Taking Full Advantage of the Benefits of UAS Technology

Leveraging UAS technology across surveying and engineering sectors is demanding. The expectations of accuracy and accountability requires the best in expertise, methodology and equipment. Using the latest unmanned aerial system (UAS) photogrammetric hardware and software, surveyors are now capturing millions of survey measurements on the ground, where they would previously have measured only hundreds. It is essential to have the best-quality equipment, software and workflows to ensure this data is accurate, robust and defensible for professional use. Geosyntec is a leading consulting and engineering firm that works with private and public sector clients to address new ventures and complex problems... (read more)

SimActive Introduces New Drone Processing Service

Canadian photogrammetry software manufacturer SimActive has launched a new unmanned aerial vehicle (UAV) data processing service based on Correlator3D. Clients can now upload full projects and have SimActive experts generate optimal results from their imagery, including DSMs, DTMs, 3D models and orthomosaics. As opposed to common cloud-based solutions where outputs are generated automatically and delivered as-is, the new offering includes quality control by photogrammetry specialists. Manual tagging of ground control points is also performed as part of the service. “We are glad to allow clients with no experience in photogrammetry an access to a high-end processing software”, said Dr Philippe...

Sensor Fusion for Precision Agriculture

Low-cost Lidar Camera System without GNSS
Precision agriculture has considerably benefited from the use of unmanned aerial vehicles, often combined with active ranging sensors like Lidar to gather information from underneath the crops, but existing systems are relatively expensive for the farming sector. In this project, researchers in Canada have used an integrated sensor orientation method for the local referencing of Lidar measurements. Their approach is based on loosely coupled, image-aided inertial navigation in which the pose of the camera replaces the GNSS measurements. The result is a low-cost solution that is useful for capturing topographic data of inaccessible areas as well as in GNSS-denied environments.... (read more)

Geoinformation Software as a Service

From Licensing to Subscription
Accurate geoinformation about urban areas, public buildings or historical sites is in great demand. It has become astonishingly easy to capture these scenes through cameras or laser scanning or to acquire open data from a diversity of sources. Professionals without a surveying background can do the job, but such professionals require reliable, robust, easy-to-use and affordable processing tools. Today, cloud computing can meet that need, enabling users to work with software packages running on remote servers on either a pay-per-use or a subscription basis. This article presents a cloud computing service dedicated to geoinformation software. Storing data in the cloud... (read more)

Mapping a University Campus in Brazil

Creating Indoor and Outdoor Maps for a Routing Application
At universities, facility managers and other support staff need easy access to data, including geodata, for maintenance, safety measures or routing of students, staff and visitors. A responsive geodatabase containing detailed and up-to-date information on roads, the interior and exterior of buildings and other objects is a key tool in that context. The authors of this article describe a pilot project conducted at a university campus in Curitiba, Brazil, aimed at creating outdoor maps using unmanned aerial system (UAS) photogrammetry as well as indoor floor plans, and demonstrate the possibilities of the database with a routing application. The Federal University... (read more)
