2nd International Convention on Geosciences and Remote Sensing November 8-9, 2017 Las Vegas, Nevada, USA

Geology is the study of the Earth, including the materials that it is made of the chemical processes  and physical processes that occur on its surface and in its interior, and the history of the planet and its life forms. The study of changes in the planet and the life it harbours; over the course of time is an important part of geology. Structural Geology study the fracturing, folding, faulting and other forms of deformation experienced by rocks below the Earth's surface, and are also interested in how these processes relate to global Plate Tectonics. Petrology  study the origins and characteristics of igneous, metamorphic and sedimentary rocks. Petroleum Geology explore for and help produce petroleum and natural gas from sedimentary rocks.  Petroleum geology involves the extensive study of sedimentology and stratigraphy. Palaeontology study the remains of ancient animals and plants (fossils) in order to understand their behaviour’s, environmental circumstances, and evolutionary history. Environmental Geology study the environmental effects of pollution on ground and surface waters and surficial materials (sediment, rock and soil), and also solutions to environmental problems. They are also interested in understanding, mitigating and predicting the effects of natural hazards, such as erosion, flooding, landslides, volcanic eruptions, earthquakes, etc.

Palaeontology is the study of what fossils tell us about the ecologies of the past, about evolution, and about our place, as humans, in the world. Palaeontology incorporates knowledge from geology, biology, anthropology, ecology, archaeology, and even computer science to understand the processes that have led to the origination and eventual destruction of the different types of organisms since life arose. Micropaleontology is the Study of generally microscopic fossils, regardless of the group to which they belong. Taphonomy is the study of the processes of decay, preservation, and the formation of fossils in general. Paleoecology is study of the ecology and climate of the past, as revealed both by fossils and by other methods.  Many people think palaeontology is the study of fossils. In fact, palaeontology is much more.

Structural Geology is study of rock deformation. Study of how the lithosphere is bent , broken , and deformed during plate tectonics. Structural Geology is important for understanding the location of earthquakes, Formation of mountains and Tectonic history of the earth. The primary goal of structural geology is to uncover information about the history of deformation (strain) in the rocks using measurements of present day rock geometries, and ultimately, to understand the stress field that resulted in the observed strain and geometries. It is a main part of Engineering Geology, which is concerned with the mechanical and physical properties of natural rocks. A tectonic plate can be defined as a rigid rock mass of lithosphere floating over viscous and semi liquid and the less dense asthenosphere. The floating movement is defined as rate of movement of a tectonic plate. The plate boundaries can be of different types where the plates either diverge, converge or pass by each other. The process that takes place at plate boundaries is called the crustal deformation. The difference between structural geology and tectonics is that structural geology deals predominantly with the study of small scale deformation, from sub microscopic to regional. Tectonics deals with deformation on a global scale, for instance at the level of a whole region or a continent, or a whole plate.

Physical geology is the branch of geology that deals with the geologic events and materials occurring at the present time or in the very near past. This is in contrast to historical geology, which involves studying the rock record and fossil record for evidence of past geologic processes, life forms and materials. Physical geologists study current processes, like erosion, volcanoes, earthquakes, glaciers, and weathering. They use their understanding of historical geological processes to understand what might be causing current geologic processes to take place, as well as utilizing new techniques and technologies. Physical geologists share some similarities with medical doctors, in that they use a combination of prior knowledge and newly acquired technology and knowledge to help solve scientific problems. Physical geologists must also have a solid understanding of other branches of science, like physics, biology and chemistry, in order to fully understand the geological processes and interactions that are important to them.

Environmental Geology is investigates the relationship between society and the geologic environment. The three areas of study e three areas of study will be: will be: 1) geologic hazards such as floods, landslides, volcanoes and earthquakes; landslides, volcanoes and earthquakes; 2) geologic resources such as metals, stone, fossil fuels, and resources such as metals, stone, fossil fuels, and water; and, water; and 3) environmental challenges such as waste disposal and ground water contamination. The fundamentals concepts of environmental geology are Human population growth, Hazardous earth processes, Sustainability, Earth as a system etc. Research on environmental geology emphases on the chemical and physical processes occurring at or near Earth’s surface impacting by human activities. Hydrogeology is the important now a days as some parts of the world are blessed with frequent rainfall and plentiful surface water resources, but most of the countries need to use water that is stored underground to supplement their needs. Environmental geology applies geologic information to the prediction, solution and study of geologic problems such as Earth materials,  Landscape evaluation, Natural hazards, Environmental impact analysis and remediation.

