History of Geographic Information Systems (GIS) Development: An Overview

/ / Public, Research, Teaching / , , / 3 minutes of reading

By Shahabuddin Amerudin The development of Geographic Information Systems (GIS) dates back to the 19th century, when the use of geographic information to address complex issues began. In 1832, French geographer Charles Picquet produced an early version of a GIS by creating a map-based representation of cholera spread in Paris using color gradients. This marked the earliest application of spatial analysis in epidemiology. In 1854, English physician John Snow expanded this concept by mapping a cholera outbreak in London and linking it to contaminated water. This illustrated the problem-solving potential of maps in epidemiology. The groundwork laid during this time
