Abstract: A method for dynamic modeling of infrastructure projects over time, the method including receiving an infrastructure project design comprising: at least one of a three-dimensional view of an infrastructure project to be built and a set of two dimensional views of the infrastructure project; defining a plurality of design volume-surface-objects (DVSOs), repeatedly imaging the infrastructure project over time during construction thereof to produce multiple images acquired at a plurality of different times, automatically generating a point cloud representing the infrastructure project at each of the plurality of different times, automatically generating a plurality of as-built volume-surface-objects (ABVSOs), each of the ABVSOs corresponding to one of the plurality of DVSOs, and employing the ABVSOs and the DVSOs for constructing and managing the infrastructure project.

Abstract: For a field to be surveyed, generating at least first and second flight plans, the first flight plan including a plurality of first way points, the second flight plan including a plurality of second way points, each of the second way points corresponding to one of the plurality of first way points, each of the first and second plurality of way points being together suitable for photographing an entirety of the field to be surveyed; and executing, in parallel, the first and second flight plans by corresponding first and second drones, the executing including, at each of the corresponding ones of the first way points and the second way points, simultaneously photographing first and second at least partially overlapping sections of the field by corresponding first and second drones, obtaining an absolute position of each of the first and second drones, and measuring a distance between the first and second drones.

Abstract: A method for automatically validating measurements of a field survey including providing, on a field computing device, a two-dimensional image of a field to be surveyed, providing actual coordinates of at least two field reference points, each corresponding to an image reference point on the two-dimensional image, employing the field computing device to outline, on the two-dimensional image, features of interest of the field, employing the field computing device to manually select, on the outline, a plurality of image measuring points, for each image measuring point, identifying a corresponding field measuring point, measuring the actual coordinates of each field measuring point, thereby obtaining actual coordinates thereof, and responsive to the obtaining, automatically ascertaining for each image measuring point and corresponding field measuring point, whether there is a discrepancy between the location of the image measuring point on the two-dimensional image and the actual coordinates of the corresponding
