Geographic objects: Theory or technology driven?

This article aims to compare the geo-graphic (spatial) objects in 2D (planar objects) proposed by CON.G.O.O. and ISO standards, and the ability of a number of GIS software to handle them. The results achieved so far showed that the actual technical possibilities are not always sufficient to support the complex spatial objects proposed by CON.G.O.O.

The Role of LADM in Configurable Geographic Information Systems

Utilizing common language within industries has long been a successful pattern within geographic information systems (GIS) to assist in identification of suitable industry specific workflows. As technology itself advances, the need for highly accessible common industry language is even more pronounced. The Land Administration Domain Model (LADM)...

Aspects of Representing LiDAR Data Used for Updating

Performing environmental spatial analysis requires the collection of base data and special data, subject to the type of analysis in hand, among this data of course LiDAR data can be of much usefulness, in our particular case mobile network data were collected to assess the usefulness of using it for updating some features of the base map that...

Evaluation of an integrated GIS-based crime analysis & 3D modelling for Izmir-Konak municipality

GIS integrated 3D modelling is crucial for the city planning and design processes because urban modelling is a tool used in virtual environments, and provides convenience to work. Although, the creation and display of 3D city models for large regions is difficult it is vital for planning and designing safer cities, as well as public places....

Time use and movement behaviour of young people in cities: The application of GPS tracking in tracing movement pattern of young people for a week in Aalborg

LADM in the Cloud 1

New innovative cadastral projects are embracing satellite imagery and crowd sourcing, integrating disparate data sets, and leveraging all types of devices including smart phones and tables require new lightweight, easy-to-use technology for sustainable, reliable results. Technologies such as the cloud, appear on the surface to be unrealistic in...

Assessing people travel behavior using GPS and open data to validate neighbourhoods characteristics

With the help of technologies such as GPS tracks, GIS and open data is now possible to study people travel behaviour in a new way. Nowadays, large datasets can be easily handled thanks to databases and better visualized using GIS. Moreover, the availability of GPS data, open data and VGI makes accessible a lot of new information, which was not...

GIS-applications in landscape design and research

There is evidence that the potential of GIS is still underutilized in landscape design and research due to a lack of awareness and prejudice. This paper explores some concepts of GIS-based analysis which link to the very heart of landscape design in a natural and intuitive way. Hence the possibility to break down barriers of using GIS in...

Investigating the state of play of geoBIM across Europe

In both the Geographic Information (Geo) and Building Information Modelling (BIM) domains, it is widely acknowledged that the integration of data from both domains is beneficial and a crucial step in facing the multi-disciplinary challenges of our built environment. The result of this integration – which can broadly be termed GeoBIM –could...

Zooming into Socio-economic Inequalities: Using Urban Analytics to Track Vulnerabilities – A Case Study of Helsinki

The Covid19 crisis has highlighted once more that socio-economic inequalities are a main driver of vulnerability. Especially in densely populated urban areas, however, these inequalities can drastically change even within neighbourhoods. To better prepare for urban crises, more granular techniques are needed to assess these vulnerabilities, and...

Balanced Magnetic Antenna for Partial Discharge Measurements in Gas-Insulated Substations

Recent research has found that Magnetic loop antennas can detect partial discharges (PD) in gas-insulated substations (GIS); however, unbalanced shielded loop (UBSL) antennas are affected by electric field coupling. This research proposes a balanced shielded loop (BSL) adapted for GIS PD sensing with different designs. The frequency response and...
