“8-band challenge”, fase 2

Digital Globe

Estados Unidos, 2011

In 2009, the company Digital Globe launched the WorldView2 satellite, the first high spatial resolution satellite providing 8 spectral bands in the visible and near-infrared (VIS-NIR) regions of the electromagnetic spectrum. In order to investigate the potential of the new sensor for different environmental applications, Digital Globe organized in 2010 and 2011 a research competition: the ‘8-Band Research Challenge’. They granted the best proposals free WorldView2 imagery and a final price to the best five applications. The authors of this report presented a research proposal, and later a paper, entitled “Object-based analysis of 8-bands Worldview2 imagery for assessing health condition of desert trees” to the 8-Band Research Challenge, Phase 2. A total of 350 researchers from 70 countries participated in this contest, and the paper of Chávez and Clevers from the Center for Geo-Information of Wageningen University was awarded as one of the five winner papers.
