SNOWVIEW AND FLOWVIEW - GEOGRAPHICAL PRESENTATION AND ANALYSIS OF INFORMATION IN BOTH TIME AND SPACE DOMAIN

摘要

The SnowView-project was initiated in order to develop a decision support tool for hydropower companies. The goal was to improve production control and flood warnings by better monitoring of the actual snow situation. The participants in the project wanted a PC-based, user-friendly system for snow analysis, based on remote sensing techniques combined with the users own measurements and historical information. The project gathered experienced people with background from remote sensing, hydrology, software development and project management. Unlike earlier applications the system does not require skills in the use of complicated image processing or "heavy" GIS-systems. Lessons learned and experience gained from the SnowView project has led to the development of the FlowView application. FlowView is tool that extends SnowView for unconstrained analysis of information in time and space domain. Time series and imagery can be used and combined. Aggregated knowledge and results can be presented and communicated to various user groups in an intuitive and understandable way. All is carried out in an easy to use geographical interface.
