What MySQL Data Type Best Handles Latitude/Longitude to Eight Decimal Places?

Precision Handling for Latitude/Longitude with 8 Decimal Places in MySQL

Question: I'm handling map data that requires storing latitude and longitude values with precision up to eight decimal places. What MySQL data type is most suitable for this purpose?

Answer:

MySQL offers a specialized data type known as POINT that is specifically designed for storing spatial data, including latitude and longitude coordinates. This data type ensures precise representation of geographic locations. Here's how you can utilize POINT for your scenario:

CREATE TABLE `buildings` (
  `coordinate` POINT NOT NULL,
  /* Index for faster spatial queries (optional) */
  SPATIAL INDEX `SPATIAL` (`coordinate`)
) ENGINE=InnoDB;

To insert the provided coordinates:

INSERT INTO `buildings` 
(`coordinate`) 
VALUES
(POINT(40.71727401 -74.00898606));

By utilizing the POINT data type, you can ensure the accuracy and precision required for your map calculations.
