Exploring 3D GIS Visualisations

What is one of the benefits of using 3D data visualisations in GIS?

• It simplifies data entry processes.

• It helps to identify patterns that may not be apparent in 2D.

• It reduces the need for data storage.

• It eliminates the need for 2D maps.

Which view in ArcGIS Pro is best for visualising data at a local scale?

• Map view

• Local scene view

• Global scene view

• Satellite view

What is the purpose of a cartographic offset in a 3D scene?

• To change the colour of the map

• To adjust the horizontal position of features

• To vertically adjust the height value of the entire layer

• To add labels to the map

When is vertical exaggeration particularly useful?

• When the surface is perfectly flat

• When the horizontal extent of the surface is greater than the amount of vertical change present

• When the map is viewed in 2D

• When the map is viewed in black and white

Which view is suitable for visualising large geographic extents where the curvature of the Earth is important?

• Map view

• Local scene view

• Global scene view

• Street view

What is one of the main uses of vertical exaggeration?

• To reduce the size of the dataset

• To amplify small changes in elevation on a surface that is relatively flat

• To change the projection of the map

• To add more layers to the map

In which scenario would you use a map view in ArcGIS Pro?

• For a side view of a building

• For a top-down view of either small or large extents

• For a 3D view of a mountain range

• For a detailed street-level view

What does vertical exaggeration help to achieve when z-values represent an attribute other than elevation?

• It helps to reduce the z-values to zero

• It brings z-values into proportion with x,y coordinates

• It changes the colour of the z-values

• It eliminates the need for x,y coordinates

What is a benefit of adding realistic environmental effects to a 3D scene?

• It increases the file size

• It invites imagination and understanding

• It makes the scene harder to interpret

• It reduces the need for data analysis

Which view allows you to visualise both 2D and 3D data from a real-world perspective?

• Map view

• Local scene view

• Global scene view

• Aerial view
