Google Map
View Local Natives on Tour 2009 in a larger map
GIS systems used to be reserved for only military purposes; it was not distributed to the public. Today this technology has become more available to the general public. There are GPS systems to put in your car as well as in your phone, a recent phenomenon. Stemming off of this, there is neogeography - a way for amateurs to create their own maps and share information with others without GIS knowledge. Applications such as Google Maps allows the user to create their own map any way they want displaying any information they choose. For example, a user may map a vacation by placing photos they took while there on the map location of the place the photo was taken. All of this information is created voluntarily by the user.
Some concerns arise from this new technology in the are of privacy. With Google Earth, one may view any location as well as the people at that location. Some people expressed concern when people were caught doing things they did not want people to know about. This growing craze of updating the entire world of your whereabouts at every moment does indeed give reason for concern. Some people go even further than worrying about individual privacy and worry about terrorist organizations using this information to plan an attack. In addition to this, this volunteered information tends to lack documentation ( such as in terms of when it was created) reducing the legitimacy and trustable of sites that use this information. Because of this, there are no standards or rules to follow, so there is no way to know if the mapped information you are viewing is accurate. Neogeography is created by amateurs for amateurs, so naturally there are bound to be pitfalls and consequences.

Three Maps I find interesting from the internet
For this assignment I will be displaying three maps I found online.
This map displays all of the biomes around the globe. The different colors represent a different biome, such as boreal forest or temperate grasslands. I find this interesting because this is something I have learned about in some of my classes in the past, making it a topic I enjoy learning about. The importance of knowing this information, and having it displayed in a way such as this, lies in the ability to compare climactic factors with other factors, such as where agriculture is, where cities are, or where the developing countries are. Patterns may be noticed that would otherwise be missed, such as what countries are in power verse what countries are in the tropical areas.

This next map reveals the break up of religions around the globe. Each color represents a different religion and places it in a geographical context. The data for this is taken from the percentage of the global population in 2002. Trends emerge when looking at this map that can be used to explain global conflict and other related issues. You can compare religions to everything from what countries constitute the European Union, what countries trade, what countries are in conflict, etc.

This last map was used in one of classes (it was not exactly the same, but it was the same idea and layout) and I thought it would be a good example for this assignment. It maps the movement of early humans from their origins in Africa throughout the rest of the world. The map includes several notations and arrows, as well as a date timeline, to display as well as explain this migration of modern humans. The first thing I noticed about this map was it's orientation: Africa is on the left rather than at the center like the majority of the maps we encounter. It is almost unrecognizable and seems incorrect, but there really is nothing less correct about this orientation. It makes much more sense, having Africa be on the left showing the forward (displayed as movement to the right) progression of modern humans (which also mirrors the way we read text). The other thing I find interesting about this map is to compare this with the extinction of mega fauna around the globe.
