1. Computerized Geographic Information Systems

2. What is GIS? Geographic Information System A data management information system Digital representation of geographic features Analyze earths geographic features Give meaning to the events which may be linked to the geography under study A tool to assist in decision-making Management of data that needs to analyzed spatially

3. Common Definition A computerized database management system for capture, storage, retrieval, analysis and display of spatial data. “Heart” of GIS is “Spatial Analysis”

4. Why Geographic Information Systems? Rapid growth of GIS worldwide GIS Specialist is one of the top 3 growing careers in the world/US High level of interest in new developments in computing “High Tech” feel to geographic information Maps are fascinating, so are maps in computers Increasing interest in geography and geographic education Tool to understanding and managing the environment

5. Questions GIS can Answer Location: What is at……………? Condition: Where is it …………? Trends: What has changed since ..? Patterns: What spatial patterns exists ? Modeling: What if ………………? Aspatial/Spatial Questions Location: What is at? What exists at a particular location Where is it? Find locations with specific identifiers/ buidlings, tree stands, soil. Trends Over time, use, before and after events Patterns Are events happening more frequently after certain conditions/ floods, rain, earthquakes, etc Modeling, if new road is added what conditions may change in the environment, more hardscape, etc. Aspatial-average number of people working with a specific software Spatial Average number of people working with particular software in a given area Location: What is at? What exists at a particular location Where is it? Find locations with specific identifiers/ buidlings, tree stands, soil. Trends Over time, use, before and after events Patterns Are events happening more frequently after certain conditions/ floods, rain, earthquakes, etc Modeling, if new road is added what conditions may change in the environment, more hardscape, etc. Aspatial-average number of people working with a specific software Spatial Average number of people working with particular software in a given area

6. MPS CGIS Course Introduction to GIS Database management Computerized mapping Investigate geographic problems and propose solutions Analyze geographic data Use Global Positioning Systems to make maps

7. National Geography Standards GIS Course Alignment

8. National Geography Standards GIS Course Alignment Standard 5: The Environment and Society How Physical Systems Affect Human Systems How Human Actions Modify the Physical Environment The Changes that Occur in the Meaning, Use, Distribution, and Importance of Resources

9. Standards For Technological Literacy Standard 4- Relationships among technologies and the connection between technology and other fields Standard 4- The Cultural, Social, Economic and Political effects of technology Standard 5- The effects of technology on the environment Standard 7- The influence of technology on history Standard 18- Information and Communication

10. GIS Class Assignments Population maps of Minneapolis and neighborhoods Maps of school location, 1 inch equals 100 feet Measure school grounds, determine square footage of hard scape and green space, calculate oxygen production of green space World Population Data Sheet Lesson activities from the Population Reference Bureau and the NEA Geography project View maps, images from satellite and aerial photography on websites

11. GIS Class assignments (con’t) Explore contributing disciplines and technologies Examples: geography, cartography, remote sensing, photogrammetry, surveying, geodsy, statistics, operations research, computer science, mathematics, civil engineering, science, geology, etc

12. GIS Class GPS Understand and operate GPS systems Global Positioning System-accuracy and flexibility of positioning for navigation, surveying and GIS data capture Import and export data from GPS systems Use GPS for geo-caching activities Formulate questions on land use and acquire and use GPS data to help answer the questions
