Select the input data

Choose the multiband raster layer. Make sure that the input raster has the appropriate bands available.

Choose method to monitor vegetation

Select the method used to create the vegetation index layer. The different vegetation indexes can help highlight certain features, or help reduce various noise.

• Global Environmental Monitoring Index — The Global Environmental Monitoring Index (GEMI) is a non linear vegetation index for global environmental monitoring from satellite imagery. It is similar to NDVI, but it is less sensitive to atmospheric affects. It is affected by bare soil; therefore, it is not recommended for use in areas of sparse or moderately dense vegetation.
• Green Vegetation Index - Landsat TM — The Green Vegetation Index (GVI) was originally designed from Landsat MSS imagery, but has been modified for use with Landsat TM imagery. It is also known as the Landsat TM Tasseled Cap green vegetation index. This monitoring index can also be used with imagery whose bands share the same spectral characteristics.
• Modified Soil Adjusted Vegetation Index — The Modified Soil Adjusted Vegetation Index (MSAVI2) is a vegetation index that tries to minimize bare soil influences of the SAVI method.
• Normalized Difference Vegetation Index — The Normalized Difference Vegetation Index (NDVI) 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 near-infrared (NIR) band.
• Perpendicular Vegetation Index — The Perpendicular Vegetation Index (PVI) is similar to a difference vegetation index; however, it is sensitive to atmospheric variations. When using this method to compare different images, it should only be used on images that have been atmospherically corrected. This information can be provided by your data vendor.
• Soil-Adjusted Vegetation Index — The Soil-Adjusted Vegetation Index (SAVI) 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.
• Sultan's Formula — The Sultans Formula process takes a six-band 8-bit image and uses the Sultan's formula 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 and ETM bands of a Landsat 5 or 7 scene.
• Transformed Soil-Adjusted Vegetation Index — The Transformed Soil-Adjusted Vegetation Index (TSAVI) is a vegetation index that attempts to minimize soil brightness influences by assuming the soil line has an arbitrary slope and gradient.

Specify indexes of NIR band and RED band

Type the band indexes for the near-infrared (NIR) and Red bands.

Each satellite sensor and aerial camera capture information that is broken up into band indexes. Each band index contains the information for a specific part of the electromagnetic spectrum. This vegetation monitoring method requires the band index that captured the NIR and Red wavelengths.

Slope of soil line

The slope of the soil line. The slope is the approximate linear relationship between the NIR and red bands on a scatterplot.

This parameter is only valid for the Transformed Soil-Adjusted Vegetation Index.

Gradient of soil line

The gradient of the soil line.

This parameter is only valid for the Transformed Soil-Adjusted Vegetation Index.

Amount of green vegetation cover

The SAVI method requires the amount of vegetation cover to be specified.

Type in a value between 0.0 and 1.0, where

• 1 = areas with no green vegetation cover
• 0.5 = areas with moderate green vegetation cover
• 0 = areas with high green vegetation cover.

Adjustment factor

The Transformed Soil-Adjusted Vegetation Index method requires the adjustment factor set, in order to help minimize soil noise.

A value of 1 means that a regular SAVI index is performed. A larger value means that more soil noise is minimized.

Result layer name

This is the name of the layer that will be created in My Content and added to the map. The default name is based on the tool name and the input layer name. If the layer already exists, you will be asked to provide another name.

Using the Save result in drop-down box, you can specify the name of a folder in My Content where the result will be saved.
