MNDWI is the normalized difference of Green Band and SWIR Band. In LANDSAT both are of a similar resolution i.e. 30m.
In the case of LANDSAT
var landsat8 = ee.Image("LANDSAT/LC08/C01/T1_RT_TOA/LC08_148044_20130425")
var ndwi = image.normalizedDifference(['B3', 'B6']).rename('MNDWI')
gives us MNDWI Band
whereas in the case of Sentinel 2 the resolutions of Green Band (B3 is 10m) and SWIR Band (B11 is 20m) are different.
How to change SWIR Band to more finer resolution so that I can apply normalized difference?
