VANE Platform gets Update with Planet Satellite Imagery Integration

We are happy to announce today that Openweathermap has partnered with Planet to provide access to current and archived Rapideye and PlanetScope satellite imagery in the VANE geospatial platform. Planet operates the world’s largest earth observation constellation of satellites and has the capacity to image the world’s landmass on a daily basis.

With this partnership, the VANE platform enables online processing and access to global high resolution imagery from Planet, further diversifying our Global Base Map product that currently offers publically available Sentinel and Landsat data.

World around us: NDVI vs NDWI

World around us: NDVI vs NDWI

This checkerboard picture is a satellite photo of Priest river in the northern Idaho.
It's interesting to see this area from the point of view of vegetation (NDVI) and water (NDWI) indexes.

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

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.

Beautiful maps: Deserts: Namib Desert

The Namib is a coastal desert in southern Africa. The name Namib is of Nama origin and means "vast place". According to the broadest definition, the Namib stretches for more than 2,000 kilometres along the Atlantic coasts of Angola, Namibia, and South Africa.

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.

These are maps, which you can compose by a combination of any three bands. For instance, use SWIR (band 7) instead of the red spectrum (band 4) and use NIR (band 5) instead of the green one (band 3), then you will get a map of land victimized by fire (See Fire detection, above).
 To get a map of a necessary color, just choose a combination of bands and you will find out what it looks like to see the world through eagle or wolf eyes.

Examples of VANE Language: Custom NDVI

The NDVI is a major vegetation index for the agricultural industry and farming, and with VANE Language you can customize a colour scheme to get a proper picture. Here in contrast to just the NDVI option a user can set a color scale and define the colors of zones. 

Examples of VANE Language: NDVI

Examples of VANE Language: NDVI

The NDVI, i.e. the normalized difference vegetation index, is a simple graphical indicator of biomass active photosynthetically.The NDVI is one of the most common and widely used indexes for evaluation of vegetated areas, their quality and quantity. Using the NDVI it is possible to detect presence of plants, its dynamics of emergence and growth. For getting of this index there is Band 5 which measures the near infrared spectrum, or NIR (Near Infrared). This part of the spectrum is reflected by water in leaves of healthy plants. Maps of the NDVI with dynamics (in various seasons) let tracing peculiar features and deviations of seasonal vegetation.

One of the simplest operations is to generate RGB map. Here an image consists of Bands 4-3-2 which correspond to the well-known RGB color model. Red, green and blue spectra combine together for creation of full color images.
