visIvis® as a High-Resolution Tool for Visibility Estimation

The European key player “Deutscher Wetterdienst” (DWD) has just acquired first licenses of visIvis®, Vision-Based Visibility Estimation

DWD as the German weather authority provides reliable visibility information, as a “just-in-time” service for air traffic management, road traffic and critical infrastructure. Fog in particular poses a safety threat here and can cause significant delays.

Based on images from any observation camera, the software suite visIvis®, developed by JOANNEUM RESEARCH and distributed by MeteoSolutions, calculates millions of visibility estimates from a single image, essentially one for each pixel.

In a project cooperation, Deutscher Wetterdienst (DWD) conducted a number of tests to compare some measuring instruments and observing methods for meteorological visibility. The results have shown that visIvis® is an ideal complement to localised measurements from transmissometers and a good alternative for human observers. visIvis® provides a complete overview of the observed area, so that very local weather phenomena are still detected quickly and reliably.
