VANE Platform News: timeline function

VANE Platform News: timeline function

• To make searching for images easier, a timeline function has been added. This means that images for a period in question, specific dates, or as near as possible to them, can be quickly found and examined. Cloud cover metadata allows you to evaluate beforehand how useful the photos are and to choose the most appropriate ones. This function is available for images from Landsat-8 (l8), Sentinel(se) and RapidEye (re).

• Added to the contour drawing mode is the capacity to create several polygons there and then and enter the coordinates textually (geojson).

The Polygon tool

The Polygon tool

An example of one of the services for agricultural applications offered by VANE has now been added to the Query Builder interface.

The Polygon tool allows you to isolate any outline you want in the photograph, process the satellite images in RGB and EVI, and arrange any color palette with any scale for a specific area.
It is possible to edit it, obtain data on the depicted polygon and download it from the geojson file.

 Then you can get the URL with the assembled polygon and copy it to your site

- the filter algorithm for selecting BEST coverage tiles has changed.
BEST - is the method for overlaying images (parameter value order), and is the best way possible, depending on the parameters selected: date range, satellite, percentage of cloud cover.
Changes to the algorithm have enabled the quality of coverage to be significantly enhanced:

Sentinel-2 - before

Sentinel-2 - after

- combined data sources Landsat 8 and  Landsat-8_TOA


Landsat-8

Landsat-8 + Landsat-8_TOA

Cloudless: global cloudless composite coverage based on the VANE Platform

Cloudless: global cloudless composite coverage based on the VANE Platform

In the drawing is global coverage obtained between 06.01.2017 and 09.01.2017 using data from the MODIS spectroradiometer aboard KA Terra and Aqua.

The current cloudless coverage of the Earth by medium and low-resolution satellite images are an important element in the regional and global systems that monitor the territorial changes caused by natural and man-made factors. For example, assessing the damage inflicted by forest fires caused by deforestation, volcanic eruptions, flooding,etc. Also, such types of coverage are popular as the base layer for cartographic web services.

The main stages of creating such coverage are: the selection of images, expert as a rule, the masking of clouded areas, tonal adjustment of images taken at different times of the year, and pasting them into single coverage using so-called “cutlines” which enable, to a certain extent, the joins between the pasted images to be hidden. Such operations, as a rule, are carried out in semi-automatic mode and require specialized software and highly qualified experts, which substantially increases both the time taken to create such a product and its cost.

You are invited to test the new web interface Query Builder for our Vane platform.
You can use this simple tool to create your own map in just a few minutes, and with just one click receive a completed link for display on your site or app using a web map library like Leaflet, Open Layer, Mapbox and Google Map.

This version is an improvement over the previous one in terms of simplicity of use and layout. The user can select either one of the available data sources and the required combination of spectral bands or one of the derivative index products such as NDVI, EVI, etc. You can also set up display parameters, including clarity, contrast and gamma correction, or use one of the available schemes provided. After that, all you need is to get an API key and insert it in the prepared link, and you can use it in your programming product.
We are ready to answer your questions and will be glad to hear any proposals you might have.

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 http://owm.io/vaneLanguage

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.

VANE Platform gets Update with Planet Satellite Imagery Integration

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.

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.
