PostgreSQL offers multiple methods to store geospatial data, and the simplest way involves using separate columns for latitude and longitude, enhancing accuracy.
Latitude and longitude are critical in pinpointing locations on Earth; latitude measures north-south position while longitude indicates east-west position relative to the Prime Meridian.
Coordinates can also be expressed in smaller units like minutes and seconds, or in decimal format; if positive, they denote north/east, while negative values represent south/west.
Using the double column type in PostgreSQL for storing coordinates allows for greater precision in small values, making it an effective choice for accurate geospatial data.
