How Geospatial AI Leads to Smart Urban Ecosystems

The possibilities of geoAI for monitoring Mother Nature are limitless according to Dr Nadina Galle, ecological engineer and entrepreneur dedicated to applying emerging technologies. The use of satellite imagery to manage the health of trees in cities improves urban ecosystems. By combining traditional methods with other geospatial technologies, such as remote sensing, and artificial intelligence to achieve ‘geoAI’, it is possible to detect and classify features even faster and more accurately. GIM International spoke to Dr Nadina Galle, an award-winning ecological engineer and entrepreneur dedicated to applying emerging technologies, to learn more about the seemingly limitless possibilities of geoAI.

Qatar University Launches Digital Qatar Project

Qatar University (QU) has unveiled plans for the Digital Qatar Project. Drone imagery will be used for the purposes of aerial surveying at QU, with the participation of specialists from Qatar and international experts in the field of two-dimensional surveying. The project is being run by the university’s College of Engineering (QU-CENG) and is sponsored by Dolphin Energy. Hassan Al-Emadi, Dolphin Energy’s general manager for Qatar, stated: “Investing in modern technologies will not only be of great value to the university’s faculty, students and experts, but will also help provide a digital infrastructure that will drive cultural change. Digital transformation... (read more)

Establishing an Accurate Geodetic Reference Network for Uganda

Facilitating Cadastral Surveys, City Developments and Road Construction
In line with the United Nations resolution to adopt a global geodetic reference network, the Government of Uganda received financing from the World Bank towards the cost of a competitiveness and enterprise development project. As part of this, Fugro was commissioned to design and implement a modern, reliable and accurate national geodetic reference network for the whole country, in addition to the deployment of a national continuously operating reference station (CORS) network. Effective management of land resources is of vital importance to the Government of Uganda in order to support the country’s development and reduce poverty. The improvement of the... (read more)

UAV Photogrammetry as an Alternative to Classic Terrestrial Surveying Techniques

Why are UAVs increasingly supplementing or even replacing terrestrial survey methods for many applications? This article explores the advantages of photogrammetric mapping with UAVs. Unmanned aerial vehicle (UAV or 'drone') mapping often uses photogrammetry to generate accurate, real-world 3D models from 2D imagery. By combining and processing multiple georeferenced aerial images, photogrammetric techniques are used to generate outputs such as 3D point clouds, raster digital elevation models, and orthomosaics. One of the biggest advantages of photogrammetric mapping with UAVs is that it allows land surveyors to accomplish more in less time. Surveying jobs that would typically take weeks to complete...

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)

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)
