Information Transfer and Cartographic Design Issues for Avalanche Risk Mapping

BACKGROUND The joint project “LWD Online Maps” between the Avalanche Warning Center Tyrol (Innsbruck, Austria) and the University of Vienna, Department of Geography and Regional Research is now ongoing for several years. Its goal has been and still is to develop and maintain a complex and very powerful database driven online decision support system for cartographic visualization and analysis of...

Extended Context Patterns - A Visual Language for Context-Aware Applications*

The paper presents a visual language that can help users of a context-aware application represent the current situation, or situations they wish detected, in a language that is both formally defined, and readable and understandable by humans and machines alike. Inspired from Regular Expressions, the concept of Extended Concept Pattern provides both conciseness and expressive power, allowing for...

Design and implementation of a WEBGIS-based recommendation system based on context-awareness for tourism planning

Today, tourism is one of the most lucrative industries in the world. Due to the large amount of information that exists about the points of Interest (POI) of a city, the tourist is faced with an overload of information. As a result, a recommending system is needed to recommend suitable tourist places to the tourist in the shortest time. In order to offer a better offer, the interests and contex...

Colour Extended Visual Cryptography based on MKGED

Visual Cryptography is a technique used to protect image based secrets. In this work, encryption method based on Modified Kernel based Gaussian Error Diffusion (MKGED) for colour extended visual cryptography, for visual quality improvement. This work depends on two important parameters and they are cluster centre points �� and pseudo covariance matrix ��. On analysis, it is found that the perfo...
