In Tableau, longitude and latitude
In Tableau, longitude and latitude are essential geographic dimensions used to pinpoint and represent locations on the Earth's surface.
Latitude: Latitude measures the north-south position of a point and is expressed in degrees, ranging from -90 degrees at the South Pole to +90 degrees at the North Pole. The equator, at 0 degrees latitude, serves as the reference point. Positive values represent locations north of the equator, while negative values indicate positions south of it.
Longitude: Longitude, on the other hand, measures the east-west position of a point, also in degrees. It spans from -180 degrees at the International Date Line in the Pacific Ocean to +180 degrees at the Prime Meridian, which runs through Greenwich, London. Positive values denote locations east of the Prime Meridian, and negative values denote locations to the west.
In Tableau, these coordinates allow you to create geographic maps and visualizations. You can either use pre-existing latitude and longitude data or employ Tableau's geocoding capabilities to translate location names or addresses into these coordinates. By integrating latitude and longitude into your Tableau projects, you can effectively represent and analyze data within a spatial context, enabling insights into geographical patterns, such as customer distribution, sales territories, or regional trends.
