How to know what particular imagery do you get from VANE Geospatial Platform

How to know what particular imagery do you get from VANE Geospatial Platform

The one of the ideas of VANE platform - no need of search by scenes and footprints. It is based on a simple assumption: each location in the world has metadata - click on any location and get information about all pixels containing this location. Such projects as cloudless atlases and Google base satellite maps are created according to this basic principle, stitching best imagery pixels in one seamless mosaic. According to scenes metadata VANE can preliminary compile the best satellite cover - users need to set up a parameter order=best for this operation. Even more, VANE language allows you to set up further requirements for your mosaic, providing appropriate parameters in your query - meaning: no older than (day>{yyyy-mm-dd})… or put all last imagery on the top (order=last)... or within the specific time interval (between({yyyy-mm-dd}:{yyyy-mm-dd}))…
Than you can go further, applying your custom colors to the result mosaic, according to VANE language specification.

Just to demonstrate this principle in work we’ve launched a very basic application called Finder.

Satellite imagery: Kīlauea volcano eruption, Hawaiian Islands

December 31, 2016 Kīlauea volcano erupted.
Kīlauea is a currently active shield volcano in the Hawaiian Islands, and the most active of the five volcanoes that together form the island of Hawaiʻi.
In Hawaiian mythology Kīlauea is the body of the deity Pele, goddess of fire, lightning, wind, and volcanoes. While the conflict between Pele and the rain god Kamapuaʻa was centered; Halemaʻumaʻu, "House of the ʻamaʻumaʻu fern", derives its name from the struggle between the two gods.

One of the most popular cases for weather API’s usage is the weather widgets.

OpenWeatherMap provides a bunch of weather API’s for developers, who create this kind of apps and many others. But our site is quite visited by users who’d like to check the weather for the certain city - so we created a various stuff of widgets you can copy and paste into your web page or blog as a ready-to-use JS code snippets no programming skills required.

Weather alerts from OpenWeatherMap

Weather alerts from OpenWeatherMap

We invite you to try our new product - the weather alerts which are based on our meteorological data.

Now you can use simple syntax and a few methods of the API to create triggers which will be working upon the occurrence of specified weather conditions (temperature, humidity, pressure, etc.) in a certain period of time. For example, if you are interested in the forecast of approach of frosts or probability of strengthening of wind in a certain place, then you can get this information by using our new tool. More detailed description of work with service is given below.

The alerts will be generated in our service after performing conditions of the trigger. It is necessary to poll service with a certain interval of time to receive it. In the future we are planning development of this direction, addition of push-notifications and new data sources.
