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.

Parameters

{select} bands that you choose for processing.
E.g., for RGB you set up b4,b3, and b2 bands, for NDVI -  b5,b4 

Examples of queries:

To get instantly the same image but with a different combination of layers just put a necessary combination in "Select" field and press "Show" button.
