Here we present a method for in situ radiance calibration of the DMSP OLS using a ground based light source as an active target. We found that the wattage of light used by our active target strongly correlates with the signal measured by the DMSP OLS. This approach can be used to enhance our ability to make intertemporal and intersatellite comparisons of DMSP OLS imagery. We recommend exploring the possibility of establishing a permanent active target for the calibration of nocturnal imaging systems.<\/jats:p>","DOI":"10.3390\/rs61212708","type":"journal-article","created":{"date-parts":[[2014,12,17]],"date-time":"2014-12-17T10:19:28Z","timestamp":1418811568000},"page":"12708-12722","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Aladdin\u2019s Magic Lamp: Active Target Calibration of the DMSP OLS"],"prefix":"10.3390","volume":"6","author":[{"given":"Benjamin","family":"Tuttle","sequence":"first","affiliation":[{"name":"Department of Geography and the Environment, University of Denver, Boettcher West, Room 120, 2050 E.
