GIS technology can be used for scientific investigations, resource management, asset management, archaeology, environmental impact assessment, urban planning, cartography, criminology, geographic history, marketing, logistics, Prospectivity Mapping, and other purposes.
For example, GIS might allow emergency planners to easily calculate emergency response times in the event of a natural disaster, GIS might be used to find wetlands that need protection from pollution, or GIS can be used by a company to site a new business location to take advantage of a previously under-served market.
Uses of GIS range from indigenous people, communities, research institutions, environmental scientists, health organizations, land use planners, businesses, and government agencies at all levels.
Uses range from information storage; spatial pattern identification; visual presentation of spatial relationships; remote sensing - all sometimes made available through internet web interfaces, involving large numbers of users, data collectors, specialists and/or community participants.
One of the primary services provided by a GIS project is the geo-referencing of various data layers for mapping projection, involving the use of satellite image data for GIS mapping including:
Satellite Imagery and aerial photography have proven to be important tools in support of mineral exploration projects. They can be used in a variety of ways. Firstly they provide geologists and field crews the location of tracks, roads, fences and inhabited areas. This is important for mapping out potential access corridors for exploration areas and considering the environmental impact of large project. These images are also useful for mapping outcrops and regolith systematics and vegetation cover across exploration blocks and over regional areas.
Pipeline Corridor Mapping
Improve Safety and Security for Pipeline and Transmission Surveys: Satellite imagery and GIS data have significant potential to reduce a number of safety and security issues for pipeline corridor planning as well as supply managers with solutions through spatial representation of data for land, lease management, exploration, production, transmissions, environmental, financial and facilities management. This information is required to make decisions that will significantly impact the operator's ability to provide the services demanded by their customers.
Satellite imagery and GIS maximizes security programs which can enable local governments to better assess and understand how to develop programs to save lives, protect property and enhance the future economic stability of their communities. The current threats to a country range from incidents of terrorism and information attacks on critical infrastructure to the potential use of weapons of mass destruction and the spread of infectious diseases. Each one of these threats could cause massive casualties and disruption to a country.
Satellite Imaging Corporation (SIC) provides 3D airport mapping using high resolution stereo satellite imagery to support airport pre-planning and design, airport layout plans (ALPs), navigational mapping, and airport security and aviation safety operations.
3D Digital Surface Models (DSM's) and Digital Terrain Models (DTM's) can be created to support airport and aviation operations to provide details and data for the construction of airport runways, airport terminals, airport layout design, airspace analysis, obstruction surveys, facility mapping, taxiways, aprons/parking areas, 3D flight simulation for pilot training, aircraft operations, and GIS database development.
Land Cover Classification
Satellite imagery and GIS maps for land cover, land use and its changes is a key to many diverse applications such as environment, forestry, hydrology, agriculture and geology. Natural Resource Management, Planning and Monitoring programs depend on accurate information about the land cover in a region. Methods for monitoring vegetation change range from intensive field sampling with plot inventories to extensive analysis of remotely sensed data which has proven to be more cost effective for large regions, small site assessment and analysis.
Evaluation of the static attributes of land cover (types, amount, and arrangement) and the dynamic attributes (types and rates of change) on satellite image data may allow the types of change to be regionalized and the approximate sources of change to be identified or inferred.
Satellite imagery for urban and land development can be used to gather strategic planning information pertaining to a district or an entire city. High resolution satellite imagery and LiDAR incorporated into a GIS (Geographic Information Systems) and CAD (Computer Aided Drafting) has gained popularity among Planners, Developers and Engineers for large scale mapping of any region for most urban and land development applications.
Information from satellite images when combined with GIS mapping is used for analysis in evaluating construction costs as well as environmental impact of alternative routes for utility and transport corridors; land cover and land use classification; identifying population groups at risk where human intervention is most needed to limit and prevent hazards during development stages.
Pre and post 2D/3D seismic surveys
No matter how remote, Satellite Imaging Corporation (SIC) can retrieve satellite images from the most difficult-to-photograph areas of the world. For heavily forested areas, we provide medium-to-high resolution "Bare Earth" DEMs. This provides weather independency, allowing us to map large areas of terrain in limited timeframes, independent of the weather and solar illumination conditions. We are also familiar with specialized retrieval methods used for satellite imagery in remote areas, highly developed areas and areas of persistent heavy cloud cover such as the tropics.
Environmental Impact Studies (EIS)
Satellite Imaging Corporation (SIC) provides satellite image data at different spatial, spectral, and temporal resolutions by using the appropriate combination of bands to bring out the geographical and manmade features that are most pertinent to your project for detecting and monitoring environmental changes.
Satellite imagery and GIS have greatly expanded opportunities for data integration, analysis, modelling, and map production for environmental monitoring and assessment. As populations grow, as countries boost their economies, as landscapes change, governments have increasingly relied on up-to-date satellite imagery and other geospatial data for applications such as environmental planning, land registration, disaster response, public health, agricultural biodiversity conservation and forestry.
Coastal erosion studies
Many coastal managers are changing the way they manage coastal problems. Instead of only undertaking corrective measures, officials are moving toward prevention. Using potential models with satellite imaging technology and land cover data through GIS, managers can create scenarios for future development, as well as permitting and land use scenarios, to estimate the impacts on sensitive water bodies.
Satellite images can provide coastal management researchers and scientists with data for assessment and analysis of water temperature, salinity, phytoplankton, hydrology, shoreline changes, bathymetry, soil moisture and potential threats to our coasts.
Assessments and predictive capabilities through satellite imagery incorporated with GIS are needed to predict onset of events that may significantly affect human health, critical wetlands and ecosystems, and economic development.
Satellite images which forms the base for the generation of action plan maps, if used in the background of intelligent cadastral vector data, can improve the details of the thematic maps as well as action plan maps. It also helps in the monitoring of land cover changes that can be identified by detailed change detection processing procedures and implemented in the GIS cadastre mapping project.
Satellite imagery and GIS maps can give emergency and disaster response officials a wealth of information for assessment, analysis and monitoring of natural disasters such as hurricanes, tornadoes and cyclone damage from small to large regions around the globe.
Estimates of the particular land cover classes that may be inundated by a natural disaster can enable operators and planners to better assess their region's risk and vulnerability. This information will allow for prioritizing target mitigation and preparedness activities for their area.
The use of multispectral satellite imagery is therefore critical for the separation of constituent materials within an image and for the interpretation of images of damage for pre or post-disaster assessment. View Before and after example satellite images here.

