dsi_oli: Landsat Surface Reflectance Derived Spectral Indices

In nightmares: Common Analysis with Remote Sensing Data

Description

This function requires Landsat Surface Reflectance from Landsat 8 Operational Land Imager to derive spectral indices.

Usage

dsi_oli(x)

Arguments

x	A raster layer object with the Top of atmosphere planetary reflectance with at least the first seven bands.

Value

Layer 1 - Normalized Difference Vegetation Index

Layer 2 - Enhanced Vegetation Index

Layer 3 - Soil Adjusted Vegetation Index

Layer 4 - Modified Soil Adjusted Vegetation Index

Layer 5 - Normalized Difference Moisture Index

Layer 6 - Normalized Burn Ratio

Layer 7 - Normalized Burn Ratio 2

Layer 8 - Advanced Vegetation Index

Layer 9 - Bare Soil Index
