The aim of this thesis is to investigate American Colonization, that is the discovery and colonizing of America. American colonization often refers to American westward expansion, acquisition of the Philippines, etc. By using the word "Colonization" that ambiguity is hopefully avoided. Colonization of Americas began in 1492 by European when Spanish voyages headed by Christopher Columbus (an Italian Sailor) sailed west to find a new trade route to the East but unexpectedly found the Americas. The primary goal of this thesis is to explore Google map facilities to build a map based application showing the colonial period on an interactive timeline, including maps to show Norse exploration and Columbus four voyages to the west in search of new trade routes when he unknowingly found the Americas. To show on maps the original thirteen colonies that were setup in the United States and are divided into three colonial regions — New England, Middle Colonies and Southern colonies. The application can be accessed using any standard web browser and informs the user about the colonization and colonial period of the United States. Maps are implemented to make the application more responsive to the user.
