Hexagon Geospatial is committed to the success of our students and the future of geospatial technology. That is why we teamed up with the DigitalGlobe Foundation to provide licenses of our industry-leading software and high-accuracy, high-resolution satellite imagery to applicants with approved grants.
Nelchelle Anne de Guzman, a DigitalGlobe Foundation grant recipient and a Geodetic Engineering student at the Bicol University College of Engineering in the Philippines, conducted her research as part of our partnership with the DigitalGlobe Foundation. Nelchelle’s research examines aquaculture in Lake Buhi, a lake found in Buhi, Camarines Sur in the Philippines.
Aquaculture farming is one of the primary sources of food security and livelihood that gives alternative employment in the farming communities across the Philippines. It involves many kinds of water species that can be cultivated in the diverse ecosystem. The survey conducted by Nelchelle includes the accumulation of data on vulnerable farms and the effects on growth and development of the fishing industry within Lake Buhi.
To conduct the pre-processing and image classification analysis of aquaculture farms, ERDAS IMAGINE and other software were needed. The pre-processing operation also included the data from the Bureau of Fisheries and Aquatic Resources (BFAR), and the Philippine Statistics Authority (PSA), to acquire the list of Aquaculture farms in Lake Buhi, Camarines Sur.
High-resolution satellite imagery underwent pre-processing and image classification using remote sensing and GIS techniques. Geographic information systems, remote sensing, and mapping all play a role in the development and management of marine aquaculture. Maps help the community with decision making, which is very important in displaying data on boundaries, areas, and other environmental conditions and impacts. This is also an important tool for the local government agencies in aid of regulatory laws, and policies, in the ecological management of natural resources. The main goal of these spatial techniques is to fill the gaps of missing global statistical data.
Nelchelle’s results include processed multi-spectral and panchromatic satellite images showing samples shown in maps, inventory records and figures denoting the aquaculture farms in the year 2013 and 2015. Nelchelle found that remote sensing and GIS were useful in processing the imagery and creating the final map for her project. The object-based classification method was also effective in classifying the aquaculture farms in Lake Buhi. Nelchelle discovered that in 2013 and 2015, the number of aquaculture farms has decreased while the area of the lake has increased due to typhoons and soil erosion that also affected the productivity of the farms.
Thanks to Nelchelle for participating in our grant program and for her innovation with Hexagon Geospatial software. If you are interested in applying for a grant with the DigitalGlobe Foundation, visit our website for more information.
