  4. Software • ArcGIS 10.5.1 • Access cods for student licenses will be provided. • Runs only on a Windows operating system (8.1 or higher or 7 Enterprise Edition). • Some departments have older versions. • Three computers in Lab 138 • Karen Kidder for key code. • Log on with Mainestreet id and pw Lecture 1

  5. COURSE OBJECTIVES: • This is an introductory course designed to provide the student with: • An overview of the development and basic principles of geographic information systems. • Practical experience in the use of ArcGIS 10.x (one of the most popular commercial GIS packages). • The implementation of a GIS project using available data. Lecture 1

  6.

Lecture 1

  7. Topics • Introduction to GIS • Dealing with spatial data • Geodesy, Datums, Map Projections and Coordinates • Database management • Data Input, Editing and Output • Spatial Data Analysis • Data Standards and Data Quality • GIS Project Development Lecture 1

  8. Assignments • Labs • Eight to 10 lab exercises. • Lab exercises have differing point values (25-50 Points), depending upon the length and difficulty of the exercise. • Project • The project should be implemented using GIS software. • The project can be related to your research, or be on another topic of interest. Lecture 1

Access to Facilities among Bangor’s Low Income Population • Mapping China’s Long March • An Analysis of Campus Crime and the Placement of Blue Lights. • Mapping the Fay Hyland Botanical Garden • The Joys and Sorrows of Geocoding • Landslides along the Maine Coast • Glacial geology in Miers Valley, Antarctica • ATM Locations in Bangor Lecture 1

  11. Citation Analysis • Flooding potential along various coast lines. • Monitoring Age Change in Downeast Maine • Measuring the Impact of Pollution Closures on the Harvesting of the Soft-Shell Clam • The Modernization of Agriculture in Nineteenth Century Maine • Direction Relations using ArcGIS • Growing Grapes in Northern Portugal Lecture 1

  12. Project Dates • Proposal – Sept. 21 • List of data files and their source – Oct. 12 • Data dictionary – Nov. 9 • Oral presentations begin – Dec. 4 • Final report and CD with project – Dec. 15 Lecture 1

  13. Exams • There are two exams scheduled: • Exam 1 - Oct. 17th • Exam 2 – Nov. 30th Grading • Lab exercises              25% • Exams (2)                    25% each • Project                         25% • Plus and minus grading will be used. Lecture 1

  14. An Introduction to GIS Chapter 1 Lecture 1

  15. What does GIS stand for? • Geographic (Geography) • Information • System Lecture 1

  16. What is a Geographic Information System? Geographic Information System (GIS) – A computer-based system for the collection, storage, organization, maintenance, and analysis of spatially-referenced data, and the output of spatially-referenced information. Data – Any collection of related facts; the basic elements of information. Information - Data that have been processed to be useful; provides answers to "who", "what", "where", and "when" questions Information can only come from accurate data (GIGO). Lecture 1

  17. What are the components of a GIS? We understand GIS to be computer facilitated system But it is NOT only software and hardware Also includes: • Data – both spatial and aspatial • Trained personnel • Supporting Institution • Protocols for use Lecture 1

  18. GIS Software Tools (the frustrating part) GIS started at universities as research tools – Harvard, Yale, Minnesota, Clark University GIS software have evolved to robust (sort of) tools capable of a wide variety of tasks Primary flavors ESRI (ArcGIS)Intergraph QGIS Bentley Map MicroimagesAutocadMapInfo ERDASIdrisiManifold Smallworld GRASS GeoMediaAUTOCAD MAP 3D Maptitude Lecture 1

  19. The Map Lecture 1 http://reliefweb.int/map/syrian-arab-republic/syrian-refugees-region-20-january-2014

  20. The Database

  23. Other FeaturesReports http://desktop.arcgis.com/en/arcmap/10.3/guide-books/extensions/business-analyst/GUID-389C0E81-9313-4C5C-94B0-51D7650E3B53-web.png Lecture 1

  24. The Power of GIS • The interaction between the database and the map, along with the ability to create graphs, tables and reports.

  25. How does a GIS answer spatial questions? GIS allows us to abstract information from the physical world and display it in layers or themes. It allows us to: • Input and edit both spatial and attribute data. • Display data on a screen or print a map. • Analyze the data for making decisions and searching for patterns. • Create models and ask “what if”. Lecture 1

  26. What types of questions can be answered by a GIS? • Where are particular features found? • What geographic patterns exist? • Where have changes occurred over a specified time period? • Where do certain conditions apply? • What will be the implications if an organization takes a certain action? Lecture 1

  27. What types of data are used in a GIS? • Coordinate data • Connection information • Descriptive information • Temporal information • Images • Documents • URL’s Lecture 1

  28. Coordinate Data for a GIS • Spatial data – you can attach coordinate information. • 2D maps (X,Y) Lecture 1 http://www.mappery.com/map-of/Hong-Kong-Hotel-Map-2

  29. 3D –Maps (X,Y,Z) Lecture 1 https://www.flickr.com/photos/seeminglee/4112874847

  30. How is spatial data represented in a GIS? Vectors Raster Grids/Tesselations • Points, Lines & Areas/Polygons Lecture 1

  31. Applications of GIS • Urban Planning, Management & Policy • Zoning, subdivision planning • Land acquisition • Economic development • Code enforcement • Housing renovation programs • Emergency response • Crime analysis • Tax assessment • Environmental Sciences • Monitoring environmental risk • Modeling storm water runoff • Management of watersheds, floodplains, wetlands, forests, aquifers • Environmental Impact Analysis • Hazardous or toxic facility siting • Groundwater modeling and contamination tracking • Political Science • Redistricting • Analysis of election results • Predictive modeling Civil Engineering/Utility Locating underground facilities Designing alignment for freeways, transit Coordination of infrastructure maintenance Business Demographic Analysis Market Penetration/ Share Analysis Site Selection Education Administration Attendance Area Maintenance Enrollment Projections School Bus Routing Real Estate Neighborhood land prices Traffic Impact Analysis Determination of Highest and Best Use Health Care Epidemiology Needs Analysis Service Inventory Lecture 1

  32. GIS Before Computers Cholera Map of Dr. John Snow (UK 1850s) Lecture 1

  33. There’s Another GIS/GISc • Geographic Information Science • comprehending the underlying conceptual issues of representing data and processes in space-time • the science (or theory and concepts) behind the technology • GI Science is the focus of the research in this department. Lecture 1
