Laboratory Exercise 2
Getting Data into ArcView GIS
This laboratory consists of exercises from Chapter 8, and background
reading from Chapter 2, of the lab text, Getting to Know ArcView GIS,
with the data obtained from the accompanying CD-ROM (exercises
8a and 8b).
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.
In this exercise, you will learn how to add themes to a view. Remember
that geographic data sources fall into two categories: feature data sources
and image data sources. Feature data sources contain map representations
of geographic objects such as points, lines (arcs), and polygons, and the
tabular data associated with these features. An image data source is only
a raster image that has no other attributes and is used in these exercises
as a background image. No GIS operations are performed on image data sources.
(The extension Spatial Analyst will allow GIS operations on image data.)
In this exercise, you will create a map showing existing utilities for
use in planning upgrades and additions. No such map currently exists, so
you will have to create it from several different data sources. Then, sewer
trenches are planned to be dug in a certain area and you will be asked
to identify those property (and property owners) that will be affected.
For more information on these concepts, refer to the ESRI
With the supervision of your instructor, or lab coordinator, use the
Getting to Know ArcView GIS CD-ROM to carry out the directions of
exercises 8a and 8b. The path to the exercises may vary from PC to PC,
so check with the lab instructor or lab coordinate.
Q1. When you create a new view, the gray area to the left of View 1 is
called the .
Q3. How did you make the air photo a background, with the other themes
drawn over it?
Q4. Many GIS operations you will perform act only on active themes. How
do you make a theme (or themes) active?
Q5. Name the three basic shapes that represent map features.
Q6. In a Desktop GIS, link
features and their attributes.
