Unmanned aerial remote sensing: Sky is the limit
Bangladesh, March 23 -- Remote sensing has been around for more than a century. In the 1960s, space borne satellite imaging platform unveiled a new dimension to the application of remote sensing that served civilian purposes. Images sent by satellites offered valuable information about diverse issues starting from weather condition to deforestation to river erosion. Despite usefulness, low resolution and large time gaps of getting images of designated areas were among the major limiting factors. Although manned aerial vehicle-based imaging platform addressed these issues, due to the necessity of expensive aircraft and the airstrip to take off, it fell short of being an on-demand low-cost solution to fully exploit the potential of remote sen...
