You'll apply this Iron Oxide ratio and determine whether it helps you better distinguish the changes in the Chuquicamata mine. The Iron Oxide band ratio uses spectral reflectance information from the red and blue portions of the electromagnetic spectrum because iron oxides or hydroxides have high reflectance at 0.63-0.69μm (Red band) and high absorption at 0.45-0.52μm (Blue band). The Iron Oxide ratio has been used to identify hydrothermal alteration minerals associated with copper mineralization (Pour & Hashim, 2014). Different band ratios are meant to highlight different types of features and phenomena. A band ratio (or index) combines different spectral bands through a mathematical formula. Next, you'll generate an Iron Oxide band ratio to visualize additional information.

The power of multidimensional rasters is that the band combination chosen was applied to all the slices in one go. In the Layer Properties window, click the Source tab.

In the Contents pane, right-click Chuquicamata_Landsat and choose Properties.

If you scroll to the right on the attribute table, you'll also see a field called Acquisition Date, which lists the date and time that the images were captured. The ProductName field lists Surface Reflectance as the type of imagery information. All of this work is done by raster functions behind the scenes. The mosaic dataset template accounts for this by grouping all the bands that belong to a same image together. This means that each image is made up of six spectral bands, and each band is actually a separate raster. Overviews are like raster pyramids for a mosaic dataset: they are reduced resolution overview images that are generated to improve the speed at which the mosaic is displayed.Īlthough there are only five primary images in the table, each image is multispectral. The five primary images are the actual Landsat imagery. There are five images with a category of Primary and four with a category of Overview. If you're using a different version of ArcGIS Pro, you may encounter different functionality and results. This tutorial was last tested on using ArcGIS Pro 3.1.
