Digital Twins for Spatial Planning

Developing an Online 3D Model of the City of Groningen
The Dutch city of Groningen wants to follow in the footsteps of other cities such as Rotterdam, Hamburg, Singapore and Helsinki by developing a 3D digital model. For the team working on the 3D Digital City of Groningen project, the aim is for the image on the computer screen to be an identical replica of the reality outside. The City of Groningen in the Netherlands is committed to working in 3D whenever possible; in fact, its motto is ‘We work in 3D unless...’. The municipality’s City Engineers, City Design and Geo & Data departments are currently working together to develop... (read more)

Pix4D Launches New Ground Image Capture App for 3D Modelling

Pix4D has released a new app for ground imagery acquisition: Pix4Dcatch. The app has been developed to empower users to easily create ground-based 3D models using an iOS mobile device. Users don't need to be experts. They can simply scan the area of interest with Pix4Dcatch. The app records pictures along with GPS positions. Compatible with recent iOS devices, but optimized for the newest iPad Pro and iPhone 12 Pro and Pro Max with Lidar sensors, scanning is done with real-time 3D meshing for scene completion feedback. This process of giving live feedback enables a workflow that secures optimal results.... (read more)

SimActive Adds Multiple New Features to Correlator3D

SimActive has announced the release of Correlator3D version 8.6. The new version includes multiple new features, such as the use of intensity data from LAS files for image registration, the ability to improve mosaic seamlines with a DSM and the support of  DJI sun sensors. Based in Canada, SimActive is a leading developer of photogrammetry software. The software also now allows the handling of single-image satellite projects. Specifically, aerial triangulation can be performed using GCPs to improve georeferencing. External DEMs can then be used for orthorectification. “Feedback from our users is extremely important to us and drives our software development... (read more)

Bright Perspectives of Mapping from Above

Recent technological developments have made aerial surveying more exciting than ever. For imagery, ground resolutions of 2cm can now be reached, whereas for Lidar, pulse frequencies of 4GHz and point clouds of 30-40 points/m2 are no longer unusual. Simultaneous acquisition of imagery and Lidar is becoming increasingly popular. To optimize the production chain and improve the workflow, many survey companies are looking to artificial intelligence (AI) and deep learning (DL) as the holy grail. Given the impressive amount of training data available, the continuously better performing CPUs and GPUs and the many hours of research invested in this subject, there... (read more)

How to Use Mobile Mapping for CAD & BIM As-built Documentation

There is a general acknowledgement in the scanning and mapping industry that, compared to terrestrial laser scanners (TLS), mobile mapping systems significantly increase scanning speed and point cloud coverage. This is especially true for building interiors and equipment. This results in reduced time on site, which in turn lowers the cost of scanning for the service provider. There is a general acknowledgement in the scanning and mapping industry that, compared to terrestrial laser scanners (TLS), mobile mapping systems significantly increase scanning speed and point cloud coverage. This is especially true for building interiors and equipment. This results in reduced time on site, which in turn lowers the cost of scanning for the service provider. So why isn’t every scanning service provider switching from a TLS to a mobile system? The answer is that there is still a lot of hesitation concerning the data quality that mobile mapping systems can achieve, as well as uncertainty about which of... (read more)

Digitizing Hydrocarbon Storage Tanks

An Efficient and Safe Pre-maintenance Analysis
Carrying out essential maintenance on storage tanks can be complex. This case study outlines how a 3D topographic tank survey enabled identification of which areas of the tanks required maintenance. After capturing an image of the tanks with a laser scanner, the geospatial data was visualized, resulting in the full project as a digital twin. This project is an example of how technologies are changing the traditional approach to surveying techniques. The API Refinery of Ancona SpA is a petrochemical plant located along the Flaminia Route in the seaside resort of Falconara Marittima, Italy. Built on an area of 700,000... (read more)

Digital Technology as Leitmotif

In his latest column, Wim van Wegen reflects on digital technology as the leitmotif in Germany's role as a powerhouse within the geospatial industry. Traditionally, Germany is the heart of the geospatial industry at this time of the year, with Intergeo taking place in either September or October. The annual trade fair and conference is a major gathering of mapping and surveying professionals from all around the world. Due to the coronavirus outbreak, everything is different this year, and Intergeo was being held digitally from 13-15 October. For me, it felt almost surreal to not be travelling to Germany for...

VeriDaaS Plans Statewide California Lidar Mapping Project in Spring 2021

VeriDaaS is planning a high-density Lidar elevation data collection at a minimum of 30 points per metre (ppm) over the entire state of California in spring 2021 as part of the VeriDaaS National Mapping Initiative (VeriMAP). Higher density data above 30 ppm is also an option if stakeholder commitments are secured before the planned start of the project. The geospatial data will be utilized across a wide range of private-sector vertical markets including electric utilities, transportation, telecom, insurance, and architecture/engineering/construction (AEC), as well as Federal, State and Local Government groups. The California VeriMAP program is open to new participants. Private-... (read more)
