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. You have developed a method to determine the health of trees in cities using s... (read more)

BeeMobile Case Study: Mobile Mapping with Faro Laser Scanner

BAM Infra recorded 3D road models using a Faro terrestrial laser scanner with the innovative BeeMobile mobile mapping system at various locations across the Netherlands in 2020. BAM Infra is part of the BAM group and is active in the domestic market of the Netherlands and other European countries. As a leading and innovative company, BAM is constantly looking for improvements and innovations to optimize business processes. An essential part of the infrastructural business process within BAM is the geodetic field in which various specialists use their specialist knowledge to serve both internal and external customers as well as possible. Traditional equipment such as tachymeters, GNSS receivers, static scanners and drones have been used on a regular basis for five years. However,... (read more)

Multiplatform Lidar Use in Digital City Projects

Following its emergence more than a decade ago, digital twin technology has developed to become a complex and comprehensive technical system that supports the construction of new smart cities. It is also an advanced model for the continuous innovation of intelligent urban development and a future form of modernization of the combined ‘virtual and real’ world. (This article is brought to you by CHCNAV) The establishment of the digital twin city brings to the forefront high-level topographic tools that are able to deliver comprehensive, multi-dimensional, large-scale and high-resolution datasets. Traditional methods of collecting and representing 2D spatial data, such as maps and images, are no longer sufficient, and a complete upgrade of traditional surveying tools is required....

Integrating Robotics into the Construction Surveyor’s Workflow

How are robots and autonomous technology likely to affect surveying roles as they become increasingly integrated into workflows? With great possibilities come great responsibilities, and this is particularly true for the role robotics and autonomous technology can play in our world. Over the course of time, technological possibilities have drastically changed the face of many jobs in surveying, construction and geospatial applications. Since the 1990s, for example, robotic total stations have resulted in an enormous leap in productivity by making it possible for an operator to carry out a site survey alone thanks to automated rotation and tracking of the prism. With robotics and autonomy becoming increasingly pervasive, combined with disruptive developments like the Internet of Things (IoT... (read more)

Establishing an Accurate Geodetic Reference Network for Uganda

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 land administration system, directly linked to developing the agriculture, mining and construction sectors in Uganda, is one of the... (read more)

Unlocking the Full Potential of UAVs for Advanced Mapping

In this edition of ‘Ask the Specialist’ the question is: how can we unlock the full potential of drones for advanced mapping operations? For our ‘Ask the Specialist’ features, we invite readers to send us their burning questions about geospatial surveying. We pass the questions on to relevant industry experts who provide comprehensive and detailed answers to point geospatial professionals in the right direction. It is no secret that, today, unmanned aerial vehicles (UAVs or ‘drones’) are a viable and mainstream commercial mapping tool that provide a robust return on investment. But technology does not stand still, and the result is the progress of more advanced drone operations which can help to improve safety for people both in the air and on the ground... (read more)

The First-ever Online-only UN-GGIM Session

The United Nations Committee of Experts on Global Geospatial Information Management (UN-GGIM) gathered for its Tenth Session in the shape of three two-hour informal meetings on 26 and 27 August and 4 September, albeit only ‘virtually’. The event was originally scheduled to be held at the United Nations Headquarters in New York, USA, at the beginning of August. When the COVID-19 restrictions made it impossible for delegates to travel, the session was postponed and rescheduled. Thanks to all the IT preparations made by the Secretariat, the Tenth Session successfully became the organization’s first-ever online-only session. The Committee of Experts actually had their first successful experience of a virtual meeting in the run-up to the Tenth Session, when the Sixth High Leve... (read more)
