Clear Scanning on the Clearwater
Above: The survey included collecting bathymetric data on the river bottom and bridge substructure with multibeam sonar as well as capturing above- and below-waterline mobile mapping data with the Leica Pegasus: Two mobile sensor platform. Two well-paired engineering firms used high-accuracy mobile mapping to combine bathymetry and lidar data for a fast-turnaround topographic survey of...
6D SLAM
An indoor spatial intelligence start-up from Germany is pushing the BIM industry forward through a combo of navigation and visualization. The line of people at the Intergeo Trade Fair in Frankfurt, Germany, waiting to get their hands on the NavVis M6 was long. Where everyone was on the lookout for the latest geospatial products on...
Walkaround Mobile Scanning Part 1
Above: Walkaround mobile scanning is being increasingly used as a go-to tool for as-built surveys of residential properties as an input to remodel design. Credit: Precision Property Measurements. Part 1: Basic types, differences, and advantages. Walkaround mobile scanning includes “backpack,” “push-cart,” “hand-carry,” and “handheld,” but whatever you call it, it’s gaining real momentum in the...

BLK2GO SLAM (simultaneous localization and mapping) lidar handhelds have become popular for BIM, as-builts, and rapid 3D modeling. The new Leica Geosystems BLK2GO shares some of the core technologies of earlier members of the BLK family (like the BLK360 scanner). What distinguishes this from many of the other SLAM handhelds is that it utilizes cameras...
Accuracy with a Phone?
Photogrammetry is now possible using consumer devices, and the applications are vast. Continuing improvement in digital cameras—including those in cell phones—and in photogrammetry algorithms have enabled dozens of consumer and professional photogrammetric applications. Among the professional ones is PhotoModeler, which produces accurate maps, drawings, CAD data, 3D models, and photos draped on 3D models. Its...
Many Sensors for a Tulip Tree Map
Above: The forests of Puerto Rico are second-growth, making for useful modeling. After hurricane deforestation in Puerto Rico, NASA scientists study forest regrowth using high-resolution, multi-sensor image data. The Biospheric Laboratory of the NASA Goddard Space Flight Center is dedicated to increasing knowledge about the Earth’s terrestrial ecosystem. One group of scientists there has been...
