The National Institute of Technology of Karnataka is home to many students staffs and their families. It covers 250acres, with a population of 5,000-7500. There are estimated 20 miles of water infrastructure, 15 miles of sewer infrastructure, 25 sewer manholes, and 86 miles of electric transmission towers,500 inlets. The national institute of technology of Karnataka has invested heavily in an enterprise architecture but it also should be capable of addressing the spatial and asset management needs for all further development. Within this system, the inventory remains incomplete. In order to have a complete inventory, new inventory of water, sewer, and stormwater systems to be used within the Project leader GIS for asset management, modeling, and other functions.

Utility mapping for National Institute of Technology Karnataka.

Principal Investigator 

This work emphasizes the importance of first of its kind, location based services with possible integration and improvisation on diverse platforms which includes barcode geolocation, radio waves, Wi-Fi, and fingerprint based sensors. Mapping the utilities around a complex location brings precise and clear perspective of surroundings just at the touch of one’s fingertips. The present work lends a new edge to utility mapping by extending its implications to campus areas, government offices, and malls with complex infrastructure spanning across wide regions. The initial work was to identify the features and tagging them with the latitude and longitudes values which enables us to incorporate the features (i.e. equipment, infrastructure, facilities etc.) with respective locations in floor level maps and indoor maps. Creating such a comprehensive and well-integrated platform enables the administrative department to have a clear account of the operation state and availability of the infrastructure and maintain a proper database for the replacements of the appliances/instruments with location based services. Furthermore, the users would also have provision to rise complaints over the appliances/infrastructures like pipe valves and electric poles and other issues which gets notified in the server database with map based interface and lets the concerned department to get notified about the issues and subsequently initiate immediate actions depending upon the priority. Apart from this, the project would be equipped with WiFi based locations services for the employees by tracking mobile MAC address of the users with the help of different buffer ranges and signal strength at specific location. Tagging a barcode along these features enables the users to know more about the location and concerned person, for instance, in tourism industry the users can scan the barcode and know about the status or the facts of any monuments, access, travel rote and mode of commute etc.

In 1999, the Department of Drinking Water Supply (DDWS) was formed under Ministry of Rural Development, for focused attention on drinking water and sanitation. Later was renamed as Department of Drinking Water and Sanitation in 2010 and in 2011, it was conferred the Ministry status, keeping in view the extreme importance given to the sector by the United Progressive Alliance government. The Ministry of Drinking Water and Sanitation is the nodal department for the overall policy, planning, funding and coordination of programs for drinking water and sanitation in the country

The deposits along the coastline are well-disposed long continuous beaches throughout the coastline. The shorelines of these areas have been experiencing both accretion and erosion. The beaches have enriched with economic minerals such as ilmenite, garnet, and zircon. In the present study focused on Beach Placer mineral deposits along the beach profile represented three-dimensional perspectives views. Moreover, the studies of grain size, heavy minerals, and beach profile variation have led to evaluate the placer potentiality in this region. The integration of mapping and database through Arc GIS allows us to identify and analyze the possible correlation between the variables of heavy mineral placers in that location. Data of beach profile, grain size, and heavy mineral values are displayed in the form of polygon and buffer to show the relationship among them.

The coastal fresh water reservoir is a new emerging concept of storing floodwater in the sea close to the shoreline. The reservoir / Ponds may have an average depth of 10 to 20m with a maximum depth of 30 m. Sea based reservoir can be constructed in shallow waters at appropriate locations close to the mouth of the river along with a barrage at one or two ends. Sea walls or breakwaters with some modifications are good enough to construct the sea-based reservoirs. This concept envisages a sea-based reservoir stores fresh water, while the bottom of the reservoir is a mixture of sand and rubble. The emergent vegetation can cover about 20% of the surface area of these artificial reservoirs or ponds making it environmentally friendly. More species of fish call these ponds home! Many countries like China, Singapore, Hong Kong, The Netherlands, Japan, etc. have already constructed such reservoirs to augment water supply and for other purposes of drinking water, while some other parts of the country receive excessive rains resulting in floods. This geographical and time variance With the ever-increasing population, demand for water keeps on increasing day by day. An average rainfall in India is about 4,000 billion cubic meters. But most of India's rainfall comes over a 4-month period starting from June to September. India also experiences years of excess monsoons and floods, followed by below average or late monsoons with droughts. Despite abundant rains in July to September, some regions face shortage

