Smart home. The relation of temperatures "inside" and "outside".

Smart home. The relation of temperatures "inside" and "outside".

From the first glance, ideal temperature is a subjective notion. It's a usual thing when some people open windows widely, while others wrap up themselves in sweaters and drink hot tea at one and the same room.
One badly tolerates heat, another is afraid of cold. When you are in a room, your comfort temperature depends not only on your physical peculiarities as of a human being, but also your comfort temperature is unique for every surroundings you are in.
The quality of isolation, the tasks you do at home, the amount of working equipment - there is a lot of factors which affect our perception of desired temperature. The comfort temperature is a balance between a wish to wrap up yourself in tons of clothes and a rush every 10 min to cold shower.

SSL for "free" and "startup" accounts!

We are glad to inform that starting from today SSL-protocol is available for all our APIs and for all accounts including "free" and "startup".

Intellectual management of buildings. Weather API

Intellectual management of buildings. Weather API

Intellectual management of buildings simultaneously solves 2 crucial tasks: it lets decrease  electric power cost and reduce CO2 emission and it all together has a positive effect on ecology.  
For the present moment there exist ready solutions which allow reasonable management of all the equipment: lighting, air conditioning, ventilation, heating, cooling, secure systems, etc.
Effective tools of monitoring observe functioning of a building in real-time mode: the tools calculate energy consumption, analyze current technical issues, trace surplus of CO2 and its emission.
The analysis of data received with the monitoring tools also implements management of processes taking place in buildings remotely. For getting actual information, one needs only to launch a browser.     

And here an easy access to a huge storage of data arrays is really necessary: data of different kinds comes constantly and is being processed in real-time mode. 
Our OpenWeatherMap team is happy to know that our development of weather APIs which are used as a part of global solutions in such projects throughout the world contributes to increasing of energy effectiveness and thus helps to improve ecological situation.   

Model of climatic parameters calculation for single fields

There is a source at where we suggest several simple examples of what you can create in your application with the help of our weather data.

The weather alerts on our meteorological data

The weather alerts are ones of the tools that we offer for agricultural monitoring of fields For your convenience we have designed an interface for our API where you can create triggers for a polygon of any shape. These triggers will work out in case of emergence of specified weather conditions (temperature, humidity, pressure, etc.) during a certain period of time.    

For example, there is a field where some plants are inclined to suffer from freezing, while other plants need measures to be taken in case of strong wind – and you can easily get this information with our tool. Just set specific trigger conditions and if they happen you will get a program warning.  

Open Dashboard for Agricultural Monitoring

Today we’d like to show you what you can do with our data. Open Dashboard for Agricultural Monitoring ( is a presentation of possible use of weather and satellite data in your agriculture applications. This is a service where everyone can find weather data and satellite imagery of their fields easily through our APIs. All you need to do is just to register, to draw a polygon and you get all the necessary stuff in an instant.        

Here you can evaluate a condition of fields from satellite imagery and get clear information for analysis of the dynamic changes taking place on these fields. Also this service provides weather data for any specified area: forecasts, historical data and notifications about critical weather situations for a stated period.

If you are interested in embedding this service in your application you can find further information here:

We are glad to introduce a new version of our satellite image processing platform VANE.

We are glad to introduce a new version of our satellite image processing platform VANE.
So, what’s new:
Now a request with an error or invalid values will return a response with the recommendations on how to fix it. Also the validation of values became stricter.
For example, the “select” parameter takes only a definite amount of bands. Parameters’ specifications themselves have gone through some changes

You can find the detailed description here

It’s easier to work with colors now by using default color schemes and palettes. A corresponding default color palette is automatically generated depending on an operation (the “op” parameter) and a current data source (the “from” parameter). And of course you can make your own color scheme.

We are happy to announce that one of our products - API for UV-index has got significant improvement

We are happy to announce that one of our products - API for UV-index has got significant improvement.    
- Now besides current and historical data, you can also get UVI forecasts for periods of 8 days.    
Syntax has got considerably easier,  it has become clearer and more unified like other APIs version 2.5.  
- There is a new feature to request data on any geographic coordinates without limits on accuracy.
Accuracy of UVI modeled data has been increased twice (the interpolation grid step decreased from 0.5 to 0.25 degrees).      
- Soon the support of search by city name, city id and zip-code will be available. 

You can find the instructions for the updated version here 

Please pay attention that during 2 weeks UV-index data will be in open access.  Further, access to this data will be available only for paid plans starting from Developer. For more information on our plans please visit

The previous version of API ( will be announced deprecated soon, and no support will be provided for this version.

Webinar: VANE Language API

Webinar: VANE Language API

Please, join our webinar on May 23

Our specialist will tell about VANE geospatial platform and VANE language API - the concept of which is to unite all operations with remote sensing data into consistent queries, allowing developers to work with the data similar to other SQL-fashioned APIs they are familiar with.

After the webinar program, you can write your questions and get our consultation how to apply VANE capabilities and remote sensing data to your project or business. We appreciate your participation and feedback!
