3D Cadastre

Semantic interoperability of distributed geo-services

There is an increasing need for organisations to perform on demand geoprocessing tasks by integrating and reusing distributed geo-information and geo-services (typically provided as services on the web, such as interactive maps, route planners and geometric transformations). To enable sensible integration, computers require to operate with...

3D topography: A simplicial complex-based solution in a spatial DBMS

Current topographic products are usually limited to a real world representation in only two dimensions, extended with some additional point heights and contour lines. Many environmental issues require more precision than analysis on 2D models can offer. At the same time, vast amounts of 3D data are becoming available due to emerging new data...

Variable-scale Geo-information

The use of geo-information is changing by the advent of new mobile devices, such as tablet-pc's that harness a lot of computing power. This type of information is more and more applied in mainstream digital consumer products, in a net-centric environment (i.e. dissemination takes place via the Internet) and the advances in mobile hardware also...

A domain model for land administration

75% or the “people to land relationships” worldwide are not documented. This concerns about 4.5 billion cases. With a growing population this situation results in land disputes, land grabbing and neglecting of rights of local people. Land Administration provides documentation on people to land relationships. Land Administration is an instrument...

Development Methodology for an Integrated Legal Cadastre

This Thesis describes the research process followed in order to achieve a development methodology applicable to the reform of cadastral systems with a legal basis. It was motivated by the author’s participation in one of the first surveying and mapping operations for a digital cadastre in Portugal, and the problems faced by the cadastre, and...

Path planning for first responders in the presence of moving obstacles

Navigation services have gained much importance for all kinds of human activities ranging from tourist navigation to support of rescue teams in disaster management. However, despite the considerable amount of route guidance research that has been performed, many issues that are related to navigation for first responders still need to be...

Design and development of a system for vario-scale maps

Indoor Semantic Modelling for Routing: The Two-Level Routing Approach for Indoor Navigation

Humans perform many activities indoors and they show a growing need for indoor navigation, especially in unfamiliar buildings such as airports, museums and hospitals. Complexity of such buildings poses many challenges for building managers and visitors. Indoor navigation services play an important role in supporting these indoor activities....

4d open spatial information infrastructure: Participatory urban plan monitoring in indonesian cities

An urban plan contains a set of agreements from all stakeholders that may directly impact livelihood. However, many cities show a ‘plan and forget’ behavior by not monitoring and evaluating their urban plans. While local citizens are often excluded after the urban plan is enacted. Gibbs (2016) warned of the risk of this behavior by saying, ...

The ­Integration of LADM and IndoorGML to Support the Indoor ­Navigation Based on the User Access Rights

Indoor navigation applications are actively investigated and developed due to their capacity to provide users with essential information in the modern extensive building complexes. Therefore, many researchers have developed a range of indoor navigation applications, which have focused on aspects such as localization, indoor route computation,...

nD-PointCloud Data Management: continuous levels, adaptive histograms, and diverse query geometries

In the Geomatics domain, a point cloud refers to a data set which records the coordinates and other attributes of a huge number of points. Conceptually, each of these attributes can be regarded as a dimension, representing a specific type of information. Apart from routinely concerned spatio-temporal dimensions for coordinates, other dimensions...
