OpenDroneMap is an open source photogrammetry toolkit to process aerial imagery (usually from a drone) into maps and 3D models. [3] [4] [5] The software is hosted and distributed freely on GitHub. [6] OpenDroneMap has been integrated within American Red Cross's in-field Portable OpenStreetMap system. [7]
Pictometry is a patented aerial survey technique for producing oblique georeferenced imagery showing the fronts and sides of buildings and locations on the ground. Photos are captured by low-flying airplanes, depicting up to 12 perspectives (shot from a 40-degree angle) as well as an orthogonal (overhead) view of every location flown.
For most of the Sudbury Aqueduct's history after the Sudbury Reservoir was built the water was primarily sourced from the Foss Reservoir which the Sudbury Reservoir feeds with Reservoirs #1 and #2 serving as reserve supply due to the Sudbury Reservoir's superior water quality over the Reservoir #2 system.
