Earlier this year, Intergraph® and DigitalGlobe launched a geospatial challenge for its users to exploit WorldView-2 imagery using the power and flexibility of ERDAS IMAGINE®. See the press release
ERDAS IMAGINE is the ideal tool for working with DigitalGlobe’s WorldView-2's rich set of spectral information, from an easy-to-use set of pre-defined band combinations for deciding on the best way to display the data, to the flexibility offered by the graphical Model Maker environment for designing and sharing new image analysis algorithms. ERDAS IMAGINE enables users to fully exploit and uncover all the information inherent in WorldView-2 imagery, including advanced image classification algorithms such as Spectral Angle, Spectral Correlation, Subpixel Classification and Object Oriented Image Analysis.
Out of the more than 100 research papers that were submitted for the Challenge, two winners were chosen: Priyanka Mehta and Allison Howard.
Mehta’s winning paper is Urban Temperature Profiling Using WorldView-2 8-Band Imagery and ERDAS IMAGINE. This project sought to classify urban land use and land cover to visualize temperature profiles and heat island effects as functions of urban development. The extra four bands of eight-band imagery from WorldView-2 provide increased opportunities for visualization and extraction of intricate features present in data.
Howard’s winning paper is A A Maximum Entropy and Least Cost Path Model of Bearded Capuchin Monkey Movement in Northeastern Brazil Incorporating ERDAS Subpixel Classification Analysis of WorldView-2 Imagery. Howard’s work has implications for predicting daily movement patterns of all mobile animals, as high-resolution imagery and subpixel analysis in conjunction with habitat modeling represent significant improvements to previous attempts to link species occurrence or animal behavior with environmental variables.
