respect to weather maps, '…the Web has to offer something to almost
everyone, and a lot to someone with knowledge of, or interest in, weather
phenomena.' First, the main characteristics of the Web as a medium for
dissemination and use of weather maps and television are compared. It
seems that these media are tailored to different kinds of use. Main
differences are found in the products disseminated, in access, spatial
coverage and up-to-dateness. The Web offers maps, but also weather data,
online visualisation tools and downloadable software to produce maps.
chapter gives an impression of the variety of maps. Four categories
are distinguished. 'Weather maps in a narrow sense' are mainly based
on observations at weather stations. They show conditions of the atmosphere
in the immediate past or present, or forecast future conditions. 'Satellite
image maps' and 'radar image maps' usually display recent or current
conditions of the atmosphere, but sometimes also short term forecasts.
Their sources and appearances differ. The category 'other weather and
weather-related maps' refers to maps in archives, climatic maps and
maps of specific phenomena, like uv forecasts, hurricanes and the ozone
layer. For each category some background information and selected examples
are provided. The selection illustrates that North-America is best endowed
with weather information, while e.g. Africa is less well-provided. Many
of the static examples offer at least some interaction. Dynamic maps
are most common among satellite and radar image maps. Sophisticated
examples, like VRML scenes, are found in the last category.
ends with some expectations. They are related to ongoing technological,
professional and commercial developments. One such development is a
trend towards customised weather provision on mobile phones. Finally,
it is hoped that in the near future weather maps will be made accessible
to a broader audience.
