Laboratory Exercise 5

Creating and Editing Data


Making Maps Quickly


This laboratory consists of exercises from Chapters 15, 16 and 18 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 5 continues to look at how to create and edit data, and how to create professional quality maps quickly.

In Chapter 15 (Exercises 15a, 15b), you will learn how to create features.

In Chapter 16 (Exercises 16a, 16b, 16c), you will learn how to edit features and attributes.

Chapter 18 (Exercises 18a, 18b, 18c, 18d),  introduces you to the techniques of quickly making a map for presentation purposes.

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.
