2 Who we are The Western Utility Group was established 30 years ago. Since moving into locating over 15 years ago, we have built valuable relationships with dozens of major utilities and engineering firms, as well of hundreds of private clients. Our goal is to continue to innovate and provide cutting edge products to our clients

3 Topics to Cover How we do aerial photography What are the end benefits to our clients

4 Methods of Aerial Photography Introduction and Advantages of the Quadcopter and the Telescoping Mast How We Capture Data How We Combine the Data Advanced Capabilities

5 Telescoping Mast Data

6 Aerial Photography: Telescoping Mast Easily controlled and highly portable Has less deployment restrictions than the quadcopter. Height up to: 70ft / 21.35m Higher resolution camera

7 Telescoping Mast Data Photos taken from a bird's eye view Multiple photos taken in sequence Photos stitched together to create large mosaic Photos and offsets enhanced in post processing

8 Telescoping Mast Data Mosaic gives large overview of underground utilities Useful for planning Very high resolution of mosaic allows user to zoom in with greater detail

9 Telescoping Mast Data Low-res satellite map provides background for mosaic Allows user to better understand location surroundings

10 Telescoping Mast Data: Examples

11

12 Aerial Photography: Quadcopter Staff trained and certified with Restricted Radio Operator's Certificate (required to fly by Transport Canada) We meet all guidelines set in place by Transport Canada

13 Quadcopter Data Permitted to fly up to 300 feet Greater field of view Camera is of a lesser resolution than the mast

14 Quadcopter Data Larger projects can be easily completed with multiple photos Photos are stitched together in post processing

15 Quadcopter Data Markers enhance the underground utilities so they can be more easily distinguished Post processing increases visibility

16 Quadcopter Data Post-processing enhances the visibility of the offsets Clients can easily find underground utilities after paint has faded

17 Quadcopter Data: Example X3

18 Quadcopter Data: Example X2

19 Quadcopter Data: Examples

20 Quadcopter Data: Examples Drone Data and Mast Data merged

21 Quadcopter Data: Examples Drone Data and Mast Data merged

22 Quadcopter Data: Examples Drone Data and Mast Data merged

23 How We Capture Data Telescoping Mast No government restrictions Smaller field of view, more setup time Requires more post-processing to account for distortion Quadcopter Requires certification and has flight restrictions Wider shots

24 Advanced Capabilities Introduction Orthomosaics Point Clouds

25 Quadcopter Advanced Data Data can be turned into geo-referenced 2D and 3D models

26 Quadcopter Advanced Data Geo-referenced orthomosaics can be outputted in many formats: DSM, DTM, CAD, textured 3d models, point clouds

27 Quadcopter: Elevation Data Drone data can be processed to supply client with geo-referenced elevation profiles

28 Quadcopter: Elevation Data

29 Quadcopter Data: Orthomosaics Example from earlier Combination of 3D point cloud with original images Underground utilities are marked out by creating polylines

30 Quadcopter Data: Orthomosaics Geo-referenced Polylines can be exported into many different formats Formats include: ESRI Shapefiles AutoCAD DXF Keyhole Markup Language(KML) Microstation DGN

31 3D Point Cloud: Western Locates example

32 3D Point Cloud : Mission example

33 3D Point Cloud: University example

34 Quadcopter Data: 3D Point Cloud All geo-referenced data can be used to measure offsets digitally Underground utilities can be relocated with much more accuracy

35 Benefits To Our Clients Damage Prevention Planning Legal Documentation

36 Damage Prevention-Site Sketches Client may have problems interpreting sketch Sketch may miss crucial details Not nearly as good as a photograph

37 Legal Documentation Picture of line hit

38 Legal Documentation Picture of original locate

39 Legal Documentation Picture of line hit

40 Legal Documentation Picture of original locate

41 Legal Documentation Picture of line hit

42 Legal Documentation Picture of original locate

43 Damage Prevention-Aerial Photograph 100% accurate data of the locate and the work area Less interpretation for client

44 Damage Prevention-Aerial Photograph Aids in damage investigation Prevents unscrupulous clients from repainting lines Court Ready Legal documentation

45 Planning Clients will get to see recent photo, compare their proposed work to what s actually in the ground
