UAS-supported Agriculture: Still for Innovators

Greatest Potential on Small Farms
While unmanned aerial systems offer huge possibilities in modern farming, most of them lie in the future. These airborne vehicles currently mainly deliver images that are subsequently combined with other input in the farm-specific management system. In the future they will be able to contribute to land management and individual crop-product delivery based on real-time analysis. Another very promising segment for UAS-supported precision agriculture is water management. Precision agriculture is a relatively young concept, dating from around the turn of this century. The first products were focused on add-on guiding systems for tractors. These give a good return on investment,... (read more)

The Conference Venue: University of Twente Campus

The ISPRS Geospatial Week 2019 will be held on the University of Twente campus. The University of Twente (UT) is the only university in the Netherlands with a genuine campus. It is set in extensive parkland that houses buildings for education and research, facilities for sports and culture, student and staff accommodation and a shopping centre. The ISPRS Geospatial Week will take place in some of the buildings on the so-called ‘O&O plein’ (‘Education & Research Square’), such as the Hal B/Waaier and Carré buildings. The buildings on the O&O plein are located close together, connected by pedestrian walkways. In... (read more)

Data Modelling for Water Management

UML for Better Communication among Stakeholders
In 2004 the government agency responsible for water management in The Netherlands began a project to create an integrated geo-database for holding all geo-information on water-related objects. The set-up of the geo-database had to be sufficiently flexible for use at different management levels and geo-data had to be accessible using Web services. UML has played an important role in the project: it helps discussions, forcing designers and end-users to be specific. Because of its geographic location in a low-lying delta, water management is of prime import-ance for The Netherlands. Rijkswaterstaat (RWS), the Directorate-General for Public Works and Water Management, is... (read more)

FIG Working Week - What’s Next?

It is Thursday 14 May 2020, and today should have been the closing day of FIG Working Week in Amsterdam. The programme of today would have been the second General Assembly session and closing ceremony. Also a comprehensive tour, 'Dutch land and water management', was scheduled to take place today. The intention of the tour was to give a unique insight into the Netherlands, with a focus on how water has shaped spatial planning and development in the Netherlands. It should have taken attendees on an exclusive journey using various modes of transport, starting at the historical Fort Vechten and... (read more)

Land Challenges in a Revolving World

FIG Commission 7: Cadastre and Land Management
Has your world changed in the last four weeks? It has for Commission 7 also, and we are adjusting quickly to the new needs of our world. Commission 7 is about the relationship between land and people, and how surveyors and other professions support nations to administer their land resources. During this pandemic, every day the COVID19 virus is changing how we relate to our land from border closures to restrictions to citizens to be confined into private parcels. The current pandemic has shown how important it is to have a land inventory (the cadastre), and to be able to... (read more)

Against the ‘How to Lie with Data’ Classification

New Task-oriented Methods for Designing Choropleth Maps
Choropleth maps are widely used for presenting population density, social index or other normalized statistical values related to spatial units. One of the ‘white spots’ on the research and development ‘map’ of cartography is that conventional methods for creating choropleth maps are data driven and may lose extreme values or small clusters of extreme values (hot spots) due to an unfavourable setting of class breaks. In this article, the author presents a new method and evaluation measures which enable better preservation of important spatial characteristics. The methods and software implementation result from the aChor project. The choropleth map is a... (read more)

Web-enabled GIS in Disaster Management

A Disaster Hazard and Vulnerability Atlas for SA
Increasingly frequent disasters with attendant damage have heightened climate change related environmental and social vulnerability, emphasising the need for tools to support disaster management. In South Africa a National Disaster Hazard and Vulnerability Atlas has been developed using Web-enabled GIS as the primary user interface. The disaster, hazard and vulnerability ‘Atlas’ which is operational today in South Africa is a virtual book consisting of various chapters, such as drought, flood, cyclones, storms, severe weather, and fires. The Atlas enables users: to search and select data, images, maps and graphs to perform calculations to run models on the fly to copy-paste... (read more)

Geomatics at TU Delft

Developments in Geomatics Education (6)
Collecting, processing, managing and distributing information and transforming it into relevant support for decision making constitutes the nerve system of society at local, regional, national and global scale. Of increasing importance is information bound to certain locations at, above or beneath the surface of the earth. The tools, techniques and theoretical background for acquiring, processing, managing and disseminating geo-information constitute the discipline of Geomatics. TU Delft expertise in geomatics originates from a long tradition of education in Geodesy offered over fifty years at both BSc and MSc level until 2004. Since 2005 Geomatics at TU Delft has been offered as... (read more)

Use of GIS in Smart City Projects

Managing and Visualising Geospatial Data in a User-friendly Environment
A geographic information system (GIS) has been used in the construction of a large-scale model of a smart city project in France. The smart city concept is developing very quickly around the world, because it provides a comprehensive digital environment that improves the efficiency and security of urban systems and reinforces the involvement of citizens in urban development. This concept is based on the use of geospatial data concerning the urban built environment, the natural environment and urban services. The successful implementation of a smart city project requires the development of a digital system that can manage and visualise the... (read more)

SoftGIS Methodology

Building Bridges in Urban Planning
The Finnish innovation SoftGIS refers to a collection of internet-based surveys which allow the locality-based study of human experiences and everyday behaviour. SoftGIS enables the combination of ‘soft’ subjective data with ‘hard’ objective GIS data. Large datasets can be collected for the use of urban planners and other professionals interested in the development of more user-friendly physical settings. SoftGIS received the Technology Innovation Award for Web GIS at the 2011 Geospatial World Forum in Hyderabad, India, and is soon to be applied to urban areas in Japan and Australia. It has long been the ambition of the first author that... (read more)
