The history of GIS technology is a fascinating journey from manual cartography to sophisticated digital systems. Its evolution has been driven by advancements in computer technology, data collection methods, and analytical techniques.

Early Beginnings:

• 1960s: The concept of GIS emerged in the 1960s with the development of the Canada Geographic Information System (CGIS) by Roger Tomlinson. CGIS was the first computerized GIS and was used to analyze land use data.
• 1970s: The Environmental Systems Research Institute (Esri) was founded in 1969 and developed the first commercial GIS software, ARC/INFO, in the 1970s.

Growth and Development:

• 1980s: The 1980s saw the widespread adoption of GIS technology in government agencies and private companies. Advancements in computer hardware and software made GIS more accessible and affordable.
• 1990s: The development of the Global Positioning System (GPS) revolutionized data collection for GIS. GPS allowed for the accurate and efficient collection of geographic data in the field.

Modern GIS:

• 2000s: The rise of the internet and web-based mapping platforms such as Google Maps and OpenStreetMap made GIS technology more accessible to the general public.
• Present: Today, GIS technology is used in a wide range of applications, including urban planning, environmental management, disaster response, and business analytics. Advancements in cloud computing, big data, and artificial intelligence are further transforming the field of GIS.

GIS in India:

GIS technology has been used in India for several decades, primarily in government agencies for mapping and resource management. The National Remote Sensing Centre (NRSC) has played a key role in promoting the use of GIS technology in India. Today, GIS is used in various sectors in India, including agriculture, urban planning, and infrastructure development.
