A little study about Grid Maps
This document is the summary of my study about grid maps.
Grid maps are basically maps with a grid that allows to locate positions based on simple Cartesian coordinates.
Here's a simple example !
This first known cartographers to mention this kind of map are Zhang Heng (78-139) and Pei Xiu (224-271). The main goal was to increase the map accuracy in order to calculate the distance between two locations.
Grid plan are basically the adaptation of this kind of map to the conception of a city plan. The most famous ones being the plans of big cities. New-York development was based on a grid plan to ensure the city's growth since 1811.
Grid plan, as said earlier, are basically the adaptation of grid map to city plan, where the streets are forming the grid. In those cities, the streets must run at right angles to each other.
Grid references is an other name used to characterize a map using cartesian coordinates.
