Indices

Here are the radiometric indices available for computing in Sen2Chain. Indices can me masked by any of the 4 cloudmasks.

\[NDVI = {{NIR-RED}\over{NIR+RED}}\]

\[NDWI(McFeeters) = {{GREEN-NIR}\over{GREEN+NIR}}\]

\[NDWI(Gao) = {{NIR-SWIR}\over{NIR+SWIR}}\]

\[MNDWI = {{GREEN-SWIR}\over{GREEN+SWIR}}\]

\[NDRE = {{NIR-RedEdge}\over{NIR+RedEdge}}\]

\[IRECI = {{NIR-R}\over{RE1/RE2}}\]

\[Brightness\,Index\,Blue\,Green = \sqrt{{BLUE^{2} + GREEN^{2}}\over{2}}\]

\[Brightness\,Index\,Red\,Near\,InfraRed = \sqrt{ {RED^{2} + NIR^{2}}\over{2} }\]

\[Brightness\,Index\,Green\,Red = \sqrt{ {GREEN^{2}+ RED^{2}}\over{2}}\]

\[Enhanced\,Vegetation\,Index = {2.5 * {( NIR - RED )}\over{( NIR + 6 * RED - 7.5 * BLUE ) + 1}}\]

\[Normalized\,Burn\,Ratio = {{NIR-SWIR}\over{NIR+SWIR}}\]

To compute, call for compute_indices() Tile’s method. Specify the indices and the Cloudmask version you want to mask them with, including the optional parameters of the cloudmask version (you can mask only with 1 specific cloudmask at a time)

Tile('40KCB').compute_indices(indices=['NDVI','BIBG','MNDWI'],cm_version='CM001', ...)
