2 Outline  GIS overview  GIS data and layers  GIS applications and examples  Software overview  GIS tutorial 1 overview 2 GIS TUTORIAL 1 - Basic Workbook

3 GIS OVERVIEW Lecture 1

4 What is GIS?  Geographic Information Systems (GIS) are computerized systems designed for the storage, retrieval and analysis of geographically referenced data  GIS uses advanced analytical tools to explore at a scientific level the spatial relationships, patterns, and processes of cultural, biological, demographic, economic, geographic, and physical phenomena 4 GIS TUTORIAL 1 - Basic Workbook Got that?

5 Tools for GIS  Hardware  Computer  Digitizer  Scanner  Printer/Plotter  Software  Desktop GIS  Internet GIS  CAD Software  Database Software  Multimedia (photos, videos, 3D models) 5 GIS TUTORIAL 1 - Basic Workbook

6 Unique capabilities of GIS  GIS stores related geographic features in separate collections of files called map layers  Map layers can be reused easily and assembled into any number of map compositions and overlaid for analysis 6 GIS TUTORIAL 1 - Basic Workbook

7 GIS answers the following  Location: What is at...? Where is it?  Condition: Status of features?  Trends: What has changed since...?  Patterns: What spatial patterns exist?  Modeling: What if…? 7 GIS TUTORIAL 1 - Basic Workbook

8 Scale of GIS data Global to local 8 GIS TUTORIAL 1 - Basic Workbook

9 Vector data  Map features  Points, lines, polygons  Feature attributes  Every feature has attributes (e.g. name, area, population) ShapeNameClassPop2000State PointNew YorkCity8,008,278NY PointLos AngelesCity3,694,820CA PointChicagoCity2,896,016IL 9 GIS TUTORIAL 1 - Basic Workbook

10 Raster Data Stored electronic image or picture taken as an aerial photograph or satellite image C omposed of a rectangular array of square cells, called pixels, with a number in each cell representing the solid color fill of that cell 10 GIS TUTORIAL 1 - Basic Workbook

11 GIS DATA AND LAYERS Lecture 1

12 GIS example  Identify polluting companies and their proximity to populations in poverty, water features, or schools.  Start with  Databases  Map layers 12 GIS TUTORIAL 1 - Basic Workbook

13 Databases Not easy to interpret 13 GIS TUTORIAL 1 - Basic Workbook

14 Data shown as GIS layers 14 GIS TUTORIAL 1 - Basic Workbook

42 Tabular Data

43 Compared to a picture

44 Traffic Accident Analysis

45

46 Transportation Route planning Route locater Identification of funding

47 Economic Development  Sales tax provides 40% of the city’s revenue  Licenses and permits make up another 11%  Other revenue sources are eroding  Good jobs make for a stable community  Retaining existing businesses saves jobs  New businesses and development can replace blight  Economic development is proactive

48 How can GIS help? TM  Better visualization and analysis of current and future conditions  Aggregate a variety of geographic features and demographics  Notify residents and businesses of activities and opportunities  Avoid shotgun approach  Better redevelopment planning  Make development easier  Reduce duplication of data  Provide site selections  Create marketing opportunities  Speed your decision making  Get a competitive edge

49 Tabular Data

50 Maps  Use maps to enhance text based marketing  Use vicinity maps to contrast with other communities  Demonstrate the unique strengths of your community  Show target areas

51 More Maps Redevelopment project areas Special design areas Demographics Anticipated or desired development Local attractions (i.e., universities, airports) Current projects Traffic volumes

52 Yet More Maps Location

53 Analysis  Know thyself!  Identify under-served markets  Find potential development sites  Identify areas in need of redevelopment  Overlay projects with other activities to avoid conflicts  Make better informed decisions  Cluster projects  Identify labor pool

54 Some industries prefer to locate in close proximity to similar industries or need to be close to suppliers Industry Clusters

55 Business Analyst Online Demo

56 Flexible bureaucrats??? Inside Versus Outside Needs Staff needs are different from public needs Private goals and public goals sometimes differ Staff can interpret needs and be flexible

57 Economic Development on the Internet Listings of parcels Contact information Parcel search Building permits Demographics Describe your community

58 Elections Polling place location Identification of potential voter fraud Analysis of election results
