Drone2Map for Utility Inspections and Corridor Management

just east of LA there's an area known as the Cajon Pass that's an incredibly important geographic feature for a number of reasons one of the first ones is the fact that a number of very important transmission lines run through this this corridor and it's really a bottleneck there's also an interstate as well it's an important rail corridor that goes right through this region and in 2016 there was a huge wildfire that impacted this area and in the southern portion of the perimeter of the fire you can see there wasn't any burn that happened and the one thing that we were really curious about was how vegetation was gonna impact this transmission corridor in the years following since this area didn't burn how would this vegetation now impact the corridor in the years ahead so we decided to go out into the field and bring along a drone along with a partner of ours to be able to fly and see what the vegetation could look like in this in this corridor so during the flight we wanted to capture three different things and apply it using drone to map one was conduct a tower inspection two was build out some of the 2d products that drone map could produce on the fly and three build out some 3d visualizations of the towers and also see where the vegetation could start to encroach so now opening up drone a map in the field we can get started so what we did initially was run the data through and do an inspection so in the field using drone a map we were able to land the drone pull out the SD card and actually come in and look at this high detail imagery right in the field to see exactly where there might be issues on the insulators or other features and assets and as we went through our imagery we found a couple of interesting things so as i zoom into this photo you can see very quickly that there's a couple of Av nests up in the tower so this along with some of the other features of the inspection give us a great way to look at all this imagery right in the field the second thing and third thing we wanted to do was actually take drona map and bring all this imagery and data to the back office for processing to build out the 2d and 3d products so the first thing we were able to build out was an ortho mosaic so here you can see all of the flight lines and locations that photos were taken by the drone and as we zoom in we have the ortho or the base imagery that's provided by ESRI through ArcGIS online and let's turn on the ortho that was built out by drona map so here drona Maps stitches together all the photos and produces this beautiful ortho mosaic and gives a lot of detail of the vegetation and everything underlying this corridor as well it provides a lot of 3d outputs and this is really the third thing we're looking to do so as I turned your own a map into a 3d view I can zoom into this area and turn on a couple of the other products that have put out the one was a digital terrain model which gives me an idea of the base elevation as well as a digital surface model so what is happening with the canopy and all of these are being built out by a point cloud that's generated as drona map looks at all of the imagery and interprets the Z value of all of those points so now we can actually take this output and the point cloud that drone a map produced and bring this into ArcGIS pros for some further processing inside of ArcGIS pro I brought my ortho mosaic in that was built out by Drona map and as we mentioned in the first part of this presentation one of the main interest was to see how this vegetation that didn't burn could potentially impact this transmission corridor in the future so I selected my ortho unclick imagery on the top I can actually go through and segment this imagery to find out where all of the canopy is in this image and after we've done that we get a great representation of exactly where all of this canopy exists and now I can actually take this and apply this to the point cloud to start classifying the points that drone am at built out so I'm going to turn over to a scene view so here you can see the 3d towers that drawn a map built out in terms of the points and we also have vegetation and so just by using the ortho mosaic and applying that classification to the points we now know where all the vegetation is inside of this scene and we can take arcgis pro and go a step further so we know where all the vegetation is but how could it impact the corridor itself in the conductor so here we actually use the 3d analyst tools to see where these points and this vegetation is within a certain distance from the conductor and lastly we can take all that data and share it up into a web browser so I have a browser open with no extensions this is just a native Chrome application and you can see I've shared the ortho mosaic into this and I can walk through this scene and actually share out the point cloud and millions of points to people across my entire organization so here we have the towers we can pan and zoom and share this again with anyone in the enterprise who needs to access this data and lastly we can share out those great analytical results that were built by pro so we can see exactly where the vegetation could potentially impact the corridor and the conductor across this area so you can see if there was a fire this year or next drona map helped us to look and see exactly where vegetation could potentially impact the conductor Thanks
