what is GIS
spatial system that creates, manages, analyzes all types of data
Geographic information science
focial point of GIS, the technical implementation, conceptual ideas
chang GIS description
computer sustem for capturing, storing, analyzing and displaying spatial information
where does GIS fall betweem physical and human geography
on the mid left side of human geography
technology and transformation of GIS
gepgraphical analysis is not new, however, recent tech like mass adoption of computers has altered how geographic analysis is used
domain of GISci
governments, millitary, commercial enterprises, scienties, land managers
today GIS is just one component of a broader subdiscipline called
geomatics
GIScience
geospatial technologies
GIScience
research, theoretical based, founded largely in geography
geospatial technology
specialized technologies that handle geographic data, GPS, surveying
applications
application in government, industry, academics
how does geography relate
integrative discipline
focus on location, scale, spatial relationships
is our data objective
no
data also always has a location attached to it, wether implicit or explicitly
transformation of data to wisdom
data - organized into..
information - analyzed into…
knowledge - used to create…
wisdom
components of GIS
computer hardware
users
GIS software
organization
darren adds
data
network
GIS deployment level: project
intial phase, individual or small work group working in isolation
limited and little sharing
GIS deployment : workgroup level
adoption of standards that promote conformity
still a bit isolated
GIS deployment : enterprise level
needs cooperation and coordination
standrds decvelopmed across multiple departments with centrally planned and managed components
ex. company, governments
GIS deployment: societal level
thousands of users across multiple organizations with common standards and protocols,
ex. Qatar
3 tiered software architecture
user interface
tools
data management system
software architecture : user interface
graphic collection of menus, toolbars, and access to GIS tools
software architecture: tools
the functions, capabilities that enable the handling and processing of geographic data
software architecture: data management system
the files and databases that store and organize the data
thick vs thin client
lan
thick client - all processing done on the desktop
thin client - processing is hosted on a central server
desktop vs server based GIS
mostly still on desktop, other than large companies and government organizations
more cost effective to be on a large server
in the long run it reduces software/hardware costs
