# Band Arithmetic function

## Overview

The Band Arithmetic function performs an arithmetic operation on the bands of a raster dataset. You can choose predefined algorithms, or you can enter your own single-line formula. The supported operators are -,+,/,*, and unary -.

## Notes

When using the User Defined method to define your band arithmetic algorithm, you can enter a single-line algebraic formula to create a single-band output. The supported operators are -,+,/,*, and unary -. To identify the bands, add B or b to the beginning of the band number. For example:

``````B1 + B2
b1 + (-b2)
(B1 + B2) / 2(B3 * B5)``````

When using the predefined indices, enter a space-delimited list indicating the band numbers to be used. The predefined indices are detailed below.

### BAI method

The Burn Area Index (BAI) uses the reflectance values in the red and NIR portion of the spectrum to identify the areas of the terrain affected by fire.

``BAI = 1/((0.1 -RED)^2 + (0.06 - NIR)^2)``
• NIR = pixel values from the near-infrared (NIR) band
• Red = pixel values from the red band

Using a space-delimited list, identify the red and NIR bands in the following order: Red NIR. For example, 3 4.

### EVI method

The Enhanced Vegetation Index (EVI) method is an optimized vegetation index that accounts for atmospheric influences and vegetation background signal. It's similar to NDVI but is less sensitive to background and atmospheric noise, and it does not become as saturated as NDVI when viewing areas with very dense green vegetation.

``EVI = 2.5*(NIR - Red) / (NIR + 6*Red - 7.5*Blue + 1)``
• NIR = pixel values from the near-infrared band

### GEMI method

The Global Environmental Monitoring Index (GEMI) method is a nonlinear vegetation index for global environmental monitoring from satellite imagery. It's similar to NDVI, but it's less sensitive to atmospheric effects. It is affected by bare soil; therefore, it's not recommended for use in areas of sparse or moderately dense vegetation.

``GEMI = eta*(1-0.25*eta)-((Red-0.125)/(1-Red))``

where,

``eta = (2*(NIR2-Red2)+1.5*NIR+0.5*Red)/(NIR+Red+0.5)``

### GVI (Landsat TM) method

The Green Vegetation Index (GVI) method was originally designed from Landsat MSS imagery and has been modified for Landsat TM imagery. It's also known as the Landsat TM Tasseled Cap green vegetation index. It can be used with imagery whose bands share the same spectral characteristics.

``GVI=-0.2848*Band1-0.2435*Band2-0.5436*Band3+0.7243*Band4+0.0840*Band5-1.1800*Band7``

Using a space-delimited list, you will identify the six Landsat TM bands, ordered one through five and six. For example, 1 2 3 4 5 6. If your input contains six bands in the order expected, you don't need to enter a value in the Band Indexes text box.

This index outputs values between -1 and 1.

### MNDWI method

The Modified Normalized Difference Water Index (MNDWI) uses green and SWIR bands for the enhancement of open water features. It also diminishes built-up area features that are often correlated with open water in other indices.

### NDVI method

The Normalized Difference Vegetation Index (NDVI) method is a standardized index allowing you to generate an image displaying greenness (relative biomass). This index takes advantage of the contrast of the characteristics of two bands from a multispectral raster dataset—the chlorophyll pigment absorptions in the red band and the high reflectivity of plant materials in the NIR band.

The documented and default NDVI equation is as follows:

``NDVI = ((NIR - Red)/(NIR + Red))``

### NDVIre method

The Red-Edge NDVI (NDVIre) method is a vegetation index for estimating vegetation health using the red-edge band. It is especially useful for estimating crop health in the mid to late stages of growth, when the chlorophyll concentration is relatively higher. Also, NDVIre can be used to map the within-field variability of nitrogen foliage to understand the fertilizer requirements of crops.

### SAVI method

The Soil-Adjusted Vegetation Index (SAVI) method is a vegetation index that attempts to minimize soil brightness influences using a soil-brightness correction factor. This is often used in arid regions where vegetative cover is low, and it outputs values between -1.0 and 1.0.

``SAVI = ((NIR - Red) / (NIR + Red + L)) x (1 + L)``
• NIR = pixel values from the near-infrared band
• Red = pixel values from the red band
• L = the soil brightness correction factor, which varies depending on the amount of green vegetative cover. In areas with no green vegetation cover, L=1; in areas of moderate green vegetative cover, L=0.5; and in areas with very high vegetation cover, L=0, which is equivalent to the NDVI method.

Using a space-delimited list, you will identify the NIR and red bands and enter the L value in the following order: NIR Red L. For example, 4 3 0.5.

### SR method

The Simple Ratio (SR) method is a common vegetation index for estimating the amount of vegetation. It is the ratio of light scattered in the NIR and absorbed in red bands, which reduces the effects of atmosphere and topography.

Values are high for vegetation with a large leaf area index, or high canopy closure, and low for soil, water, and nonvegetated features. The range of values is from 0 to approximately 30, where healthy vegetation generally falls between values of 2 to 8.

``SR = NIR / Red``
• NIR = pixel values from the near-infrared band
• Red = pixel values from the red band

### SRre method

The Red-Edge Simple Ratio (SRre) method is a vegetation index for estimating the amount of healthy and stressed vegetation. It is the ratio of light scattered in the NIR and red-edge bands, which reduces the effects of atmosphere and topography.

Values are high for vegetation with high canopy closure and healthy vegetation, lower for high canopy closure and stressed vegetation, and low for soil, water, and nonvegetated features. The range of values is from 0 to approximately 30, where healthy vegetation generally falls between values of 1 to 10.

``SRre = NIR / RedEdge``
• NIR = pixel values from the near-infrared band

### Sultan's Formula method

The Sultan's process takes a six-band 8-bit image and uses the Sultan's Formula method to produce a three-band 8-bit image. The resulting image highlights rock formations called ophiolites on coastlines. This formula was designed based on the TM or ETM bands of a Landsat 5 or 7 scene. The equations applied to create each output band are as follows:

``````Band 1 = (Band5 / Band7) x 100
Band 2 = (Band5 / Band1) x 100
Band 3 = (Band3 / Band4) x (Band5 / Band4) x 100``````

Using a space-delimited list, you will identify the indexes of the five bands required. For example, 1 3 4 5 6. If your input contains six bands in the order expected, you do not need to enter a value in the Band Indexes text box.

### Transformed SAVI method

The Transformed Soil Adjusted Vegetation Index (TSAVI) method is a vegetation index that minimizes soil brightness influences by assuming the soil line has an arbitrary slope and intercept.
