How to Find Map Coordinates

Locations on maps are measured by what are known as map coordinates. The way that you find a map coordinate is by reading the degree measurement of the intersection where the two lines cross over a location, which indicates your location's latitude and longitude.

Instructions

1. Point to the location for which you want to find the map coordinates.

2. Follow the grid line from your location directly upwards and read the number at the top of the grid line to determine your latitude.

3. Follow the grid line from your location directly horizontal and read the number at the end of the grid line to determine your longitude.

Tips & Warnings

• Remember the difference between latitude and longitude by remembering that longitude runs long and lengthwise, horizontally.

• You may have to estimate your map coordinates if they lie between grid lines.
