Why Observe?: Land Cover

The video discusses the impact of the Biscuit Wildfire in Oregon and the role of satellite data in mapping and understanding land cover. It highlights the importance of citizen scientists and the GLOBE program in collecting data to fill gaps in satellite observations. The video explains land cover, its study through satellite imagery, and the significance of land cover observations in predicting environmental changes. It also covers urbanization's impact on flooding and the importance of community participation in scientific observations.
