The integration of satellite image data with forest inventory plot data is a popular approach for mapping forest vegetation over large regions. Several methodological choices regarding spatial scale, mostly related to spatial resolution or grain, can profoundly influence forest maps developed from plot and imagery data. Yet often the consequences...
Prevention of wellbore CO₂ leakage is a critical component of any successful carbon capture, utilization, and storage program.
