Global Base Map

VANE platform enables online processing and access to the global open and commercial satellite data. To learn how to build queries to define time period, select RGB bands combintation, apply formulas and custom colors, etc. - see VANE language documentation and examples.
Global Base Map combines different data depending on the zoom level - basically including open data from Modis, NPP, Sentinel-2 and Landsat-8 satellites. The default view of the map is provided in "True color" rendering and the imagery is automatically sorted in the best order, meaning - each tile is selected according to the best fit to the summary of the recentness, cloudiness and some extra characteristics.

True color - Go to Map

"True color" is a rendering of red, green and blue satellite imagery spectral bands to the RGB composite image that seems to look natural and applies specific color algorithms.

False color - Go to Map

"False color" is a rendering using NIR (near infrared) band which is more useful to visualize land cover and differentiate it from the urban area.

NDVI - Go to Map

"NDVI" is a processing formula that uses near-infrared and red spectral bands to calculate and monitor health vegetation growth and it's dynamics.
This index is mapped from a white to green hue, where green indicates good crop and white indicates very poor crop or an absence of vegetation. NDVI data is strongly important for agriculture and Farm management applications.

NDWI - Go to Map

The Normalized Difference Water Index (NDWI) is known to be strongly related to the plant water content. It is therefore a very good proxy for plant water stress.

Drought index - Go to Map

"Drought index" is another expamle of the indexed maps and is used to detect the presence of water and moisture on the ground. The calculated pixel values range from blue to brown, where blue indicates the presence of water and brown indicates dry land.
