What is 'geocoding' in the context of Tableau mapping?
Answer: Converting location names or postal codes into latitude and longitude coordinates
Geocoding is the process of converting place names, addresses, or postal codes into geographic coordinates (latitude and longitude) that can be plotted on a map.
How do you correctly plot latitude and longitude data as map points in Tableau when the coordinates are stored as two separate numeric fields in your dataset?
Answer: Drag the Longitude field to Columns and the Latitude field to Rows
In Tableau, placing the Longitude field on Columns (X-axis) and the Latitude field on Rows (Y-axis) automatically generates a map with points plotted at the specified coordinates.
What mark type in Tableau is used to create a path or route map that connects multiple geographic points in a defined sequence?
Answer: Line
The Line mark type connects data points in sequence based on a path order field, drawing routes or trajectories across a map.
Which of the following best describes a spider map (origin-destination map) in Tableau?
Answer: A map that draws lines from a central origin point to multiple destination points
A spider map draws connecting lines from one or more origin points to multiple destination points, revealing hub-and-spoke connectivity patterns on a geographic map.
What built-in geographic hierarchy does Tableau recognize for United States location data?
Answer: Country > Region > Division > State > County > City > ZIP Code
Tableau's built-in US geographic hierarchy includes Country, Region, Division, State, County, City, and ZIP Code, reflecting standard US Census administrative levels.
In Tableau, when auto-generated Latitude and Longitude fields are created after assigning a geographic role, in which section of the Data pane do they appear?
Answer: In the Measures section
Tableau places auto-generated Latitude and Longitude fields in the Measures section of the Data pane because they are continuous numeric values.
What is the purpose of the 'Map Layers' panel in Tableau Desktop?
Answer: To control which background map elements (coastlines, country borders, streets, etc.) are shown or hidden
The Map Layers panel lets you toggle on or off built-in background map elements such as country borders, state borders, coastlines, highways, and place labels.
