Vector Analysis Quiz

What does vector analysis primarily use to represent real-world features?

• Tables and spreadsheets

• Graphs and charts

• Points, lines, and polygons

• Images and videos

What is the purpose of buffering in vector analysis?

• To calculate distances between points

• To merge different datasets

• To visualize data in 3D

• To create zones around features based on proximity

Which operation combines geometries and attributes of two feature layers?

• Buffering

• Union

• Overlay

• Intersect

What does the Nearest Neighbor Analysis determine?

• The area covered by points

• The average distance between all points

• If point patterns are random, regular, or clustered

• The total number of points in a layer

What does spatial autocorrelation measure?

• The size of the study area

• The average distance between features

• The total number of features in a dataset

• The relationship among values of a variable based on spatial arrangement

Which of the following defines the Tobler's 1st Law of Geography the best?

• Everything is related to each other but near things are more related to each other than the further ones

• Everything is related to each other but further things are more related to each other than the nearby ones

• Events outside of a geographic area of interest can affect what happens inside that area

• Everything is not related to each other

What does the Getis-Ord Gi* statistic identify?

• The variance of a dataset

• The total number of data points

• Clusters or hotspots of high or low values

Which method is used to compute a geometric intersection of input features?

• Union

• Identity

• Buffering

• Symmetrical Difference

What is the first consideration for overlay operations?

• Data size

• Geometric shape

• Feature type

• Attribute values

What does the term 'buffer zone' refer to?

• A statistical measure

• A method for merging datasets

• An area within a specified distance of selected features

• A type of spatial analysis
