1. GIS Lecture 1 Introduction to GIS Buildings. Poly Streams, Line Wells, Point Roads, Line Zoning,Poly MAP SHEETS

2. GIS Overview

3. What is GIS? GIS (Geographic Information System): computer information system that can input, store, manipulate, analyze, and display geographically referenced (spatial) data to support decision making processes.

4. Tools for a GIS Hardware - Computer - Printer / Plotter - Digitizer - Scanner GIS Desktop Software CAD Software Multimedia - Photos, Video, 3D Models World Wide Web GIS Personnel

5. GIS Data Raster Images - grids “pixels” satellite images aerial photos Vector - grids features: points, lines & polygons attributes: size, type, length, etc.

6. GIS Data Sources Digitized and Scanned Maps purchased, donated, free (Internet) created by user Data Bases – Tables of data GPS (Global Positioning Systems) Field Sampling of Attributes Remote Sensing & Aerial Photography

7. Conventional Information Systems Answer the following questions: - Who ? - What ? - When ? - Why ? - How ?

8. GIS answers the following Location: What is at...? Condition: Where is it? Trends: What has changed since...? Patterns: What spatial patterns exist? Modeling: What if…? Exploring data using GIS turns data into information into knowledge

9. Data Data Data Location Data How Many? – What Kind? – Where? Scale of Data Global to Local Data Presentation Words, Charts, Graphs, Tables, Maps, Photos

10. Databases Not easy to interpret
