I have a database of ~17,000 places and the query execution time is 0.054 seconds. It may be possible to increase performance by using a MySQL stored procedure as suggested by the "Geo-Distance-Search-with-MySQL" article posted above. $this->databaseLink = mysql_connect($this->database, $this->mysql_user, $this->mysql_pass)

Hopefully this helps! showClosest.php ".$row.""

I'm storing latitude as DECIMAL(10,8) and longitude as DECIMAL(11,8).

This answer shows how to implement the vincenty Great Circle Distance formula to get around this, however I chose to just use Haversine because it's good enough for my purposes. It should be noted that the Haversine formula experiences weaknesses around the poles. This solution uses the Haversine formula as presented in.

Here is my full solution implemented in PHP. To search by kilometers instead of miles, replace 3959 with 6371. It calculates the distance based on the latitude/longitude of that row and the target latitude/longitude, and then asks for only rows where the distance value is less than 25, orders the whole query by distance, and limits it to 20 results. Here's the SQL statement that will find the closest 20 locations that are within a radius of 25 miles to the 37, -122 coordinate. An in-depth mathemetical explanation is given by Wikipedia and a good discussion of the formula as it relates to programming is on Movable Type's site. The Haversine formula is used generally for computing great-circle distances between two pairs of coordinates on a sphere. To find locations in your markers table that are within a certain radius distance of a given latitude/longitude, you can use a SELECT statement based on the Haversine formula. Microsoft Excel and Google Spreadsheets both export to CSV format, so you can easily transfer data from spreadsheets to MySQL tables through exporting/importing CSV files. In phpMyAdmin, you can use the IMPORT tab to import various file formats, including CSV (comma-separated values). The sample data provided below is for about 180 pizzarias scattered across the United States. `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,Īfter creating the table, it's time to populate it with data. Your table should also have an id attribute to serve as the primary key.

That will let the fields store 6 digits after the decimal, plus up to 4 digits before the decimal, e.g.

To keep the storage space required for your table at a minimum, you can specify that the lat and lng attributes are floats of size (10,6). With the current zoom capabilities of Google Maps, you should only need 6 digits of precision after the decimal. When you create the MySQL table, you want to pay particular attention to the lat and lng attributes.
