Data Exploration in GIS

What is the primary purpose of data exploration in GIS projects?

• To collect raw data

• To identify general trends and explore data relationships

• To create final maps

• To conduct statistical tests

Which of the following is NOT an element of data exploration?

• Data visualization

• Descriptive statistics

• Graphs

• Dynamic graphs

What does a boxplot summarize in a data set?

• Five key statistics including minimum and maximum

• Only the range of values

• Mean and median only

• Standard deviation and variance

In the context of data exploration, what is the role of dynamic graphs?

• To display static data only

• To allow users to manipulate data points directly

• To create pie charts

• To summarize data in a table format

What type of query focuses on geographic relationships in GIS?

• Attribute Query

• Spatial Query

• Raster Data Query

• Dynamic Query

Which SQL query would you use to find all campsites with more than 5 parking spaces?

• SELECT * FROM Campsites WHERE Parking_Spaces > 5

• SELECT * FROM Campsites WHERE Parking_Spaces >= 5

• SELECT * FROM Campsites WHERE Parking_Spaces < 5

• SELECT * FROM Campsites WHERE Parking_Spaces = 5

What is the significance of using maps in data exploration?

• They are less effective than graphs

• They are only for aesthetic purposes

• They replace the need for statistical analysis

• They help visualize spatial data relationships

How does a spatial query differ from an attribute query?

• It does not require SQL

• It is less complex

• It focuses on non-spatial attributes

• It involves geographic relationships

What does the term 'containment' refer to in spatial queries?

• The distance between two features

• Whether one feature is within another

• The overlap of two features

• The total area of a feature

In a raster data query, what type of data is being analyzed?

• Text data

• Continuous grid data

• Categorical data

• Discrete data
