      Careers in GIS and Remote Sensing

      Careers in GIS and Remote Sensing

      Today every area ranging from missile and unmanned aerial vehicle technology to urban administration, e-governance, remote sensing, energy sector, and even advertising and marketing depend on geospatial data. GIS and Remote Sensing are two exciting areas of technology to work on. But, what exactly are GIS and remote sensing? How do they work? WhatHow are the career scopes in GIS and remote sensing? In this article, we will address those questions.

       

      A geographic information system (GIS) is a framework for gathering, managing, and analyzing data. Rooted in the science of geography, GIS integrates many types of data. It analyzes spatial location and organizes layers of information into visualizations using maps and 3D scenes.

       

      Every day, millions of decisions are being powered by Geographic Information Systems (GIS). From pinpointing new store locations… to predicting climate change… to reporting power outages… to analyzing crime patterns.

      Introduction to Geographic Information System (GIS)

       

      Geographic information system (GIS) is a special system which is designed to capture, store, manipulate, analyze, manage, and present all types of geographical data on earth. GIS technology is an integrated database which has all the information like population characteristics, economic development opportunities, and vegetation types, maps etc. GIS allows to link the databases and maps and create dynamic displays. It also provides tools to visualize, query, and overlay the databases which are technically not possible through spreadsheets.

       

       

      Introduction to Remote Sensing

       

      While GIS helps in explaining and predicting the events on earth, remote sensing is an art and science of measuring the earth with the help of sensors. Remote sensors generally collect the data by detecting the energy that is reflected back from Earth. These sensors are arranged on airplanes and satellites. Remote sensors collect the data in the form of images and manipulate them for analyzing and visualizing the data. GIS and Remote sensors are interrelated as these remote sensors are integrated within GIS systems to visualize and interpret the collected data.

       

      GIS vs Remote Sensing

       

      A geographic information system (GIS) is a computer-based tool for mapping and analyzing features and events on earth. On the other hand, remote sensing is the science of collecting data regarding an object or a phenomenon without any physical contact with the object.

      You could also say that remote sensing is a specialized domain within the broad field of GIS. Read more on differences between GIS and remote sensing.

       

      How do GIS and Remote Sensing work

       

      Geographic science utilizes GIS technology. Remote sensors are integrated into the GIS system and this together helps in understanding the maps, weather conditions, population density and many things related to earthly conditions.

      Maps-

      Maps are the geographic representation of data layers. Remote sensors measure the distance while GIS systems extract the data extracted and share with others through apps.

       

      Data-

      The data which is extracted gets integrated into different types of data layers using spatial locations. It generally has geographic components which are linked to spreadsheets and tables.

       

      Analysis-

      Analysis of the data helps in evaluating, estimating, predicting, interpreting and understanding the data extracted. Analysis of the data helps in decision making.

       

      Apps-

      Applications focus more on user experience. GIS visualizes the data and shares through remote sensors on mobile phones, tablets, web browsers, and on other platforms.

       

      Applications of GIS

       

      The automation of GIS is not only used for mapping. It is also used in various fields like

      • Petroleum- For finding petroleum refineries.
      • Telecommunications- For maintaining the network signals.
      • Transportation- To understand the traffic and mobility on roads.
      • Real Estate- To survey the land registrations.
      • Manufacturing- To identifying the mineral ores.
      • Natural & Sustainable Resources- To identify geographical resources.
      • Many other sectors like Education, Government, Health, Insurance, Public Safety, Retail, Electric and Gas Utilities etc make use of GIS systems for various purposes.

      What Does a GIS / Remote Sensing Specialist Do?

       

      Remote sensing specialists support scientists by designing and conducting remote sensing data gathering efforts. For example, they determine the best techniques, equipment, spectral band, and time of day for a particular mission. They may prepare flight plans, configure sensors, apply the techniques to collect data in the field, and process the resulting data.

      This data is used in a wide variety of fields, including all of the environmental sciences, agriculture, archaeology, urban planning, water management, meteorology, and even engineering and business.

       

      Career Scopes in GIS and Remote Sensing

       

      Remote sensing is increasingly used by private companies that sell imagery and data to Google, Bing, the federal government, scientists, academic and research libraries, and others. Specialists may also find employment at consulting firms, software development firms, and scientific laboratories, where they are expected to improve technologies, software, or data analysis techniques.

       

      Some specialists become professors or research staff in academia. These positions require at least a master’s degree, while tenured faculty has doctoral degrees.

       

      Most specialists in this highly computerized field spend much if not all of their time in office environments. However, collecting or verifying data in the field may be required on occasion.
