About Weather
AGF 2013 3
What is Weather?
State of the atmosphere to the degree that is Hot or Cold, Wet or Dry, Calm or Stormy, Clear or Cloudy
Primarily driven by air pressure (temperature and moisture) differences between one place and another
One of the fundamental processes that shape the Earth The process of weathering breaks down the rocks and soils into smaller fragments
and then into their constituent substances. http://en.wikipedia.org/wiki/Weather

How is weather related to Geospatial Information?
Weather(without GIS) Weather + GIS
Raining
Raining in the city where I
live, so heavy traffic is
anticipated.

Typhoon moves
Typhoon moves up to
the area where my
parents live, so I should check
whether they’re safe or
not.

Sunny
Sunny at the beach, so
many people would come to the beach to enjoy the
sunshine.
Weather Chart
Weather meets maps, becoming weather chart(weather map).
AGF 2013 10
What is Weather Chart?
Weather Chart(aka Weather Map) is a snapshot of showing the principal meteorological elements at a given time and over an extended region based on a map.
Quite meaningful and Important to understand weather data at a certain time at a glance International rule for sharing timely and historical weather information
AGF 2013 11
Weather Chart on geographical locations
All weather data on Weather Chart are more meaningful when presented with geographical information.
Weather is highly dependent on geographical location because weather and geographical features closely interact.
Local weather is more sensitive to local residents, so geographical information is quite important to weather information.

Displaying Weather Data
Displaying Weather Data
Automatic display of basic analysis weather data from local or database after being gathered from weather stations, radars and satellite and processed on super computer.
Automatically displaying observation data and analysis data based on numerical weather prediction model
Automatically generating isoplethic curves, Isobars, Isothermal lines from grid data generated by various algorithms
Showing all necessary weather data for weather chart
AGF 2013 18
For the background map, Weather Note can communicate with any kinds of GIS engine which supports WMS protocol.
Possible to interactively change the base map even though map projections are altered.
