Queries for satellite images with VANE SQL v 0.2: Layers

Queries for satellite images with VANE SQL v 0.2: Layers

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.

Queries for satellite images with VANE SQL v 0.2: Tiles or polygons

Queries for satellite images with VANE SQL v 0.2: Tiles or polygons

Request an area of your interest by two ways that are tiles (XYZ) and polygons consisting of a number of geographical coordinates (lat/lon)

Parameters:

{z}/{x}/{y} query by a tile server. Z is the zoom level, and X and Y identify the tile.
{polygon} encoded GeoJSON string, contains pairs of coordinates describing all points of selected polygon.

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


Maps is a very visually intuitive way for analysing large-scale weather phenomena like cloudness, 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.

Use of satellite technology for decreasing risks in agriculture. NDVI index

Use of satellite technology for decreasing risks in agriculture. NDVI index

The exploration of outer space and launching of satellites started in the 1960s. Having some romantic flair in the beginning, the satellite story went on and nowadays satellites are launched often and almost everywhere around the globe and their number is going to grow in the future. Together with that, a new question arose, what to do with a bunch of new information received? A huge lot of information has been gained in the satellite era, but its practical appliance can be seen only in certain spheres of economics.

 One of the spheres where data received from satellites are used effectively is agriculture. There is a range of agricultural problems which can be solved with the help of these data. Satellites are classified into ones of high resolution, of medium and of small. Basically for agriculture satellites of medium resolution of 5-250m per pixel are used. What can be seen in such satellite images and what tasks can be done with the help of satellite data?

Meanwhile space dimension technologies highly evolve and artificial space satellites explore other planets for decades already, satellite technologies for observing the surface of our planet also become more complicated. With analysis of data received from satellites one can if not solve entirely then as minimum contribute to solving of global issues in many aspects of human life such as agriculture, logistics on ground surface and in open water, environmental pollution, etc.

Big Data and analytical systems. Weather and satellite data on air pollution for exact forecasts

In recent years, the situation with air pollution is becoming more alarming and attracted the attention of leading media and politicians at the highest level. This is especially true of large cities such as Beijing, Los Angeles, Mexico City, Tehran, Johannesburg and other densely populated settlements, which are under the influence of various risk factors, such as dense traffic, the presence of air polluting enterprises located poorly in terms of ecology, where pollution levels sometimes exceed all standards many times.

Impact of climate change on agriculture: problems and their solutions

Impact of climate change on agriculture: problems and their solutions

It is not news nowadays that the climate on earth is changing. And this change is not a long-term prospect, this is a process happening here and now. Consequences of it one can observe in this day and age. Climate change has a global impact on the human environment, nature, wildlife. And surely it also takes its strongest toll on economics. Agricultural sector turns to be the most vulnerable one to climate change. Many agricultural plants, on manufacture and market sale of which economics of some countries and large sectors of world trade are based, are extremely susceptible to weather changes; unexpected climate changes, not to mention here a process of global warming, can affect production of these plants in the most disastrous way. In its turn this process can directly influence the majority of population of export countries, where cultivation of these plants is basically the only source of income, and in some cases the main element of the food supply.

The role of agrosystems in air pollution: satellite technologies suggest a solution

The role of agrosystems in air pollution: satellite technologies suggest a solution

Recently the issue of environmental pollution and of its consequence such as global warming has been highly discussed at different levels from mass media to heads of governments. United Nations conference on climate change which took place in Dec, 2015 in Paris, France obliged countries that use hydrocarbon fuels to decrease emission of greenhouse gases to the atmosphere, and this fact correlates with world economics looking toward implementation of use of renewable fuels. However this process is unacceptable and almost impossible for many countries at the moment. It goes without saying for such countries as Saudi Arabia, Venezuela and India, and even in the USA this decision of the Paris climate summit found its opponents. The denial of vital questions of climate change and global warming is similar to practice of "burying the heads in the sand." These issues do exist and take their toll on world economy not in the best way.