Seismology is science that studies these waves and what they tell us about the structure of the Earth and the physics of earthquakes. It is the primary means by which scientists learn about the Earth’s deep interior, where direct observations are impossible, and has provided many of most important discoveries regarding nature of our planet. It is also directly concerned with understanding physical processes that cause earthquakes and seeking the ways to reduce their destructive impacts on the humanity. Seismology occupies an interesting position within the more general fields of Earth sciences and geophysics. It presents the fascinating theoretical problems involving analysis of elastic wave propagation in the complex media, but it can also be applied simply as a tool to examine the different areas of interest. Seismology is comparatively young science that has only been studied quantitatively for about 100 years. Reviews of history of seismology include Dewey and Byerly (1969) and Agnew (2002). Early thinking about the earthquakes was, as one might expect, superstitious and not very scientific. It was noted that the earthquakes and the volcanoes tended to go together, and explanations for the earthquakes involving the underground explosions were common. Paleoseismology is the geological investigation of individual earthquakes decades, centuries, or millennia after their occurrence.

Petrology is the study of rocks, minerals and meteorites, their occurrence, origin, composition, evolution, evolution of solar system and the interior of planets. Processes involve tectonic movements of masses, volcanic eruptions and injections, solidification and crystallization, recrystallization and melting, sedimentation, weathering, metamorphism, megascopic and microscopic identification of rocks and minerals. The interior structure of the Earth from the core, mantle, lithosphere, continental and oceanic crust, hydrosphere, atmosphere to biosphere illustrated along with nebular theory of origin and age. Rocks have been classified into the three major genetic classes, igneous, sedimentary and metamorphic. Theory of the plate tectonics for current configuration of Earth lithosphere and the component continents with zone of subduction, plate boundaries such as convergent, transform and divergent are discussed. Orogenic movements through the collision and non collision are explained.

Mineralogy is the subject of geology specializing in the scientific study of the crystal structure, chemistry, and physical (including optical) properties of minerals and the mineralized artifacts. Specific studies within the mineralogy include the processes of mineral origin and the formation, classification of the minerals, and their geographical distribution, as well as their utilization. 

Engineering geology is application of the geological knowledge in engineering works. It has wide applications in the various engineering fields especially in urban planning and expansion. Site investigation for major structures such as factories, dams, and the heavy buildings is one of the main parts of engineering applications. Others includes the earth material characterization, exploration and the assessment of construction materials and the assessment of difficult grounds such as sabkha, collapsible and expansive soils. The obtained information can be presented in the form of engineering geological maps, which is essential in several projects. Engineering geology studies are performed by a engineering geologist  or geologist that is educated, trained and has obtained experience related to the recognition and interpretation of the natural processes, the understanding of how these processes impact human made structures and knowledge of methods by which to mitigate against the hazards resulting from the adverse natural or human made conditions. The principal objective of the engineering geologist is the protection of life and the property against damage caused by the various geological conditions.

Oceanography is study of all aspects of the ocean. Oceanography covers a wide range of topics, from the marine life and ecosystems, to the currents and waves, to the movement of sediments, to seafloor geology. The study of the oceanography is interdisciplinary. The ocean’s properties and the processes function together and cannot be examined separately from one another. The chemical composition of the water, for example, influences what types of organisms live there. In turn, organisms provide sediments to geology of the seafloor. Oceanography’s diverse topics of study are generally categorized into four major sub disciplines. A sub discipline is the specialized field of study within a broader subject or discipline. Oceanographers specialize in the geological, biological, physical and chemical processes of the marine environment. 

Geophysics is the application of method of physics to the study of Earth. The rocks does not differ only by their microscopic or macroscopic properties studied field petrologists or geologists. They also differ by their physical and chemical properties. Hence as the rocks differ according to their origin, texture, structure, etc. they also differ by their magnetisation, density, resistivity, etc. However, modern geophysics organizations use a broader definition that includes water cycle including ice and snow; fluid dynamics of the oceans and atmosphere;  magnetism and electricity in the magnetosphere and ionosphere and the solar-terrestrial relations; and the analogous problems associated with  the Moon and the other planets. Geophysics is applied to societal needs, such as mitigation of natural hazards, mineral resources, and environmental protection. Geophysical survey data are used to analyse mineral deposits and potential petroleum reservoirs, locate groundwater, find archaeological relics, determine the thickness of the glaciers and soils, and assess sites for environmental remediation.

