The coordinate grid system was created by the French mathematician Rene Descartes.
The Greek philosopher who developed a grid system to locate places on a map was Hipparchus. He created a system of latitude and longitude coordinates to help in mapping the Earth's surface. This grid system laid the foundation for modern cartography.
Mention in two points how the grid system on a map helps us to locate places.
A grid is a network of horizontal and vertical lines that provides a reference system for locating points on an image. The points where the lines intersect are used to identify specific locations on the image based on their coordinates on the grid. Grids are often used in design, mapping, and image editing to ensure accuracy and consistency in positioning elements.
The axis of the Earth is an imaginary line that runs from the North Pole to the South Pole, and it is tilted at an angle of about 23.5 degrees. This tilt helps define the coordinate system of latitude and longitude, which are essential for locating places on the globe. Latitude lines run parallel to the equator, while longitude lines run from pole to pole, allowing for a precise grid system. By using these coordinates, one can accurately identify any location on Earth.
The numbering and lettering system on a map is called an alphanumeric grid. This assigns a letter and a number to each square to make locating points on the map easier.
Grid references are a system of locating points on a map using intersecting lines of longitude and latitude. They are formed by numbers or letters, with each line representing a different unit of measurement (meters, kilometers, etc.). Grid references help identify specific locations with precision.
The two imaginary base lines used to create a grid for locating points on Earth are the equator (latitude) and the prime meridian (longitude). The equator divides the Earth into the Northern and Southern Hemispheres, while the prime meridian divides it into the Eastern and Western Hemispheres. Together, these lines form a grid system that helps to pinpoint specific locations on Earth.
In social studies, a grid system is a method used to organize and analyze data on maps or charts. It involves dividing a map or chart into a series of intersecting horizontal and vertical lines to create a reference system for locating specific points or areas. This allows for easier navigation, communication, and analysis of spatial information.

Three means of locating a place is: Longitude and latitude; Global Positioning System (GPS); Map Grid Reference.
