WIIS - General Product Overview

1. Introduction

WIIS stands for Weather Image Information System. It is a software package for handling meteorological data like Meteosat images or weather radar images and offers the following features:

Collection of image data from multiple radars, weather satellite (e.g. Meteosat) receivers and other data sources including standardized input via BUFR encoded files and links to GTS (Global Telecommunication System).
Calculation of composite images from multiple individual images.
High-resolution real-time display of different image types (so called "products").
Two different graphical user interfaces: An easy to use button-menu with user-definable buttons and a standard text-menu for the experienced user.

2. Configuration

Figure 1: Network Configuration

WIIS is based on a client-server architecture (Figure 1) consisting of two main parts: A server-task receiving incoming data from the radar stations or Meteosat receivers via

and a client-task which can run on the same computer as the server-task (standalone configuration without network as shown in figure 2) or on a separate computer. Of course, in the latter case the two (or more) computers need to be connected by some computer network.

This architecture facilitates the installation of multiple display stations (e.g. for flight control centers) sharing the same data base.

The server-task archives the incoming images in files with configurable sizes, calculates composite images, maintains lists of available images and allows clients to retrieve the image lists and image data. Multiple clients (up to some hundred - depending on the hardware configuration) are allowed to connect to the server simultaneously.

The client-task receives the requested images from the server-task and is responsible for displaying them on the graphics-screen. The client's features include:

Display of online or offline (locally stored) images.
Zooming and scrolling of the images
Display of arbitrary user-definable overlays (like maps, grids or other background information)
Fast display of consecutive image series (animation loops) in order to reveal weather movement and dynamic behaviour
Archiving and retrieval or images
Online help
Powerful and user-friendly color setup with user-definable color-sets
