Population estimation with remote sensing

Timely small-area population estimates are critical for both public- and private-sector decision-making. Over the last decade, small-area population estimation has to a large extent benefited from the latest development of remote sensing. This study focuses on introducing methods for intercensal small-area population estimation from integrative use of airborne light detection and ranging, high-spatial-resolution satellite imagery, and nighttime satellite image. In particular, our study in Austin, Texas, provided an effective example for carrying out small-area population estimation with the integration of the state-of-the-art remote sensors.