The understanding of structure and tectonics in an area is important as it sheds light on the magmatism, metallogeny, groundwater, seismicity, geothermal and hydrothermal resources. The Precambrian-Archaean rocks of Southern Peninsular India exhibit polyphase metamorphism, multiple deformation, repetitive folding and fracturing. The highly fragmented and widely disseminated rock types show contrasting fold styles, multivariate linear and planar features. These linear and planar features have controlled localization of minerals, ore bodies, ultra basics and alteration products at several places. Narayanaswamy (1966), Grady (1971), Sugavanam et al. (1977), Katz (1978), Drury and Holt (1980), Ramasamy et al. (1987), Naga (1988), Ramasamy and Balaji (1995) and Ramasamy et al. (1999) have studied the regional tectonic analysis of southern Peninsular India. Among these geoscientists, Sugavanam et al. (1977) attributed five phases of deformation and Narayanasamy (1966), Ramadurai et al. (1975), Katz (1978), Naga (1988) and Ramasamy et al. (1999) advocated two phases of deformation responsible for the tectonic evolution of Precambrian fold belts of southern Peninsular India. The northern Tamil Nadu, which is a part of southern Peninsular India wherein tectonic studies and alteration mineral mapping were carried out at few places and hence, disseminated information's are available. Hence, the present study aims to map the hydrothermal mineral alteration zones coupled with the detailed structural and tectonic studies of the region using Landsat 8 (OLI/TIRS) satellite imagery and gravity data in Northwestern parts of Tamil Nadu region.

Surface and subsurface water from Space using microwave remote sensing The ability to monitor terrestrial subsurface and surface water bodies with sensors mounted on aircrafts and satellites has been known for decades. Early launches of satellites and the availability of aerial photography allowed investigation of the potential to support hydrological applications from as far as space. There have been notable studies on integrating data from these instruments with hydrological modeling since the late 1990s. There is now a consensus among space agencies to strengthen the support that satellites can offer. This trend has stimulated more research in this area, and significant progress has been achieved in recent years in fostering our understanding of the ways in which remote sensing can support and advance flood forecasting. With flood frequency likely to increase as a result of altered precipitation patterns triggered by climate change (Drogue et al., 2004), there is a growing demand for more data and, at the same time, improved flood forecasting. The aim is to develop more reliable flood forecasting systems over large scales that account for uncertainty in observations, modeling, and output. Over the last few decades, there have been major advances in the fields of remote sensing, particularly microwave remote sensing, and hydrological and hydraulic modeling. Joining both research fields with a stronger integration of remote sensing of flood information and soil moisture and hydrologic-hydraulic modeling has only emerged over the last decade as a result of significant advances in microwave remote sensing techniques and high performance computing encouraging a boost in modeling, with uncertainty.

While oceans have been studied for the past several years, the research towards it has been carried out in a slow tone as compared to other fields of earth science. The present satellite technologies have given us wider scope in ocean studies (Robinson, 2004). In the early stages of ocean studies, satellites could offer only narrow bands, whereas after the launch ofLandsat-8 with the specific OLI band (Mishra et al. 2014) the opportunity for ocean studies has increased drastically. The present work was initiated with theoretical and conceivable ideas of ocean studies. The Landsat-8 band 1- coastal/aerosol (0.433-0453µm) (Vanhellemont et al 2014) and band 9 circus (1.360-1.390µm) has given a great step forward for ocean studies like shoreline analysis, ocean color mapping (Hu 2009), suspended sediment mapping, sea surface temperature mapping and identification of potential fishing zone (Nayak et al 2009). In continuation with this, in the present work coasts of Ramanathapuram and Tirunelveli district of Tamilnadu were considered to illustrate upon promising aspects of Landsat-8 in ocean studies. The results clearly indicate that Landsat-8 holds enormous potential for real time analysis of ocean properties in future.

Integrated watershed management using remote sensing and GIS A watershed is a basin like landform which is delineated by the highpoints and ridgelines that descends to the lower elevations in turn it acts a collecting basin of the rainfall water leading to the formation of the streams and rivers. Intergraded watershed management is an approach where we consider all the aspects that has an impact over the watersheds and also the impact that it would cause to humans if we disturb the cycle of the watersheds for example if we start to disturb the course of the rivers the agricultural activities will get deeply affected in turn it will lead to urbanization of the region were we start to lose the fertility of the soil further it affects the ecology of the watersheds Role of remote sensing and GIS has been a part and parcel of understanding the geology and geography of a region. The advancement of the remote sensing has given a lead in each and every Conner in the field of geology and geography understanding the potentiality and viability of their applications will give a supportive hand even during the crucial stages of disasters on other hand it will also help us to plan the fore coming issues and problems especially in the field of hydrology it has greater potential in identifying the groundwater potential zones, groundwater recharge zones and in the field of watershed management further it has also reduced the need of manual work which is very hectic for humans coming to our studies it has given an accurate results in morphometric analysis like linear, relief, and aerial analysis
