WorldView-3, launched in 2014, is the first high spatial resolution commercial satellite with shortwave infrared (SWIR; 1,400-2,500 nm) imaging capacity. WorldView-3 therefore offers new opportunities for mapping wildfire burn intensity. We investigated optimal processing methods for mapping wildfire burn severity mapping using the high spatial resolution (originally 3.7 m, but degraded to 7.5 m due to licensing restrictions) and high spectral resolution (3 near infrared (NIR; 700 – 1,100 nm) and 7 SWIR bands) WorldView-3 data. The study site is in the Pinelands of New Jersey, USA, and focused on differenced (before – after) normalized difference burn ratio (dNDBR) imagery.
Dr. Timothy Andrew Warner is professor of Geology and Geography at the West Virginia University since 2005 and served as editor in chief of International Journal of Remote Sensing since 2014. He has a background in geology from University of Cape Town, South Africa (1979-1981) and finished his PhD in remote sensing in the Department of Earth and Atmospheric Sciences at Purdue University, Indiana (1987-1992). His research interests include the spatial properties of remotely sensed images, lidar, high spatial resolution imagery, thermal imagery, biogeographical applications of remote sensing (especially the study of the invasive species, Ailanthus altissima) and information literacy. From 2016 onwards he led the chair of Honors Committee in Remote Sensing Specialty Group (RSSG) of the American Association of Geographers (AAG). He is also member of the editorial advisory board of Progress in Physical Geography, editor of Remote Sensing Letters, editor of Geography Compass (GIS & Earth Observation section).
