In the past decades a wide range of complex processes have been developed to solve specific geospatial data integration problems. As a drawback these complex processes are often not sufficiently transferable and interoperable. We propose modularisation of the whole data integration process into reusable, exchangeable, and multi-purpose web services to overcome these drawbacks. Both a high-level...

Investigations on the use of stereo GEO and multitemporal GEO Ikonos images for DSM generation are reported. Both an own developed matching algorithm and the digital photogrammetric systems LH Systems DPW770 and VirtuoZo were used. In our own matching method, we start with quasi-epipolar image generation, and derivation of approximations using grid point matching based on relaxation. The final ...

This paper gives an overview of the potential of the current implementation of portable components for Geoscientific Information Systems (GIS) within the GISIG actmap-project. The computing problems addressed are multifold and for the first time presented here: With Active Source having extended the framework for conventional GIS, new features have been enabled like the use of Grid Computing an...

Georeference is a basic function of remote sensing data processing. Geo-corrected remote sensing data is an important source data for Geographic Information Systems (GIS) and other location services. Large quantity remote sensing data were produced daily by satellites and other sensors. Georeferenceing of these data is time consumable and computationally intensive. To improve efficiency of proc...

The smart grid must ensure that power providers can obtain substantial benefits by selling energy, while at the same time, they need to consider cost of consumers. To realize this win-win situation, relies on dynamic pricing mechanisms. However, most existing schemes are based artificial objective rules or conventional models, which cannot desired effectiveness. Thus, we apply reinforcement lea...

Ad hoc wireless networks have become the architecture of choice for peer to peer communications in areas where the telecommunications infrastructure is inadequate or has failed. A major challenge is the reliable delivery of data when nodes move. The reliable Internet protocol is TCP. However, TCP performs poorly in mobile ad hoc networks, mainly because of route breakage. To overcome this probl...

Computer technology and its relative subjects developed at very high speed in recent years, so is geo-information science, including Geographic Information System (GIS), remote sensing (RS) and global position system (GPS). But with the increase of data, many data cannot be used efficiently because of the tremendous amount of data and information and the difficulty of process and transfer throu...

It is estimated that more than 80% of data that human beings have collected so far are geospatial data. In order for the geospatial data to be useful, information has to be extracted from the data and converted to knowledge. However, currently it is very difficult for general users to obtain geospatial data and turn them into useful information and knowledge. In order for geospatial information...

Abstract It is thought that the brain’s judicious reuse of previous computation underlies our ability to plan flexibly, but also inappropriate gives rise inflexibilities like habits and compulsion. Yet we lack a complete, realistic account either. Building on control engineering, here introduce model for decision making in brain reuses temporally abstracted map future events enable biologically...
