3 H2H s Land and Water Based Mobile Mapping Equipment Land Based Mapping - Land based mapping shown is a truck mounted laser scanning system to rapidly pick up survey points in a 360 field of view Marine Based Above and Below water Mapping - Marine system couples laser scanning mounted on the truck with high resolution multibeam sonar Indoor, Undercover and Underground Mapping - Indoor and underground mapping allows for highly accurate mapping in below ground areas or under cover areas that can be accessed by foot 3

4 H2H S Static Mapping Hardware GPS Total Stations High Definition Laser Scanning Terrestrial Photogrammetry 4

5 Land Based Mobile Mapping Primary Components Portable Laser Scanner Digital Camera Internal IMU Internal GPS GPS Base Station/VRS Internet connection Rugged All weather mapping!! - A typical land based crew on site to collect physical inventory data - Truck mounted Mobile laser scanning - GPS used to determine boundaries and as an independent qa qc check - Can be used in all weather conditions 5

6 Types of Mobile Mapping (Terrestrial) View data while surveying Ensure all data that is necessary is collected Validate results visually and through quality assurance algorithms Latest tools can survey at 60 mph with 2cm accuracy View from the control system during mobile mapping

7 Vehicle Mobile Mapping (point cloud colorized by elevation) Example 3D fully colorized point could of a stockpile yard. H2H completes physical inventories (aggregate, salt, industrial minerals, wood chips, dredged material, etc.) 150 sites, 5,000 piles/yr Materials valued over $250 million Repeatability of pile <1% 10 states Utilize 4 mapping tools 7

8 3-D MODELS OF STRUCTURES 8

9 H2H s Aerial Mapping Equipment Quad Rotor Wing Aerial Mapping (UAS) 2 - Fixed Wing Aerial Mapping (UAS) - Aerial mapping allows for a drone to fly a site and gather survey and photo data from the air 9

10 UAS Mobile Mapping (Components) Primary Components 20 mp Digital Camera or Thermal or Multispectral Camera Internal IMU Internal GPS Laptop for flight plan development and inflight tracking High-end computers for post flight processing FAA Exemption for commercial laws Apply to aircraft under 55lbs Must maintain visual line of sight (unaided) May not operate over anyone not directly involved in the operation Daylight only Max speed of 100mph Max altitude of 400 ft Must obtain knowledge certification - Aerial mapping with the drone uses similar components as land and water based. The IMU, GPS are at the heart of the system - Photos are collected and post processing software is utilized to create orhtophotos and digital surface model 10 - Highly weather dependent dark, windy, rainy conditions can hamper a project

11 UAS Mobile Mapping potential data sets Geospatially referenced images, x,y,z coordinates and Red Green Blue (RGB) 3 band Standard RGB data that allows for real color renderings High resolution near infrared (NIR) 3 band Red, Green and NIR bandwidths Commonly used to evaluate plant biomass, plant health Red Edge (RE) 3 band Provides blue, green and red edge band. Commonly used to evaluate stress, chlorophyll concentration Thermal Captures thermal image and videos Commonly used to map water distribution, impacts of shading Multispectral (MS) 4 band Provides, green, red, red edge, and NIR with no overlap Multispectral visible and non visible spectral bands plus RGB 11

12 UAS Mobile Mapping (Flight Planning) Pre plan flights Simulate flights Actual flight path controlled by GPS way points Photos taken automatically o Flight paths are loaded into controller software o Flight area viewed in real time on computer screen o Progress is monitored in real time 12

13 UAS Mobile Mapping (Post Processing) 1. Multiple overlapping and geotagged images are imported into software 2. Images are stitched together 3. Ground location points are imported 4. Millions of 3D measurements are made 5. Output (Dense 3d pointcloud and orthophoto) 13
