GIS started on mainframe computers; we could get one map every five to 10 hours, and if we made a mistake, it could take longer. In the early '90s, when people started buying PCs, we migrated to desktop software.

In this quote, Jack Dangermond reflects on the evolution of Geographic Information Systems (GIS) and how technological advancements have drastically improved its efficiency. He explains that in the early days of GIS, it was confined to mainframe computers, which were large and slow. Maps could take up to five to 10 hours to generate, and if there was a mistake, it could further delay the process. Dangermond’s statement emphasizes the limitations of early computing systems and how they hindered the speed and accuracy of GIS applications.

Dangermond contrasts this early, cumbersome process with the revolution that occurred in the 1990s when personal computers (PCs) became widely available. As PCs became more accessible, GIS software transitioned from mainframe systems to desktop software, which significantly improved the speed and usability of geographic data processing. This shift allowed users to work with GIS on their own computers, making the technology more accessible and increasing its practical applications in various fields such as urban planning, environmental studies, and resource management.

The origin of this quote can be traced to Dangermond’s role as the founder of Esri, a company that developed some of the earliest and most widely used GIS software. His personal involvement in the growth of GIS technology gives him a unique perspective on its transformation from a niche, complex system to a widely accessible tool that can be used on personal computers. This evolution marked a pivotal moment in the field of geospatial analysis.

Dangermond’s quote also highlights the broader theme of technological advancement and how innovations in computing have democratized access to powerful tools. The move from mainframe systems to personal computers made GIS more user-friendly and available to a wider audience, allowing professionals from diverse fields to incorporate geospatial data into their work. This shift reflects how technology continually transforms industries and improves efficiency, making complex tasks more manageable and accessible.
