ee-tasseledcap: Calculates tasseled cap brightness, wetness, and greenness...

In r-earthengine/rgeeExtra: Extensions for 'rgee'

Calculates tasseled cap brightness, wetness, and greenness components for an EE Image or EE ImageCollection

Description

Tasseled cap transformations are applied using coefficients published for these supported platforms:

• 1. Sentinel-2 MSI Level 1C (1)

• 2. Landsat 9 OLI-2 SR (2)

• 3. Landsat 9 OLI-2 TOA (2)

• 4. Landsat 8 OLI SR (2)

• 5. Landsat 8 OLI TOA (2)

• 6. Landsat 7 ETM+ TOA (3)

• 7. Landsat 5 TM Raw DN (4)

• 8. Landsat 4 TM Raw DN (5)

• 9. Landsat 4 TM Surface Reflectance (6)

• 10. MODIS NBAR (7)

Usage

`ee$Image$Extra_tasseledCap(x)`

Arguments

x	ee$Image to calculate tasseled cap components for. Must belong to a supported platform.
