Satellite imagery: Landsat 8 and its Band Combinations.

Satellite imagery: Landsat 8 and its Band Combinations.

In the current version of VANE Language, we use images from Landsat8 satellite which captures the Earth’s entire surface every 16 days. The satellite makes hundreds of images with a unique name for each one like LC81410552016219LGN00 and a pixel size of 30 meters, each image consists of 11 bands, the size of the uncompressed image is 2 GB.
Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) images consist of nine spectral bands with a spatial resolution of 30 meters for Bands 1 to 7 and 9. New Band 1 (ultra-blue) is useful for coastal and aerosol studies, and also new Band 9 is applicable for cirrus cloud detection. The resolution of Band 8 (panchromatic) is 15 meters. Thermal Bands 10 and 11 provide more accurate surface temperatures and are collected at 100 meters. Approximate scene size is 170 km north-south by 183 km east-west (106 mi by 114 mi).
By default, we get B2, B3, B4, B5, B7, but it is possible to download any other bands

Set up the number and type of the layers that will construct your image to get grayscale image, RGB composed of 3 layers, or from combination of any other available layers.
In the current version of VANE Language, we use images from Landsat8 satellite. By default, we get B2, B3, B4, B5, B7, but it is possible to download any other bands. In the forthcoming version of the language, you can configure formulas like (b4-b3)/(b4+b3), NDVI(b4,b3) and many others.

Beautiful maps. Snows and Glaciers: Greenland.

The face of our planet is changing constantly. There are several reasons of this process, they are of natural and technogenic (i.e. a result of human activity) origin.
One of such processes that we can observe during the past decades is ice melting. And in particular, there is melting of big glaciers. This factor is a crucial one that impacts changing of the Earth’s surface the most. The matter is that this type of ice melting has the most influence on the level of the World Ocean, in comparison with melting of sea ice which is already in the water. Thus, observation of glacier melting has a great significance not only as a signal point in global warming, but also due to its impact on the level of a global ocean.

Weather maps: Rain modeling areas rendered by the VANE openweathermap platform

Maps is a very visually intuitive way for analyzing large-scale weather phenomena like cloudiness, pressure, rains, observing it in dynamic etc.
Maybe you’ve already tried to play out with our “Map Editor” tool - custom styled maps renderer that provides tile layers based on every 3 hr constantly updatable weather data sets.

Weather risk management on agricultural market through index-based insurance and weather data

Weather risk management on agricultural market through index-based insurance and weather data

In recent years, the problem of decreasing productivity of agriculture has arisen sharper due to climate change and long-term weather fluctuations; there is even the threat of famine in some countries, which are more dependable on crop productivity. This problem can be solved with traditional and known for centuries tools, i.e. by expansion of sowed land through deforestation.

Simultaneously, the intensification of manufacturing or the expansion of cultivated land into previously wild areas can lead to additional emission of greenhouse gases due to the removal of trees and also these processes can increase the amount of used fertilizers. These both actions are factors contributing to climate change and appearance of negative weather phenomena such as drought.
