to fly over a neighborhood, for example, for laying fiber or something like that, generate a model like this, and then overlay the fiber designs on top of that, and have that geospatially accurate to the sidewalk or wherever those utilities go. So again, adds a whole new layer of being able to visualize and track where not only how construction was done, but where these things are existing for future planning, quality control, you know, all those things. Okay, so virtual walkthroughs. This isn't, admittedly a great photo of this. But essentially what these are, I think most people here have probably seen virtual, like home tours, on Zillow, things like that. That's essentially what this is, but we are taking it to another level. So there are a couple of different programs out there that offer this Matterport is one of them, which is what we use for this. And essentially how this kind of takes it above just a virtual walkthrough is these 3d walkthroughs are also geospatially. Data intelligent meaning as you're walking through these photos, or through a walkthrough, for example, in this compound, you're able to capture real time accurate measurements, you can also annotate and do some 3d mock ups inside of that virtual space. So again, not only giving us a visual tool, but it actually serves for engineering and design applications as well. So there's lots of really cool and useful applications for that again, at for nothing else, giving someone that hasn't been in there, a full immersive view of that walkthrough and ensuring that really no angle was missed through throughout walking that site. Okay, getting into Lidar and topographic, more topographic mapping. So there are many, many uses for LIDAR. Essentially, what Lidar is it is sending laser beams for all intensive purposes from the camera, and it is bouncing them off surfaces and timing, how long that light takes to get to the surface and comes back to the sensor. And what that does is it generates highly accurate topographic contour maps. This one was actually kind of a cool application that I decided to use for this presentation. This is a landfill that a large solar array was built on top of. And the intent of this mission was, as part of the ongoing maintenance and operations of the solar array. The client needs to track soil compaction to make sure that the array isn't shifting or sinking too far down into the old landfill. So these models, we go year after year and fly the exact same pattern and overlay that data on top of each other, which is what this table is showing here. And from that we're able to analyze the soil deformation and any other kinds of shifting that may occur here. What we found out is this array is vertically syncing by about an inch and a half over a two year span that's within design specs, but there's really no other way that you'd be able to go out and and identify that without the use of Lidar and some of these new technology applications. Some other great uses for it is LIDAR penetrates vegetation. So we're all aware of the Maui fires that just happened. One of the uses for this would be flying like those poll lines to identify where vegetation was overgrowing coming in contact with power lines, things like that, to be able to identify where vegetation mitigation needs to happen, as well as just ongoing maintenance for things like that.
