The hydrographic survey described in this paper is part of the draft guide for revitalization and improvement of watercourses and flood forecast upgrading for the better defense…

The shallow water coastal environment characterises the critical interface between activities at sea and on land. Much of the economic activity at sea that is now being recognised as the Blue Economy takes place ‘out there’, away from our focus of attention on land. But all of it, at some stage…

Himachal Pradesh has been experiencing massive growth in hydel electricity projects during the last two decades or so. It was mainly on account of successive state government’s policy and emphasis on harnessing the hydel power potential of the state. As Himachal Pradesh…

Urbanisation is one of our most significant challenges (Suzuki et al, 2010). Rightly or wrongly, achieving sustainable urbanisation has been increasing reliant on high-rise, high-density buildings as the dominant urban form, and the stratified use of space to provide infrastructure, utilities and services both above and underground.

In the mid 1980s, cities around the world had experienced unparalleled changes in their economy, society and environment due to globlization, modernization and urbanization…

A protected area network like Kanha Tiger Reserve, in general, protects and manages a vast spectrum of wildlife. However, the conservation of charismatic large mammals and wildlife of high conservation value tends to overshadow all other wild animals and birds…

GNSS is a key technology of the communications, navigation, and surveillance (CNS) infrastructure, essential for the introduction of Performance Based Navigation (PBN) and Automatic Dependent Surveillance-Broadcast (ADS-B)…

The Normalized Difference Water Index (NDWI) is derived using similar principles to the Normalized Difference Vegetation Index (NDVI) to enhance the spectral reflectance of surface water bodies…

Valuation of real estate/ properties is in many countries/ cities the basis for fair taxation. The property value depends on many aspects, including the physical real world aspects (geometries, material of object as build) and legal/ virtual aspects (rights, restrictions, responsibilities, zoning/development plans applicable to the objects spaces). The aim of this study is to investigate the opportunities provided by the semantically rich 3D building and cadastral models for valuation and taxation. In this paper we investigate the following related aspects…

The most basic operation of a vessel monitoring system is to determine the location of the vessel at a given time, and periodically send this information, usually by satellite, to a monitoring station ashore. Most of vessels are tracked using the purple finder. This finder uses various satellites like Inmarsat, Globalstar and Thuraya for tracking the vessel. INMARSAT-C has been the most considered choice, since INMARSAT transceiver is already fitted onboard many ocean-going vessels as required by GMDSS (Global Maritime Distress and safety System).
