In this post, we will walk through the process of how to use the GD library in PHP to plot data on a MapQuest map.
By data, I am not referring to plotting just a location on a map, but plotting location specific data as well. Location gives you the "where", data will give you the "what" about that location. By using one of the icons from the MapQuest icon repository, you could plot a location with an icon indicating a restaurant or a gas station. By looking at a map such as this, we could quickly process where the gas stations and restaurants are and any patterns relating to the location of these businesses. For example, a high density of gas stations and restaurants along a line may indicate a major business route.