Geomechanics is the study of how soils and rocks deform, sometimes to fail-ure, in response to changes of stress, pressure, temperature and other envi-ronmental parameters. In the petroleum industry, geomechanics tends to focus on rocks, but the distinction becomes blurred because unconsolidated rocks can behave like soils.

Geomechanics is relatively young as a science and even younger in its application to the petroleum industry. However, it applies to nearly all aspects of petroleum extraction from exploration to production to abandonment and across all scales, from as small as the action of individual cutters on a poly-crystalline diamond compact (PDC) bit through drilling wells and perforating to as large as modeling fields and basins. Over the last 30 years, geomechanics has come to play an increasingly important role in drilling, completion and production operations. This trend continues as operators pursue oil and gas production from shales, in which mechanical anisotropy—the variation of mechanical properties with orientation—plays a vital role.

At the wellbore scale, geomechanics is central to understanding how drill bits remove rock, characterizing borehole stability, predicting the sta-bility of perforation tunnels and designing and monitoring hydraulic frac-turing stimulation programs. At the reservoir scale, geomechanics helps model fluid movement and predict how fluid removal or injection leads to changes in permeability, fluid pressure and in situ rock stresses that can have significant effects on reservoir performance. Engineers use geome-chanical modeling to predict and quantify these effects for life-of-reservoir decisions such as placing and completing new wells, enhancing and sustain-ing production, minimizing risk and making new investments.

Remote Sensing application is a software application that processes the remote sensing data. Remote sensing applications are similar to the graphics software, but they enable generating geographic information from satellite and the airborne sensor data. Remote sensing applications read specialized file formats that contain georeferencing information, sensor image data, and sensor metadata. Some of the most popular remote sensing file formats are NITF,  GeoTIFF, ECW (file format), JPEG 2000,MrSID, NetCDF, and HDF. Remote Sensing applications perform many features including Change Detection, Orthorectification, Spectral Analysis,Image Classification. Many remote sensing applications are built using the common remote sensing toolkits, like OSSIM and GDAL.

Remote sensing can be defined as the collection of the data about an object from a distance. Humans and many other types of animals accomplish this task with an aid of eyes or by the sense of smell or hearing. Geographers use technique of remote sensing to the monitor or measure phenomena found in Earth's, biosphere, hydrosphere, lithosphere and atmosphere. Remote sensing of environment by geographers is usually done with the help of the mechanical devices known as remote sensors. These gadgets have a greatly improved ability to receive and to record information about object without any physical contact. Often, these sensors are positioned away from the object of interest by using planes, helicopters, and satellites. Most sensing devices record information about an object by measuring an object's transmission of the electromagnetic energy from the reflecting and radiating surfaces. Remote sensing imagery has many applications in the mapping land use and cover, soils mapping, agriculture, city planning, forestry, military observation, archaeological investigations and geomorphological surveying, among the other uses. For example, foresters use aerial photographs for preparing the forest cover maps, locating possible access roads, and the measuring quantities of trees harvested. Specialized photography using colour infrared film has also been used to detect the disease and insect damage in the forest trees.

A Geographic Information System (or GIS) is a system designed to store, capture, manipulate, manage, analyse, and present geographical or  spatial data. The acronym GIS is sometimes used for the geographic information science (GIS) to refer to the academic discipline that studies the geographic information systems and it is a large domain within the broader academic discipline of geoinformatics. What goes beyond a GIS is spatial data infrastructure, a concept that has no such restrictive boundaries. In general, the term describes any information system that stores, integrates, analyses, edits, shares, and displays the geographic information. GIS applications are the tools that allow users to create interactive queries, edit data in maps, analyse spatial information, and present the results of all these operations. GIS science is the science underlying applications, geographic concepts, and systems.

                              GIS is a broad term that can refer to a number of different processes, technologies and methods. It is attached to many operations and has many applications related to planning, engineering, transport/logistics, management, telecommunications, insurance, and business. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on visualization and analysis.

The GPS is a Global Navigation Satellite System (GNSS) developed by United States Department of Defence. It is only fully functional GNSS in the world. It uses a constellation of between the 24 and 32 earth orbit satellites that transmit precise radio signals, which allow the GPS receivers to determine their current location, the velocity, and the time. These satellites are the high orbit, circulating at 14,000km/hr and 20,000km above the earth's surface. The signal being sent to earth at the speed of light is what is picked up by any GPS receiver that are now common place worldwide. The first satellite navigation system, used by United States Navy, was first successfully tested in 1960. Using a constellation of the five satellites. A GPS receiver calculates its position by the precisely timing the signals sent by GPS satellites high above the Earth. Each satellite continually transmits the messages containing the time the message was sent, precise orbital information, and the general system health, current date and time of all GPS satellites. The receiver measures the transit time of each message and computes the distance to the each satellite. A form of triangulation is used to combine these distances with the location of the satellites to determine receiver's location. The position is displayed, perhaps with a moving map display or longitude and latitude; elevation information may be included. Many GPS units are also show information such as direction and speed, calculated from the position changes.

