Tutorial GIS Chapter 2

What does the term data mean in the context of GIS?

• Raw figures without structure

• Groups of details describing attributes of variables

• Final output of map production

• Only numerical measurements

What happens to data when they are processed and interpreted to give meaning?

• They become symbols

• They become information

• They become website

• They become attributes

Which statement correctly describes quantitative data?

• Data that describe categories or names

• Data expressed as numbers or measurable quantities

• Data that show relationships between colours

• Data that cannot be counted

How does GIS organise data for analysis and display?

• In thematic layers and attribute tables

• In random folders

• In simple text files

• In a single image layer

Why does GIS use thematic layers?

• To reduce file size

• To separate and analyse spatial relationships between features

• To remove attribute tables

• To make maps more colourful

Which of the following is a correct example of a GIS dataset?

• A list of student names

• A printed topographic map

• Land-parcel boundaries and location with ownersho+ip data

• A bar chart of rainfall

What does spatial data describe?

• The appearance of objects

• Descriptive information about features

• The location and geometry of features on Earth

• The quality of imagery

In what forms can spatial data be represented?

• Chart and graph

• Text and table

• Vector and raster

• Numeric and symbolic

Which of the following is an example of a discrete spatial feature?

• Temperature surface

• Elevation model

• River line

• Rainfall distribution

What type of information does attribute data provide in GIS?

• Colour of symbols on a map

• Coordinate reference values

• File size and format

• Descriptive information about spatial features
