| MLSWI27 Algorithm Specification | |
The MLSWI27 operator algorithm computes the
Modified Land Surface
Water Index (MODIS Bands
2 and 7) from a given product.
The MLSWI27 results from the following equation:
MLSWI27 = (1.0 - N - S2) / (1.0 - N + S2)
, where:
The bands are:
- N is the NIR band
- S2 is the SWIR 2 band
Also the processor computes an additional flags band called 'mlswi27_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for MLSWI27 is NAN or is Infinite |
| Bit 1 | The computed value for MLSWI27 is less than -1 (minus one) |
| Bit 2 | The computed value for MLSWI27 is greater than 1 (one) |
