Absolute location describes the location of a place based on a fixed point on earth. The most common way is to identify the location using coordinates such as latitude and longitude. Lines of longitude and latitude crisscross the earth.
What lines are part of the grid system on a map?
Coordinates – Longitude and latitude representing the angle of the point with respect to the core. All the longitude lines are equal in length and run from one pole to the other and all latitudes are parallel, creating a grid that is called graticule (a spherical grid).

What is index or key on a map?
: a map that shows (as by enclosing a small area in a rectangle on a large map) the location of one or more small areas in relation to a larger area and that typically points up special features in the small areas about which information is desired.
How do you use a map index?

How would you explain how do you use a Maps Index?

What are the features that are found on a map?
These essential features of a map are found on almost every map around us. They are- title, direction, legend(symbols), north areas, distance(scale), labels, grids and index, citation – which make it easier for people like us to understand the basic components of maps.
