6^th International Conference on GIS and Remote Sensing November 23-24, 2020 Barcelona, Spain

A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. It is a computer-based tool that analyzes stores, manipulates and visualizes geographic information, usually in a map. GIS can refer to a number of different technologies, processes, and methods. It is attached to many operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications, and business. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis and visualization. GIS can relate unrelated information by using location as the key index variable. Locations or extents in the Earth space–time may be recorded as dates/times of occurrence, and x, y, and z coordinates representing, longitude, latitude, and elevation, respectively. All Earth-based spatial–temporal location and extent references should be relatable to one another and ultimately to a "real" physical location or extent.

It is the process of using the maps delivered by geographic information systems (GIS) in World Wide Web. A web map on the World Wide Web is both served and consumed, thus web mapping is more than just web cartography, it is a service by which consumers may choose what the map will show. Web GIS emphasizes geodata processing aspects more involved with design aspects such as data acquisition and server software architecture such as data storage and algorithms, than it does the end-user reports themselves. The terms web GIS and web mapping remain somewhat synonymous. Web GIS uses web maps, and end users who are web mapping are gaining analytical capabilities. The term location-based services refers to web mapping consumer goods and services. Web mapping usually involves a web browser or other user agent capable of client-server interactions. Questions of quality, usability, social benefits, and legal constraints are driving its evolution. The advent of web mapping can be regarded as a major new trend in cartography. Web mapping has brought many geographical datasets, including free ones generated by Open Street Map and proprietary datasets owned by Navteq, Google, Waze, and others. A range of free software to generate maps has also been conceived and implemented alongside proprietary tools like ArcGIS. As a result, the barrier to entry for serving maps on the web has been lowered.

Seismology is the investigation of tremors and seismic waves. Seismic waves are the rushes of vitality brought about by the sudden breaking of shake inside the earth or a blast. They are the vitality that goes through the earth and is recorded on seismographs. GIS deals with the effect of Earthquakes and different calamities by evaluating danger and peril areas in connection to populaces, property, and normal assets, integrating information and empowering comprehension of the extent of a crisis to deal with an episode and recognizing arranging region areas, operational branches and divisions, and other vital occurrence administration needs. Geodesy is the art of precisely measuring and comprehension three principal properties of the earth its geometric shape, its introduction in space, and its gravity field and in addition the progressions of these properties with time. In connection to GIS, geodesy gives the crucial structure to exact positions on or close to the Earth's surface.

Present day GIS advances utilize computerized data, for which different digitized information creation strategies are utilized. The most well-known strategy for information creation is digitization, where a printed copy guide or overview plan is moved into an advanced medium using a PC helped outline (CAD) program, and geo-referencing capacities. With the wide accessibility of ortho-redressed symbolism (both from satellite and aeronautical sources), heads-up digitizing is turning into the principle road through which geographic information is removed. Heads-up digitizing includes the following of geographic information specifically on top of the elevated symbolism rather than by the conventional technique for following the geographic shape on a different digitizing tablet (heads-down digitizing).

Geostatistics is a branch of measurements concentrating on spatial or spatiotemporal datasets. Grown initially to foresee likelihood circulations of mineral evaluations for mining operations, it is as of now connected in different orders including petroleum topography, hydrogeology, hydrology, meteorology, oceanography, geochemistry, geometallurgy, geology, ranger service, natural control, scene biology, soil science, and farming. Geostatistics is connected in changed branches of geology, especially those including the study of disease transmission, the act of trade and military coordinations, and the advancement of productive spatial systems. Geostatistical calculations are fused in numerous spots, including geographic data frameworks (GIS) and the R factual environment.

Geodynamics is the investigation of movement and change on Earth. It gives the quantitative establishment to the hypothesis of Plate Tectonics, Volcanism, the science of magma and volcanic rocks, gravity and geomagnetic inconsistencies and in addition seismic examinations concerning the structure of the mantle. Geodynamics represents considerable authority in top of the line Geographic Information Systems, offering a wide range of GIS administrations from basic information transformation to complex hydrographical information handling, information demonstrating and examination. Plate motions and plate deformation.

Remote sensing in urban areas is a capable instrument to survey and analyze both how urban structures advance and how connected answers for urban issues are created. Examinations can include inside and out cross-correlations of urban communities crosswise over geographic ranges, across the nation or all inclusive. Every remote detecting "estimation" is a concise point in time and space that can have high worldly determination, and considers the obtaining of information that might be too expensive to gather in-situ. The information is additionally not obliged by political limits or ruined by varying accumulation techniques. Quantitative and additionally subjective examinations can be made for past, present, or future fleeting and spatial examples of urban advancement directions. By fusing social and financial information with remote detecting investigation, for example, general wellbeing, populace, modern information, or examples of defenselessness—issues of maintainability can be broke down and considered.

In natural resource management, remote sensing and GIS is mainly used in the mapping process. These technologies can be used to develop a variety of maps. Examples include: 1.Land cover maps 2. Vegetation maps 3. Soil maps 4. Geology maps. However, before these maps are developed, there are a variety of data that need to be collected and analyzed. Most of this data is collected with the help of remote sensing technology. Data can be collected using either ground photographs, aerial photographs or satellite photographs of the area of study. The choice of the photograph usually depends on the topography of the area of study and the aim of the study. For instance, aerial photographs (vertical or oblique) are always useful when spatial data need to be collected in the same area of study within intervals (hours, days, seasons, years etc.). This form of data collection shows the variations of the area of study within different periods of time. Satellite photographs can also be used to collect relevant data for the study. These types of photographs are however superior to aerial photographs in the sense that they have higher spectral, spatial, radiometric and temporal resolutions. Thus, satellite images are more detailed hence a lot of data can be generated from them. However, for remote sensing data to be effective, it needs to be incorporated together with topographical maps that show the variation of climate, soils, and other factors.

Geographic information systems (GISs) are becoming routine analysis and display tools for spatial data, used extensively in applications such as land-use mapping (for urban planning purposes), transportation mapping and analysis (for determining efficient transportation routes for deliveries and emergency response), geodemo graphic analysis (for facilities location), utilities infrastructure mapping (for precise gas, water, and electric line mapping), and multiple applications in natural resource assessment (including water quality assessment and wildlife habitat studies). GISs allow efficient and flexible storage, display, and exchange of certain kinds of spatial data, as well as potential interface opportunities for a variety of quantitative spatial analysis models. Users include: federal, state and local governments and their agencies, private firms, non-profit organizations, grassroots and community groups, universities, and research institutes. Yet, like all technologies, GIS co-evolves with the societies of which it is a part.

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

GIS maps are intuitive. On the computer screen, delineate can check a GIS outline any course, zoom in or out, and change the way of the data contained in the guide. From routinely performing business related assignments to logically investigating the complexities of our reality. GIS gives individuals the geographic favorable position to end up more profitable, more mindful and more responsive residents of planet Earth. Confronted with dreary forecasts of vitality supply and utilization, mankind is reacting with enormous endeavors to catch and develop renewable assets. We are hoping to support ourselves utilizing wind, sun based, geothermal, and biomass vitality. We are additionally looking for cleaner, more intelligent and more reliable strategies for vitality generation, transmission, and dispersion. GIS innovation is supporting and fundamental the advance of this momentous change. GIS is not just enhancing the way we create and convey vitality, it is changing the way we see our world's assets.
