2. What is a GIS? “…a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information…” “…a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information…” “A smart map. A combination of a graphic display and a database. The map and the database are intimately linked so when you click on the map, the information about that point is highlighted on the screen.” “A smart map. A combination of a graphic display and a database. The map and the database are intimately linked so when you click on the map, the information about that point is highlighted on the screen.” “A system of hardware, software, and procedures designed to support, capture, manage, manipulate, analyze, model, and display spatially referenced data for solving complex planning and management problems.” “A system of hardware, software, and procedures designed to support, capture, manage, manipulate, analyze, model, and display spatially referenced data for solving complex planning and management problems.”

3. Information System An information system is established to achieve the objectives of collecting, storing, analyzing, and presenting information in a systematic manner An information system is established to achieve the objectives of collecting, storing, analyzing, and presenting information in a systematic manner The term geographic, which implies a spatial component to the system, are also characterized with two additional crucial properties The term geographic, which implies a spatial component to the system, are also characterized with two additional crucial properties The reference to geographic space, which means the data are registered to a geographical coordinate systemThe reference to geographic space, which means the data are registered to a geographical coordinate system The representation at geographic scale, which means the data are normally recorded at small scales and may be generalized and symbolized.The representation at geographic scale, which means the data are normally recorded at small scales and may be generalized and symbolized.

6. GIS Concepts Represent the real world by processing data and applying it in map form Represent the real world by processing data and applying it in map form Allows geographic features in real world locations to be digitally represented so they can be presented in map form and manipulated to address some problem Allows geographic features in real world locations to be digitally represented so they can be presented in map form and manipulated to address some problem

7. GIS Concepts A GIS stores the locations of geographic features as geometric entities A GIS stores the locations of geographic features as geometric entities The geographic features (geometric entities) are linked to a database The geographic features (geometric entities) are linked to a database Information about various entities can be obtained by selecting them or various analyses can be run on the entities Information about various entities can be obtained by selecting them or various analyses can be run on the entities

9. GIS Concepts A GIS allows a user to overlay a series of layers, each of which represents some real- world feature, to digitally view any given area. A GIS allows a user to overlay a series of layers, each of which represents some real- world feature, to digitally view any given area.

Space is a limited and interrelated commodity Space is a limited and interrelated commodity Information can be easily shared between different groups Information can be easily shared between different groups Complex information can be presented in a variety of formats that are easily read by an audience Complex information can be presented in a variety of formats that are easily read by an audience Return investment on data; data can be applied for other purposes Return investment on data; data can be applied for other purposes Improved decision making Improved decision making

Longley “Almost everything that happens, happens somewhere. Knowing where something happens is critically important” – Paul A.

14. The Singleton family name derives from a place in northwest England, and understandably the greatest concentration of this name today remains in this region. But why should the name be disproportionately concentrated in the south and east of the United States? Geographical analysis of the global pattern of family names can help us to hypothesize about the historic migrations of families, communities, and cultural groups.

26. Advancements in Cartography Increase in developmental societies led to the need for newer and better maps (i.e., building of roads, railroads, and canals required the locations of towns, lakes, etc., to be accurately known. Increase in developmental societies led to the need for newer and better maps (i.e., building of roads, railroads, and canals required the locations of towns, lakes, etc., to be accurately known. Advances in mapmaking led to utilization of maps in various ways. One of these ways was to overlay a series of maps to show a large amount of information on a single display.

32. Advancements in Cartography First manual GIS developed during construction of Irish railway (1850s). A series of maps were compiled that showed information on population density, geology, and political boundaries. First manual GIS developed during construction of Irish railway (1850s). A series of maps were compiled that showed information on population density, geology, and political boundaries. Considered first manual GIS because it involved the simultaneous use of a series of maps to solve a spatial problem.
