We have built an extensive database for this project. It is comprised of three sets of forestry images - Pre-phase 01, Phase 01 and Phase 02. We extracted various features from these images, which are available at:

• USFS Feature Data: Feature data extracted from all three sets of images, both for SBE classification and automatic image segmentation

We have manually segmented the images into various regions to support research into image segmentation. See polygon regions for examples of how we segment images. Segmentation data is available at the following locations:

• Pre-Phase 01: Segmentation data for Pre-phase 01 images
• Phase 01: Segmentation data for Phase 01 images

In addition to the segmented data, we have also transcribed significant lines in the images to support edge detection research. See lines and edges for examples of how we identify lines in images. Line transcriptions are available at the following locations:

• Line Data: Significant lines for a part of Pre-phase 01 images
