Laboratory Exercise 4
Analyzing, Creating and Editing Data
Making Maps Quickly
consists of exercises from Chapters 13, 16 and 18 of the lab text, Getting to Know ArcGIS
Desktop, with the exercise data obtained from the
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 4 continues to explore the techniques of
creating, analyzing, and editing data, and how to create professional quality
In Chapter 13 (Exercises 13a, 13b), you will
learn how to project data.
Chapter 16 (Exercises 16a, 16b, 16c), introduces you to
the techniques of editing features and attributes. Note: Section 16c is important for the Term Project!
Chapter 18 (Exercises 18a, 18b, 18c, 18d),
introduces you to the techniques of quickly making a map for
presentation purposes. Note:
Chapter 18 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.
