Week 10 - Introduction to Arc GIS Pro and Multiband UAS Imagery
This week, we were introduced to ArcGIS Pro and worked with multiband UAS imagery to explore how different spectral bands and raster products can be used for analysis. Using a provided dataset, we examined individual bands, multiband composites, and vegetation indices to understand how surface features change across different map products.
We began by reviewing the dataset metadata and loading the imagery into ArcGIS Pro. Once the data was available, individual spectral bands were viewed to observe differences in reflectance across vegetation, roads, and burned areas.

Next, multiband composite rasters were explored. Both true-color and false-color composites were used to compare pre-burn and post-burn conditions. The swipe tool was used to visually compare changes between datasets.

Vegetation indices were then examined using NDVI layers. These maps highlighted differences between healthy vegetation and burned areas more clearly than single-band imagery.

Finally, a custom band combination was created by reassigning spectral bands to emphasize vegetation and surface features. This map helped highlight differences between fields, tree cover, and man-made features.

Overall, this lab provided hands-on experience using ArcGIS Pro to analyze multiband UAS imagery and demonstrated how different map products can reveal different information about the same area.
