Conference ‘Open GIS’17 Nov 2012

We make weather data to be available

to everyone.

OpenWeatherMap project is inspired by

Wikipedia and OpenStreetMap

ideas

We believe that enthusiasts joined by one idea could reach more results than large companies.

We believe that meteorological data must be available, free and easy-to-use.

OpenWeatherMap.org provides you with:

Weather in 120,000 cities

Data from 40,000 weather stations all over the world

20 different weather maps

1. Data collection: Weather stations

Professional stations

Private stationsOpenWeatherMap receives data

from professional and private weather stations

40,000 weather stations

1. Data collections: Weather stations in Russia and Europe

Density of weather stations.

Situation with weather stations in Russia looks dramatically in comparison with Europe.

1. Data collection: How to use data from weather station

After connection of the weather station it possible to build different types of charts using weather data from the station.

- Wind rose- Pressure- Weather forecast-Temperature variation … and many others.

2. Forecasts: Types• Global and Local forecasts • GFS CMC WRF models

Continent (middle accuracy)

Local (high accuracy)

Global (low accuracy)

We combine data from different forecasts with different scalability and accuracy

2. Forecasts: Enthusiasts make a local weather

WRF model is available as an

OpenSource software.

Budget of the system is$5,000

Blade server 16 core

The model works on PCs of enthusiasts.

We combine data from different modelsBy combining global and local models it possible to get global covering on the one hand and accurate detailed data for specific locations Base on these data we make interactive weather maps

2. Forecasts: How to use

3. Weather maps: Variety of types

Scientific applications (oceanology)

1. Mobile applications for iOS, Android, Windows Mobile2. Web-applications to display a current weather, charts, widgets and many others. 3. Smart house system, automatic garden irrigation system etc.4. Agriculture and scientific applications.

4. API: How to use

1. Current weather in city (more than 120,000 cities)2. Current weather in location – lat/lon3. Forecast for 7 days in a compact or full formats. 4. Data from weather stations 4. History
