@USBR awards $6.6 million contract for photogrammetry to improve operations

The principal is exactly similar to plan table surveying, it may be stated as “The position of the object with ref to the base line is given by the intersection of the rays drawn to it form each end of the base line” In plane tabling most of the work is executed in the field while in this method it is done in the office.

Here’s the release from the US Bureau of Reclamation (Marlon Duke):

The Bureau of Reclamation awarded a $6.6 million contract to Geomatics Data Solutions, Inc. of Hillsboro, Oregon, for a 5-year agreement to provide agency-wide professional photogrammetry services, April 16, 2018.

Photogrammetry is the science of making measurements from photographs. Input is collected from photographs, such as aerial photographs, and used to create tools such as maps, drawings, measurements, or a 3-D models of real-world objects or scenes.

Geomatics Data Solutions, Inc. will provide high-resolution photogrammetry in support of technical evaluations conducted in all five Reclamation regions. These evaluations include historical analysis of aerial photography data, the creation of digital surface models and digital elevation models, thematic mapping of river planforms, bathymetric surveys, vegetation mapping, evaluations of land-use change, and the documentation of as-built site conditions for the monitoring of construction activities.

Initial photogrammetry work will be in support of Reclamation activities in the Upper Colorado Region, including sections of Wyoming, Idaho, Nevada, Utah, Colorado, Arizona, New Mexico, and Texas. Geomatics Data Solutions, Inc. may also perform work in Reclamation areas of responsibility throughout all 17 contiguous states west of the Mississippi River, during the contracted dates, as additional photogrammetry services are needed outside of the Upper Colorado Region. However, emergency response support will be limited to the Upper Colorado Region.

This contract will help enable Reclamation to carry out its mission to manage, develop, and protect water and related resources in an environmentally and economically sound manner in the interest of the American public.
