Howto calculate Moisture Index in ArcGIS Pro using Landsat 8 satellite image

Moisture Index is a more sophisticated use of spectral bands. It is an index, which is a calculation that computes a ratio between different bands. In the case of the Moisture Index, the bands involved are 5 (NIR) and 6 (SWIR 1), and the formula is as follows: (Band5-Band6)/(Band5 Band6) If the NIR band value is higher than the SWIR 1 band value, the result of the formula will be a higher (positive) value, denoting a high moisture level. Otherwise, it will be a lower (negative) value, denoting a low moisture level. The Moisture Index is a great tool for monitoring drought levels and measuring desertification trends.
