Title: Digital aerial imagery (RGB and multispectral) from the 1991-BF3 wildfire boundary near Corrals Trailhead Boise Idaho USA-2022 DOI: 10.7923/nfw8-6v95 Description/Abstract: This data set includes raw RGB (red, green, blue) and multispectral (5-band) digital imagery and processed data products collected 2022-05-20 at the 1991-BF3 wildfire boundary (FireCode: ID4367211616519910731, Welty and Jeffries 2020) near Boise Idaho, approximately 0.25 miles up from the Corrals Trailhead off Bogus Basin Road. We used a DJI Mavic 2 Pro with Hasselblad 20MP sensor (RGB) with Map Pilot Pro software and DJI Phantom 4 Multispectral sensor (5 band) with DJI GS Pro software to capture imagery over the area of interest. The RGB (Red, Green, Blue) imagery was collected in a crossgrid pattern at 41m above ground level; the resulting imagery have a ground resolution of 1cm/pixel. The multispectral imagery was collected at 66m above ground level (no crossgrid pattern); the resulting imagery have a ground resolution of 3.5cm/pixel. The images were processed and the products were created in OpenDroneMap version 2.8.8. All products are georectified and in WGS84 UTM Zone 11 N. **Data Use**: *License*: [CC-BY 4.0](https://creativecommons.org/licenses/by/4.0/) *Recommended Citation*: Marie, V., Zaiats, A., Roser, A., Olsoy, P., Delparte, D., Wickersham, R., & Caughlin, T.
