| Abstract | Airborne image sensing systems are equipped on piloted or remotely-piloted aerial vehicles to collect imagery data. Often the equipped image sensors are mostly underutilized. The objective is to increase the sensor system utilization by enabling dynamic multitasking so that ground operators can access and transmit sensor task requests to an aerial vehicle. However, this may deviate the original route of an aerial vehicle. In this paper, we will be investigating this new problem of generating a new route to follow, as long as the assigned target points and original waypoints are not affected. Our goal is to find an optimal route on the fly between the given original waypoints such that it satisfies the maximum number of sensor task requests from ground users, of minimum sum of deviations subject to maximum deviation from the original route, without violating the original mission and flight maneuvering constraints. With the given constraints, finding an optimal route is an NP-hard problem. Therefore, we proposed two heuristic-based methods: namely, the FPCA approach that utilizes the idea of footprint diameter, and the SWCA approach that tackles this problem via the use of task clustering. The performance of these algorithms are compared through experiments using data from real flight trajectories. Our results show that SWCA outperforms FPCA in most settings. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
