What if combine meteorology and cartography?

What people talk about when they just meet? Of course, about the weather. We also like to talk about the weather, but even more we want to give everyone the most accurate and up-to-dated weather. We do not want you leaving home at the morning to take these extra staff just in case the weather will change. Leave them at home and take an umbrella just when it really is going to rain. And then there will be always a chance to talk about the weather.

= About OpenWeatherMap = OpenWeatherMap is a cartograhpic service that provide weather data in any world place. Forecasts and current weather are calculated on the basis of "raw" data and processed information from the meteorological stations, as well as based on global meteorological data centers and scientific laboratories. All information about weather including precipitation, clouds etc., are displayed as layers that you can turn on/off and combine to each other. Our data are not limited by list of large cities and regions. We use interactive maps and you can find the detailed weather data in any location. For some region we reach accuracy up to 2 km! All data that OpenWeatherMap provides is corresponds to Creative Commons By-Attribution Share-Alike 2.0 license.

 * Data are not depend on any cartographic service. We use OpenStreetMap that is very close to our spirit.
 * Data of current weather and forecasts are available for connection to any cartographic services through API.
 * The screen with selected region and weather layers can be saved for all next visits of the web site, and the link to the view can be sent to friends or colleagues. Settings can be changed at any time.

= To developers = API section stores information about weather layers connection into any cartographic services.

= To those who have weather stations = We invite all enthusiasts to join the OpenWeatherMap project. If you have a weather station you can connect it by API/Connect. You can use API/data_upload or choose a software compatible with the API. The more weather data sources will be connected to OpenWeatherMap the more precise weather data in any location we could provide. We will help to connect any weather station!

= Join the project = We will appreciate any ideas and help. The project is seeking for weather enthusiasts and specialists in meteorology!
