One of the benefits of the VANE platform is that there is no need to search by scenes and footprints. It is based on a simple assumption: each location in the world has metadata – click on any location and you can 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 the best imagery pixels in one seamless mosaic. Based on the scene’s metadata, VANE can choose the best satellite cover – you need to set up a parameter “order=best” for this operation.
As well as this, the VANE language allows you to set up further requirements for your mosaic, providing appropriate parameters in your query:
no older than (“day>{yyyy-mm-dd}”)
or put all the latest imagery on the top (“order=last”)
or within a specific time interval (“between({yyyy-mm-dd}:{yyyy-mm-dd})”).
Then you can go further, applying your custom colours to the result mosaic, according to the VANE language specification.
Just to demonstrate this principle at work, we’ve launched a very basic application called Finder.
