The role of the distribution of inland water bodies with respect to the transmission of visceral leishmaniasis (VL) and its dominant vector, Phlebotomous argentipes, has been studied at the regional scale in Bihar, eastern India. The Landsat TM sensor multispectral scanning radiometer, with a spatial resolution of 30 m in the visible, reflective-infrared and shortwave-infrared (SWIR) bands, was...

This paper presents the Squirtle, an Autonomous Surface Vehicle (ASV) for autonomous navigation and capable of manoeuvring in tight river environments. Its main features include precise localization with RTKGPS and inertial sensors, high manoeuvrability and autonomy, depth sensing and obstacle detection. Its purpose is the exploration and mapping of the bottom of rivers and of their shores. The...

Water is the most vital resource for the living beings to survive. India has a vast and varied inland water resource which is considered to be richest in world’s nature lakes. The physicochemical characteristic of Nellore tank has been studied for monsoon, pre-monsoon, postmonsoon in the year. From the results water body was found to be well in the permissible limit of BIS (1998, except pH, DO,...

The altimeter emits a radar pulse, which is reflected at the nadir-surface and measures the two-way travel time, as well as the returned energy as a function of time, resulting in a return waveform. Over the open ocean the waveform shape corresponds to a theoretical model which can be used to infer information on range corrections, significant wave height or wind speed. However, the waveforms o...

Chlorophyll-a (chl-a) levels in lake water could indicate the presence of cyanobacteria, which can be a concern for public health due to their potential to produce toxins. Monitoring of chl-a has been an important practice in aquatic systems, especially in those used for human services, as they imply an increased risk of exposure. Remote sensing technology is being increasingly used to monitor ...
