Airborne Lidar Production Fully Integrated with Leica HxMap Workflow

Leica Geosystems has released the Lidar data processing capability in the Leica RealCity solution package and partnered with international asset integrity and geo-intelligence solutions provider, Fugro, to begin acquiring and processing data over multiple cities and coastal regions across the United States. Using CityMapper, Fugro conducted aerial surveys over some of North America’s most densely populated urban centres, in support of their geospatial mapping services. As the world’s first hybrid airborne sensor combining oblique and nadir imaging as well as a Lidar system into one instrument, the CityMapper enables significant time and cost savings by flying once to collect both...

Producing High-quality 3D Point Clouds from Structure-from-Motion Photogrammetry

How to Produce High-quality 3D Point Clouds
Anyone involved with structure-from-motion (SfM) photogrammetry has probably questioned which type of processing software is necessary for them to produce quality 3D point cloud data. Many SfM software packages exist that allow for the generation of 3D point clouds from image sequences acquired via unmanned aerial systems (UASs). Each of these software packages provides different workflows and parameters for implementation of SfM processing and for point cloud densification using multi-view stereo (MVS) algorithms. To examine the influence of terrain on the results, this study compares differences in point clouds generated by three different types of SfM software.  It is well... (read more)

Leica Announces True Tilt-compensating GNSS

Leica Geosystems has announced the Leica GS18 T, which it describes as the world’s fastest GNSS RTK rover and the first calibration-free tilt-compensating GNSS solution immune to magnetic disturbances. In a further expansion of the Leica ‘Captivate Experience’, the company is also introducing the latest versions of Leica Captivate field software and Leica Infinity office software. The GS18 T enables GNSS measurements to be taken from any position on site. This saves users up to 20 percent of time in the field over conventional surveying practices as the pole no longer needs to be held vertical to level the bubble.... (read more)

New Solution for Accurate Aerial Mapping and Inspection

4DMapper has partnered with Verity Positioning to offer Verity Cloud, an end-to-end solution for high-accuracy mapping. It offers streamlined photogrammetry processing on Autodesk Forge, a cloud developer platform, delivering unmatched quality in 3D maps and models. 4DMapper, an established provider of cloud hosting and streaming services for geospatial data, has enabled this collaboration via API integrations as an example of how geospatial products can be leveraged on the cloud. Verity Positioning, a powerful PPK geo-referencing hardware/software solution, enables high accuracy mapping without the need to place ground control points. The system uses a sophisticated proprietary methodology for camera positioning, calibration... (read more)

Vertical Technologies Launches New VTOL UAV

Vertical Technologies has released its DeltaQuad series of autonomous VTOL UAVs. This hybrid vertical-take-off fixed-wing UAV can stream telemetry and video over the cellular network using VPN, and boasts a 1kg payload capacity, flight time of 2 hours 45 minutes and 150km range. The DeltaQuad is developed by members of the PX4 Pro autopilot development team and uses several innovative features that aims to make this UAV as easy to control as setting up a navigation system. It requires no pre-flight calibrations and the Pro model comes equipped with an on-board computer that almost completely replaces the operator, making the... (read more)

UAV-based Mobile Mapping: Potential, Challenges and Outlook

A Cost-effective Alternative to Airborne and Terrestrial Modalities
Accurate representation and 3D reconstruction of the environment using both active and passive remote sensing systems has become essential for non-traditional mapping applications. Due to the excessive cost as well as the required level of technical expertise, the needs of these applications cannot be satisfied by traditional mapping, which is based on dedicated data acquisition systems designed for mapping purposes (e.g. manned airborne and terrestrial mobile mapping systems). Recent advances in hardware and software development have made it possible to conduct accurate 3D mapping without using costly and high-end data acquisition systems. Low-cost digital cameras, laser scanners and navigation systems... (read more)

Looking Back: The ISPRS Hannover Workshop 2017

The ISPRS Hannover Workshop 2017 took place from 6-9 June 2017 in Germany. It was hosted by IPI, Leibniz Universität Hannover with four workshops under its roof: High Resolution Earth Imaging for Geospatial Information (HRIGI17), City Models, Roads and Traffic (CMRT17), Image Sequence Analysis (ISA17) and European Calibration and Orientation Workshop (EuroCOW17). HRIGI and EuroCOW deal with more geometric topics, while CMRT and ISA have a legacy in automatic scene understanding, object reconstruction and trajectory computation. The event was sponsored by Leica Geosysystems (Gold Sponsor), Geonumerics, IGI, Luxcarta, Pix4D and Vexcel. 57 full papers and 121 abstracts were submitted to... (read more)
