Geog 222 Lecture Outline: Computers and Mapping
Update: 2/24/14

Introduction

Computers have had and continue to have a major impact on mapping

We can still make maps by hand...but

There is very little non-computer mapping anymore


A question to ponder: what is the future of the paper map?


Today and next few lectures: An Overview of Computers and Mapping




Computers and Mapping

Two very broad categories:


Map Images

Map Images: a digital equivalent of a printed map





Maps connected to Databases:




Most common: a digital link between a spreadsheet/database and a digital map



Geographical Information Systems (GIS) and Geographic Information Science (GISci)

Pre-Computer GIS: The fundamental ideas behind GIS were established before computers existed. Computers make GIS analysis much easier to perform, but GIS does not absolutely require a computer

Classic example of early GIS: Ian McHarg: Using GIS to locate a new road



There is an important human and social component of GIS: it is not only hardware, software, and concepts of spatial analysis.



Defining GIS

GIS developed out of a diversity of software applications:


GIS is defined in two broad ways: GIS and GISci

1. GIS as geographic information systems (GIS) an integrative set of technologies: combine the functions of the different software packages above into one package



2. GIS as geographic information science (GISci): the theories and concepts behind geographic information systems

GIS Jargon:


A few things to keep in mind about GIS...
