Sentinel-5P Atmospheric Data Processing Begins

Sentinel-5P data open to the public, and Copernicus Atmosphere Monitoring Service (CAMS) has begun processing with detailed forecasts anticipated later in 2018. The Sentinels are a fleet of satellites central to Europe’s Earth-observation programme, Copernicus, addressing six main thematic areas: atmosphere, climate change, marine environment, emergency management, land and security. Atmospheric monitoring mission Sentinel-5P, the precursor to Sentinel-5, has just graduated from its official commissioning and validation phase, within which preliminary data was evaluated and instruments were calibrated. Early data was compared with the CAMS forecasting system, which allowed detection and solving of ‘teething’ issues. TROPOMI (Tropospheric Monitoring Instrument) gathers... (read more)

Topcon Announces Advanced Bentley Integration for Aerial Photogrammetry Processing

Topcon Positioning Group has introduced the new cloud-based photogrammetry processing powered by Bentley ContextCapture to its MAGNET Collage Web web-based service for the publication, sharing and analysis of reality capture data. The integration allows MAGNET Collage Web users who share and collaborate with scanning and mesh datasets to now process and add unmanned aerial vehicle (UAV or 'drone') photos directly to the MAGNET Collage 3D environment. The built-in Bentley ContextCapture Cloud Processing Service enables operators to upload UAV imagery direct-to-web without the need for high-end hardware requirements or IT constraints. Sharing UAV imagery projects “Operators with photos taken by any UAV will easily use the... (read more)

New Offline Post-processing Workflow for Trimble TerraFlex Software

The Trimble TerraFlex field software now supports the transfer of data between the field and office without the use of Trimble cloud services. The new software workflow – called offline data transfer – is possible through the integration of Trimble TerraFlex and the Trimble Positions Desktop add-in for Esri ArcGIS Desktop. TerraFlex is a field solution that enables mobile workers to easily collect, manage and edit their geospatial feature data. The new workflow provides an alternative to using Trimble cloud services for storing and transferring GIS feature data collected with the TerraFlex platform. In addition, TerraFlex field data collected via... (read more)

SimActive Adds Lidar to Point Cloud Processing Solution

In response to the growing use of Lidar, photogrammetry software developer SimActive has integrated a new Lidar workflow in its Correlator3D product. The capability enables users to import a point cloud in the software and to perform registration with an image dataset. Using Lidar as control eliminates the need for traditional ground control points (GCPs) during image processing. Registration occurs during aerial triangulation, leading to a precise alignment of imagery with the Lidar data. Following this, Correlator3D can output colourized point clouds as well as seamless orthomosaics. “Removing the need to manually tag GCPs facilitates the integration of Lidar data... (read more)

SimActive Further Accelerates Processing with New Version 8.4

SimActive, a world-leading developer of photogrammetry software, has announced the release of Correlator3D version 8.4 with significant accelerations. According to the Canada-based company, the new version leads to speeds that are multiple times faster compared to previous releases. Correlator3D 8.4 allows a dynamic allocation of hardware resources, reducing potential bottlenecks from PC components. For example, solid states drives (SSD) are used more efficiently by the software, as well as additional CPU cores and extra RAM. “While we were already way ahead with our processing speeds, version 8.4 further increases our advance”, said Louis Simard, CTO at SimActive. “Time is of...

Digitizing Reality: Automated 3D Point Cloud Data Processing Using AI

Intelligent Point Clouds
Instruments for digitizing the 3D real environment are becoming smaller, more lightweight, lower-cost and more robust. Accordingly, they are finding increasingly widespread usage, not only on surveying tripods for the highest accuracy, but also on mobile platforms such as autonomous vehicles, drones, helicopters, aircraft, robotic vacuum cleaners, trains, mobile phones, satellites and Martian rovers. Lidar uses laser scanning, while photogrammetry records images from one or more cameras which may be moving. Each laser scan records tens of millions of data point positions and colours in a point cloud, and hundreds of such point clouds may be combined. This article discusses... (read more)

Monitoring 3D Urban Growth

An Innovative Approach Integrating Lidar Processing with Machine Learning
Automated measurement of the third dimension of urban growth is a crucial requirement for future urban planning and monitoring. Airborne Lidar is increasingly being used to produce regular time-based data over metropolitan areas. However, the current solutions ignore the specific needs of urban planners, are complicated to run and fail to address the problem of monitoring 3D urban growth over time at building scale. To address the current challenges, two possible solutions have been developed into an integrated procedure. Urban planners want to automatically estimate all three dimensions and model the changes to buildings, the building footprints and absolute height... (read more)

Lidar Point Cloud Segmentation

A Novel Framework for Processing Terrestrial Lidar Data
Terrestrial Lidar data has great potential to produce measurements for as-built building information modelling (BIM). Unfortunately, processing hundreds of millions of points, often contaminated by substantial noise, can be tedious and time-consuming. Normal variation analysis (Norvana) segmentation is an automatic method that can segment large terrestrial Lidar point clouds containing hundreds of millions of points within minutes. Thanks to the high speed, point density and accuracy of modern terrestrial laser scanning (TLS), as-built BIM can be conducted with a high level of detail. But TLS captures not only useful geometric information but also unwanted objects, such as people, animals or... (read more)
