One of the essential components for the construction of a geographic spatial data infrastructure at a regional, national or global level is the geographic information catalog server. But, for the catalog to be a useful component, it must enable access to geographic information metadata independently of the nature of search client applications, in other words, client applications do not need to ...

<span lang="EN-US">Human activity detection is a research field that has been growing rapidly for the last few decades. It opens wide of applications in fields healthcare, smart homes, robotics, human-media interaction, surveillance and security. WiFi-based solutions have received lot attention lately. These are based on idea nearby wireless signals affected by human bodies. Reflections p...

The paper analyses the requirements on automated generalisation when applied in the context of an existing multiple-resolution data infrastructure, where the small scale data sets should not be replaced but kept and updated incrementally. The situation is explained by example of the official German topographic-cartographic information system ATKIS.

In this paper, a status report on China's national information infrastructure (CNII) and its development progress is introduced. The main goal of the CNII is to accelerate the economic development by means of information technology (IT). Based upon the modern information technologies, the CNII is designed as the nationwide three dimensional information communication network to streamline inform...

For numerous spatial applications, land use data are of central importance and have to be available in a spatial data infrastructure for regional modeling, according to the international data standards. This also counts for the research project TR32 which focusses on SVA modelling in a regional context. Especially for (agro-)ecosystem modeling the information content of the available official l...
