GIM International: March-April 2020

GIM International March-April 2020 cover

In line with tradition, the March-April issue of GIM International includes several articles on unmanned aerial vehicles (UAVs or 'drones'). Over the past years, UAVs have become a vital tool for the surveying and mapping industry. Equipped with a variety of sensors, they add a whole new dimension to the way we capture geospatial data. This edition of our magazine also includes a new article in our 'Ask the Specialist' series, in which relevant industry experts answer burning questions from GIM International readers – this time about UAVs.

This edition contains the following stories:

- How the New EU Directive Will Change the Geospatial Data Market
- GNSS Positioning at Centimetre Level for Dynamic Applications
- UAS Mapping – Where Is It Heading?
- The Main Issues to Consider before Using UAVs for Land Administration Projects

Using UAVs for Land Administration Projects

What Are the Main Issues to Consider before Using UAVs for Land Administration Projects?The almost ubiquitous UAV has been a key technology inspiring new thinking and disrupting land administration practice over the last decade. The flexibility and affordability of UAVs make them an efficient bridge between more expensive and time-consuming (but highly accurate) field surveys, and classical aerial or satellite photogrammetry. UAVs deliver tailored orthoimages from which spatial data – including visible parcel boundaries, building outlines and coordinates – can be derived. Many geospatial technology companies now offer high-tech UAV-based solutions, and many new hardware and software providers have also entered the market. Thanks to falling prices of UAVs, many land surveyors are now either experimenting with UAVs or already using them on a daily basis. So, what are the key questions that need answering before deciding to adopt a UAV in your next land administration project? Read on...

UAS Mapping

UAS Mapping – Where Is It Heading?The use of an unmanned aerial system (UAS) – cameras and Lidar sensors mounted on an unmanned aerial vehicle (UAV or ‘drone’) – to acquire geodata for mapping purposes has evolved beyond infancy and is now rapidly maturing. To envisage where exactly UAS technology is heading, it is appropriate to start with the big picture before examining the details. Read on...

Configure, Pleaseā€¦

COLUMN | Configure, Please…Having worked in land administration for many years, Esri's Bent Jones has seen all types of projects succeed and fail. We know the reasons for most of the failures – building an unsustainable and unscalable system, not understanding the total cost of ownership, poor system security, inadequate funding models, lack of local capacity, costly maintenance of custom-built software and many more. We can increase our chances of success by learning from these failures. Read on...

Authoritative Data in the Spotlight

Joep Crompvoets & Mick CoryThe European Union (EU) is adding a new dimension to the digital data-distribution policies of mapping agencies, cadastres and land registries. In two years’ time, a new EU directive will make it compulsory to provide open and free access to the most crucial, publicly funded geospatial and Earth observation data for use and re-use. EuroGeographics and EuroSDR, the two most renowned pan-European organizations in these matters, have reacted positively, assuming there will be sufficient national funding. After all, both society and the geomatics sector stand to benefit from increased use of ‘authoritative’ geospatial data. Read on...
