+# Dataset Card for Dataset Name
+
+This dataset represents aerial imagery and road labels suitable for binary segmentation and road network extraction.
+
+## Dataset Details
+
+Contains aerial imagery from St. Louis County, MN and road masks generated using OpenStreetMap center line data.
+
+### Dataset Description
+
+The aerial imagery was obtained from the St. Louis County Aerial Imagery Program, managed by private contractors. This program provides high-resolution imagery specifically for St. Louis County, Minnesota, and is well-suited for detailed local analyses. The imagery, captured during optimal conditions for visibility, offers a resolution of 1 meter, providing a clear and accurate view of the county's urban and rural landscapes.
+
+The road centerlines used in this project were sourced from OpenStreetMap (OSM), a community-driven platform providing geospatial data from contributors worldwide. The OSM dataset for St. Louis County, Minnesota, includes detailed information on road geometries and attributes, making it an ideal choice for generating road masks for model training.
+
+Using the OSM data, we constructed road masks by buffering the centerlines with variable widths based on road classifications such as highways, local streets, and unpaved paths. These buffered geometries were then rasterized to match the resolution of the St. Louis County aerial imagery, creating pixel-based representations of roads. This process ensures that the resulting road masks align seamlessly with the aerial imagery, providing accurate labeled training data for the model.
