Laboratory Exercise 2

Displaying Data

and

Getting Information About Features


Background

This laboratory consists of exercises from Chapters 6, 7 and 8 of the lab text, Getting to Know ArcGIS Desktop, with the exercise data obtained from the accompanying CD-ROM.

ArcView is a powerful desktop geographic information system (GIS) developed by Environmental Systems Research Institute (ESRI). With ArcView, you can load any data that's linked to geographic locations and display it graphically as maps, charts and tables. You can also edit the data , change the way it's displayed, append additional data, create some of your own, perform queries to answer specific questions, or meet certain criteria, and analyze information statistically as well as spatially. Results can be shown as quality graphic presentations to print out or display your screen.
 

Lab 2 continues to explore the many ways data can be displayed, and introduces the techniques of getting information about features.


In Chapter 6 (Exercises 6a, 6b, 6c, 6d), you will learn how to classify features and rasters.

In Chapter 7 (Exercises 7a, 7b, 7c), you will learn how to apply labels to maps.

Chapter 8 (Exercises 8a, 8b,8c),  introduces you to the ways of selecting features, and creating reports. Note: Section 8b is important for the Term Project!

It is estimated that it will take from 3 to 6 hours to complete this lab. Please plan accordingly, so that all the answers to this lab are submitted at the same time.

For more information on these concepts, please refer to the ESRI website.
