FIVE PHASES OF DEVELOPMENT • Research Frontier (Late 50’s to Mid 70’s)
Research Frontier • Individual-led developments • Limited international collaboration • Lack of data in machine-readable form • Lack of computing resources 1968 1958 Roger TomlinsonThe “father” of GIS
Research Frontier • Jack Dangermond • Founded ESRI in 1969 Environmental Systems Research Institute
FIVE PHASES OF DEVELOPMENT • Research Frontier (Late 50’s to Mid 70’s) • Experimentation and Practice (Early 70’s to Early 80’s)
Experimentation and Practice • National agencies drive development • Government-funded research • Formal scientific experiments • Role of the individual diminished 1970 1972 Landsat SPOT - 1986
FIVE PHASES OF DEVELOPMENT • Research Frontier (Late 50’s to Mid 70’s) • Experimentation and Practice (Early 70’s to Early 80’s) • Commercial Phase (The 80’s)
Commercial Phase • Corporate software development • Isolated systems and datasets
FIVE PHASES OF DEVELOPMENT • Research Frontier (Late 50’s to Mid 70’s) • Experimentation and Practice (Early 70’s to Early 80’s) • Commercial Phase (The 80’s) • User Dominance (The 90’s)
User Dominance • Strong competition among vendors • Distributed databases • Network Accessibility

Web-Based Internet GIS & GIScience • Fully-distributed architecture • Focus on interoperability • Mobile GIS • Research on best practices for GIS • VGI – Volunteer Geographic Information • Ex: Wikimapia