Services which use the location co-ordinates of end-user to improve the relevance, context, and value of application are defined as location based services (LBS). As per Webster’s New World Telecom Dictionary, LBS are services offered by the cellular radio providers that are sensitive the physical location of terminal device. Such services include descriptions of and directions to restaurants and other retail establishments in the proximity. However, now the services may not only be offered by the carriers alone.

LBS and Mobile GIS are critical to many businesses as well as the government organizations to the drive real insight from data tied to a specific location where the activities take place. The spatial patterns that location-related data and services can provide is one on its most powerful and the useful aspect where location is a common denominator in all of these activities and that can be leveraged to the better understand patterns and relationships.

Geographic Information System software is designed to retrieve, store , display,  manage, and analyse all types of the geographical and spatial data. GIS software lets you produce maps and the other graphic displays of geographic information for analysis and the presentation. With these capabilities a GIS is a valuable tool to visualize spatial data or to build decision support systems for use in the multiple organizations. GIS stores data on the geographical features and their characteristics. The features are typically classified as lines, or areas, points, or as raster images. On a map city the data could be stored as points, road data could be stored as lines, and the boundaries could be stored as areas, while aerial photos or the scanned maps could be stored as raster images. GIS stores the information using the spatial indices that make it possible to identify the features located in any arbitrary region of a map.

Geographic information system and remote sensing are the extremely valuable and powerful instruments in debacle administration. Different debacles like avalanches, surges, seismic tremors, fires, torrents, volcanic ejections and violent winds are common dangers that murder bunches of the individuals and pulverize property and the frameworks consistently. Avalanches are the most consistent geographical vulnerabilities in mountain locales, especially in the Sikkim Himalaya. Remotely detected information can be utilised productively to evaluate seriousness and effect of the harm because of these calamities. In the debacle alleviation stage, GIS, assembled with the global positioning system (GPS) is to a great degree valuable in inquiry and the protect operations in the ranges that have been crushed and where it is hard to discover one's direction. Catastrophe mapping is drawing of territories that have been through the inordinate characteristic or man-made inconveniences to typical environment where there is lost life, property and the national frameworks.

The most vital segment of Geographic Information Systems is its prerequisite for spatial information. Spatial information is any sort of data that has been gathered, assembled, or prepared with a spatial segment, that is, an attach to a geographic area on the surface of the Earth. It so happens this is a vast fragment of the spatial business; regularly expending an obvious part of dollars doled out to GIS usage ventures. Spatial information administration is progressively a thought in any data administration framework (IMS) because of the way that a lot of information is being gathered with spatial parts. Organizations and government associations understand that a customary IMS does not permit an association to influence the estimation of spatial data characteristic in their information. This has prompted to the advancement of programming devices as expansions to business Data Management Systems (DMS) that take into consideration better stockpiling, control, and inquiry of spatial information.

A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, and other geologic processes. A natural disaster can cause loss of life or property damage, and typically leaves some economic damage in its wake, the severity of which depends on the affected population's resilience, or ability to recover and also on the infrastructure available.

A natural hazard is a natural phenomenon that might have a negative effect on people or the environment. Natural hazard events can be grouped into two broad categories. Geophysical hazards encompass geological and meteorological phenomena such as earthquakes, volcanic eruption, wildfire, cyclonic storms, flood, drought, and coastal erosion. Biological hazards can refer to a diverse array of disease and infestation.Many geophysical hazards are related; for example, submarine earthquakes can cause tsunamis, and hurricanes can lead to coastal flooding and erosion. Floods and wildfires can result from a combination of geological, hydrological, and climatic factors. It is possible that some natural hazards are intertemporally correlated as well

Drone technology allows GIS professionals to work more efficiently. With an easy-to-deploy mapping drone you can capture accurate aerial imagery and transform it into 2D orthomosaics (maps) and 3D models of small- and medium-sized sites – all on demand and without needing any piloting skills. As a new method of raster data collection, drone or UAV/UAS technology effectively complements existing techniques, fitting between large-area satellite/manned aircraft imagery and smaller coverage, time-consuming, but highly accurate terrestrial approaches
