The history of GIS is rooted in the need to manage and analyze geographic data more efficiently. Here's a brief overview of its evolution:

• Early Mapping (Pre-1960s): Traditional cartography involved manual map creation and analysis, which was time-consuming and limited in scope.
• Emergence of GIS (1960s): The first true GIS, the Canada Geographic Information System (CGIS), was developed in the early 1960s. It was used to analyze land use data and manage natural resources.
• Development of GIS Software (1970s-1980s): Companies like ESRI (Environmental Systems Research Institute) began developing commercial GIS software, making the technology more accessible.
• Advancements in Computing (1990s): The rise of personal computers and the internet led to the widespread adoption of GIS technology. Data sharing and collaboration became easier.
• Integration with Other Technologies (2000s-Present): GIS has been integrated with other technologies like GPS, remote sensing, and cloud computing, expanding its capabilities and applications.

Key Milestones:

• 1960s: Development of CGIS.
• 1980s: Emergence of commercial GIS software.
• 1990s: Widespread adoption of GIS technology.
• 2000s: Integration with GPS and remote sensing.

Impact on Society:

• GIS has revolutionized fields like urban planning, environmental science, and disaster management.
• It has enabled organizations to make more informed decisions based on spatial data.
