Laboratory Exercise 1

Getting Started with Maps and Data

and

Displaying Data


Background

This laboratory consists of exercises from Chapters 3,4 and 5, and a reading assignment of chapters 1 and 2of the lab text, Getting to Know ArcGIS Desktop, with the data obtained from the accompanying CD-ROM.

ArcView is a powerful desktop geographic information system (GIS) made 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 1 Introduces you to the main components of ArcView, namely ArcMAP and ArcCatalog.


In Chapter 3 (Exercises 3a, 3b, and 3c), you will learn how to display data in ArcMAP, about layers and attribute tables. 

In Chapter 4 (Exercises 4a, 4b, 4c), you will learn to search for map data using ArcCatalog and add it to ArcMAP.

In Chapter 5 (Exercises 5a, 5b, 5c, 5c, 5d) introduces you to to applying the appropriate symbols to represent map features and attributes. Note: Section 5b 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.
