Applying network analysis to business planning:
Land use suitability analysis:
World first thematic map: Erupting volcano, Konya town, Turkey; 6200 BC.
World first disease spot map: Yellow Fever Deaths in New York 1798.
A Pioneer in GIS study: Doctor John Snow’s map of cholera outbreaks from 1854 London changed how we saw a disease.
Today, with the computing power and modern analytic methods available to us, we can take the analysis even further: The concentration around the Broad Street pump becomes even clearer, showing why Geographic Maps are an important tool to have in your analytic toolbox.
Jacqueline Tyrwhitt, Town & Country Planning (1950 textbook)
GIS’s origins lie in thematic cartography. Many planners used the method of map overlay using manual techniques. Manual map overlay as a method was first described comprehensively by Jacqueline Tyrwhitt in a 1950 planning textbook
Ian MacHarg, Design with Nature (1969)
Pioneer in environmental study and site suitability analysis using GIS analysis. McHarg, a Scottish landscape architect and a writer on regional planning, used blacked out transparent overlays for site selection in Design with Nature
Data representation in GIS is a translation process: turning real-world data into map and other human readable features (Vector and Raster).
Spatial data allows abstract representations of geographic features in real world locations to be digitally represented and stored in a database — The Ironman 2 Clips
GIS integrates all these layers’ of information and provide tools for analysis.
There are three types of information stored within spatial data:
The data file used in ArcGIS Pro is called: shapefiles. It is comprised of several support files.
