Furthering Education through the DigitalGlobe Foundation

Hexagon Geospatial is committed to the success of our students and the future of geospatial technology. That is why we teamed with the DigitalGlobe Foundation to provide licenses of our industry-leading software and high-accuracy, high-resolution satellite imagery to applicants with approved grants.

Grant winner Michael Armand P. Canilao is a graduate student in the Department of Anthropology at the University of Illinois at Chicago and a research affiliate in the Archaeological Studies Program at the University of the Philippines Diliman.

Michael conducted his research as part of our partnership with the DigitalGlobe Foundation, using high-resolution satellite imagery from DigitalGlobe and Hexagon Geospatial software. His research examines the Lepanto Gold Network in Northwestern Luzon using remote sensing applications.

Michael prepared the high-resolution satellite imagery of the Lepanto Gold District using ERDAS IMAGINE’s pan-sharpening tool. Michael goes more in depth about his image enhancement techniques used in his research below:

Using ERDAS IMAGINE 2016 software, image enhancement was carried out on the WorldView-2 satellite imagery of the Lepanto Network including resolution merge using the Brovey transform technique. The image enhanced scenes were then analyzed using various band combinations but mainly focusing on WV2 mining operations (yellow-near infrared 1-red edge), and WV2 enhanced Infrared (near infrared 2-red edge-green). The mining combination allowed a detailed analysis of human occupation of the areas that fall within the suitable locations for bulking stations. The enhanced infrared combination allowed a synchronic snapshot into the environmental degradation within the immediate vicinity of the ancient gold bulking villages by comparing primary and secondary forests to grass lands.

We’d like to thank Michael for participating in our grant program and for innovating with Hexagon Geospatial software. If you are interested in applying for a grant with the DigitalGlobe Foundation visit our website for more information.