Geography is the study of Earth’s features and patterns of their variations in spatial location and time. Many questions of agricultural production are geographic in nature as the production depends on the environment and prevailing socio economic conditions, both of which vary spatially and in time. Examples are questions related to natural resources management, precision agriculture, agro-ecological classification for land use planning, regional trends and patterns in technology adaptation, agricultural productivity and income, non-Pont source pollution from agricultural lands, etc. Answering these questions requires access to large volumes of multidimensional geographical (spatial) information of weather, soils, topography, water resources, socio economic status, etc. Further, answers to even apparently simple questions require that the data from several sources be integrated in a consistent form. Geographical Information Systems or GIS enable representation and integration of such spatial information.
Geographic information systems (GIS) (also known as Geospatial information systems) are Computer Software and hardware systems that enable users to capture, store, analyze and manage spatially referenced data. GISs have transformed the way spatial (geographic) data, relationships and patterns in the world are able to be interactively queried, processed, analyzed, mapped, modelled, visualized, and displayed for an increasingly large range of users, for a multitude of purposes.
In a general sense, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information. GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations. Geographic information science is the science underlying geographic concepts, applications, and systems.
It is a special case of information system where the database consists of observations on spatially distributed features, activities or events, which are definable in space as points, lines or area. A geographic information systems manipulates data about these points, lines and areas to retrieve data for ad hoc queries and analyses.
Whether siting a new business, finding the best soil for growing bananas, or figuring out the best route for an emergency vehicle, local problems also have a geographical component GIS will give you the power to create maps, integrate information, visualize scenarios, solve complicated problems, present powerful ideas, and develop effective solutions like never before. GIS is a tool used by individuals and organizations, schools, governments, and businesses seeking innovative ways to solve their problems.
Today, GIS is a multibillion-dollar industry employing hundreds of thousands of people worldwide. GIS is taught in schools, colleges, and universities throughout the world. Professionals in every field are increasingly aware of the advantages of thinking and working geographically.
- Geographic: 80% of government data collected is associated with some location in space.
- Information: attributes, or the characteristics (data), can be used to symbolize and provide further insight into a given location.
- System: a seamless operation linking the information to the geography – which requires hardware, networks, software, data, and operational procedures.
- Not just software!!!
- Not just for making maps!!!
GIS can be used as synonymous to:
- GI Systems: A computerized tool that helps solve geographic problems.
- GI Science: The development of data models, algorithms, and methods for representing geography and spatial relationships in order to support spatial analysis and location-based computing
- GI Studies: The systematic study of society’s use of geographic information, including institutional, organizational and procedural issues.
- GI Services: The business of providing GIS data and analysis tools to GIS users (often by chaining interoperable components in logo-block fashion).

- When Gangnam Style surpassed 2.15 billion views on YouTube, the View Counter went negative, causing YouTube to release a statement saying "We never thought a video would be watched in numbers greater than a 32-bit integer (=2,147,483,647 views), but that was before we met PSY.
- The reason why we hate the recorded sound of our voice is because our skull changes the resonance of our voice from within and creates more bass. When we hear a digital recording of our voice, although slightly unfamiliar to ourselves, it's exactly how other people hear it.
- Due to increased brain activity, people with higher intelligence tend to have a harder time falling asleep at night.
- Chocolate can help fight against bacteria in the mouth and stop dental decay. Surprisingly, it can be good for your teeth.
- When Katherine Johnson was little, she loved to count things. By the age of 10, she was in high school. In 1961, she calculated the trajectory of NASA's first trip into space/ She was so consistently accurate that when NASA began to use computers, they had her check the calculations to make sure they were correct.
- A cat named Simon served on a Royal Navy ship in 1949, and received a medal for raising morale, killing off a rat infestation and surviving cannon shells during his service. Hundreds attended his funeral when he died from infected wounds.

What is coding? Why to code? How to code? Which language is easy to code? Which language is best to code? These are some questions that will come at least once across the student's mind. In simple way, we can say that coding is simply writing code in any programming language to solve some problem. Without any problem, there is no meaning of writing code. Actually, in the coding universe, there is always at least a problem to solve that the programmer solve using his/her logic in programming language. Coding is syntax specific. That is, every programming language has it's own syntax that we should follow while writing code. Also, we should choose language to code according to the nature of problem.
Here, in this post, I am going to present some ten reasons to teach coding to students.
- Coding allows students to create content, not just consume it.
- Coding empowers students and gives them tools to express themselves in really cool ways.
- Coding teaches story telling with games and animations.
- Coding is a place for students to take risks and fail safely.
- Coding is inclusive and builds self-confidence.
- Coding supports many principles of mathematics.
- Coding teaches problem-solving and critical / analytical thinking skills.
- Coding is a new type of literacy and will be a large part of future jobs.
- Coding develops teamwork and collaborative skills.
- Coding can help humanity by building human helping devices / machines.
