to identify the precise location of any place on earth
In an electrical power transmission system: the grid is what the feeder feed into.

A hybrid grid mini-system
A: Hemisphere means half of a sphere. REPHRASE THE QUESTION
National grid is nothing but a net work (power system) of many different generation points across a region / country to feed to different end user points.
identify the precise located of any place on earth
Well it's not really a grid it's lines of longitude and latitude so you can find the coordinates of whatever.
Geographers use a number grid on maps to help locate specific points and determine distances between locations accurately. The grid system allows for easy reference and navigation, making it simple to pinpoint exact coordinates on a map. This grid helps users understand the spatial relationships between different places and features on the map.
Geographers use the prime meridian as the starting point for measuring longitude around the globe. It helps establish a reference point for determining locations in terms of east-west distance. By using the prime meridian in conjunction with the Equator, geographers can create a grid system to pinpoint any location on Earth.
its either by studying landforms, the grid system, lines of latitude, or photos taken high above earth.

Because geographers are sexy.. ;)
geographers use computer-based systems called what to connect information with locations.

To locate the points.
Geographers (those who study weather/land/people) usually do not often need to use a coordinate grid. However those studying geometry (a branch of maths) do use them.
