Weather Map 2.0 and Relief Maps are products that allow developers to add weather and relief maps to their applications using simple URL requests. 

OpenWeather will help you easily and quickly move to our Weather API if you have been affected by the closure of the Weather Underground API.

Relief Maps allows you to get relief maps from around the world. Set the position of the sun in your parameters and you will receive precise illumination of the earth’s surface and its relief for the conditions you have set.

The OpenWeather team announces Weather Maps 2.0, where you can now work not only with current weather layers but also with historical and forecast maps!

Objectives

As farms mainly consist of crop fields, which can be hundreds of acres in size, much time and a great deal of resources are demanded of farmers in obtaining an accurate picture of the overall condition of these farms.

Drying out of plants or, conversely, an excess of moisture and a rise in the number of pests: these can all take their toll on the size and quality of the harvest and demand a rapid response. There are also such problems as the danger of overusing fertilisers, which poses a threat not only in terms of extra costs but also in that it is harmful to the environment and primarily to the health of farmers themselves.

To maximise harvests, constant monitoring is required throughout the season; and it is not easy finding the time to keep up with changes for each crop, not to mention monitoring the condition of every single acre. When deciding on long-term plans, a comparative analysis has to be carried out for both the usual course of the seasonal cycle and, in particular, any crises that have arisen.

To assess the current situation and to keep track of changes compared with preceding seasons and with the condition of neighbouring fields, accurate information on both the past and the present is needed as well as future forecasts that are as precise as possible.

Solutions

There are currently numerous services that help with managing farms for any acreage: checking boundaries and nutrient and moisture intake, monitoring the negative effects of weather conditions and diseases, and controlling pest numbers. And this can all be done without having to visit the fields, just by using a phone or tablet screen or a PC.

It is exactly to provide these services that OpenWeather offers a wide range of APIs for different weather and satellite data combined in the one product, the Agro API, with universal and simple syntax.

We invite anyone wishing to do so to try out our weather widget’s new geolocation and weather map functionality – https://openweathermap.org (please note that ‘https://’ is required in the URL), which can be targeted to your specific location.

We are happy to announce that one of our products – API for UV-index – has been significantly improved.

• Now, as well as current and historical data, you can also get UVI forecasts for periods of 8 days.
  
• The syntax has been made considerably easier: it has become clearer and more unified, like other API versions.
  
• There is a new feature to request data for any geographic coordinates without limits on accuracy.
  
• The accuracy level of the UVI modelled data has been doubled (the interpolation grid step has been reduced from 0.5 to 0.25 degrees).  
  
• Soon, searching by city/town name, city/town ID and postal/ZIP code will be available.

You can find the instructions for the updated version at http://openweathermap.org/api/uvi.

Access to the UV-index data will be available for all our plans. For more information on our plans, please visit http://openweathermap.org/price.

The previous version of the API (http://openweathermap.org/api/old-uvi) will soon be announced as deprecated, and no further support will then be provided for this version.

Do you want to receive weather data in your language? We have extended the list of supported languages for weather conditions.

Now the following languages are available in our API:

Arabic (ar); Czech (cz); Greek (el); Persian (Farsi) (fa); Galician (gl); Hungarian (hu); Japanese (ja); Korean (kr); Latvian (la); Lithuanian (lt); Macedonian (mk); Slovak (sk); Slovenian (sl); Vietnamese (vi).

We invite our users to test translations for weather conditions in different languages. We will be happy to extend our language support according to your wishes. If you have any questions or suggestions, please send them to https://openweathermap.desk.com/. The specification for all weather conditions is available here: http://openweathermap.org/weather-conditions.

We have added new versions of the rendering styles for the Weather Maps API.

To get the weather map layers in the new predefined styles, you need to add _new to the appropriate layer name, as follows:

http://tile.openweathermap.org/map/{layer}_new/{z}/{x}/{y}.png?appid={api_key}

For your convenience while working with our historical data, we have created the History Bulk section at OpenWeatherMap.com. There you can find a manual on extracting data for different time periods and cities/towns; there are also examples of data extraction in JSON and CSV file formats, and descriptions of weather parameters.
