Towards a web-based decision system for Philippine lakes with UAV imaging, water quality wireless network sensing and stakeholder participation

Abstract

There is a critical need for modern lake resource management in the Philippines because of climate change, disasters, intensive aquaculture and poor waste-management practices. To this end, we have deployed floating field-servers in Lake Palakpakin, one of the Seven Lakes in San Pablo City, Philippines monitoring conductivity, temperature, dissolved oxygen and turbidity at two depths-0.5 and 2.5 meters for over a year, with web access to data by SMS. We also have deployed UAVs to image the lake area to quantify fish cage density, water hyacinth coverage and disaster damage. The local fisher folk report daily lake activities-fish-feeding, harvesting, and fish-kill events by taking pictures and other measured data using smartphone applications. We describe how these measurements are being integrated into a web-based decision-support system.Keywords-decision-support system; water quality sensing; floating field server; UAV imaging; participatory sensing I.1 978-1-4799-8055-0/15/$31.00 ©2015 IEEE

Drones for Conservation in Protected Areas: Present and Future

“…Yet, the radiometric calibration of aerial images requires additional improvements [37] since it is considered a crucial step to carry out multi-temporal studies [236]. The confluence of big data [237], networked drones [238,239], artificial intelligence and sensors will bring new unforeseen perspectives to conservation, but integration of products and services to deliver off-the-shelf management solutions are still in their infancy.…”

A case study of an autonomous wireless sensor network system for environmental data collection

“…Unmanned aerial vehicles (UAVs) were widely used in military applications such as reconnaissance and surveillance [6][7][8]. With the cost reduction on rotorbased UAVs, more commercial applications have been explored such as shipping, traffic monitoring, and environmental sensing [9][10][11][12][13].…”

“…Different schemes have been proposed to provide energy and bandwidth-efficient designs for wireless sensor networks for data collection [11,[15][16][17][18]. Distributed Source Coding (DSC) with constrained Viterbi Algorithm (VA-DSC) with both convolutional and turbo codes which take advantage of known parity bits to increase the decoding performance while reducing decoding errors and computational complexity.…”

“…Solpico et al [11] have proposed improvements to a lake management and aquaculture productivity observation system. The system was designed to take measurements from floating field-servers, data from aerial imaging and data input from stakeholders.…”
