Lab 1: Introduction to ArcGIS

Introduction

This lab will introduce the ArcGIS software including the ArcMap and ArcCatalog modules.  You will learn the following skills in ArcView:

• Displaying map data
• Navigating a map
• Looking at feature attributes
• Browsing map data
• Searching for map data
• Adding data to ArcMap

Instructions

Read Chapters 1 and 2 of Getting to Know ArcGIS Desktop.  Then do the tutorial exercises in Chapters 3 and 4.  You will need to load the data from the Getting to Know ArcGIS desktop book onto the hard drive of the computer on which you are working.  The default directory for the tutorial data is C:\GTKArcGIS.  Don't put it there.  Put it on a drive that you have access to.  Make sure you keep the CD since if you lose of corrupt your data then you will need to reload it.

Deliverables

Answer the following questions and produce the following outputs.  Hand them in to the instructor at the beginning of the next lab section.  Labs should be typed, include your name and lab number, be well organized, and staples together. I suggest using Microsoft Word interactively while doing the exercises.
