Working With Multiband Imagery

For this post, we will be stacking raster bands to create a composite image. We will then work with a raster dataset to generate a composite image and develop a map product.

• First step is to access your data and open it in ArcPro
• I will be working with data collected at Purdue Wildlife Area (PWA)
• Metadata:
• Altitude: 120m
• Date of Flight: 06/14/2019
• Number of Bands: 5
• Band Names: Blue, Green, Red, Red Edge, NIR
• Pixel Size: 5.6cm
• Next we will generate a multiband composite raster:

1. Click on the analysis tab in the toolbar
2. Click the tools icon (red toolbox)
3. In the search area, type "Composite Bands"

    4.  Make sure that the bands are in correct order for false color IR from band 1 to 5

• A false color image is used to enhance features otherwise poorly visible to a human eye. A false color composite is a multispectral image interpretation using the standard visual RGB band range

The final step is to create our cartographic map. The proper requirements for this map include:

1. A false color IR of the orthomosaic composite
2. An RGB of the orthomosaic composite
3. A north arrow
4. A scale bar in meters 
5. A map title
6. A metadata section
7. A watermark that shows the map creator
