GIS Introduction






The ArcMap Tutorial was an interesting experience as each step is plotted out for you. It was very tedious but it helped me to gain an understanding of the program. It is very interesting to see how maps are made in that most of it is based off of information and data that has been gathered and as a map maker, the duty is to present the information in an aesthetically pleasing way that also helps to lay down the ideas better by showing the visual connections of said data. 
I found it very interesting to see the different layers involved in making a map. To be able to turn certain layers on and off proves the dynamic nature of map making and proves that each map can be changed to reveal a different concept. Each layer gives the map a new meaning and a new focus.
The potential of this program is extensive as it can create in-depth and versatile maps for any kind of data set. The maps can be changed and modified, aesthetically and fundamentally in the event that the data sets or points have changed. It gives users the ability to make many different kinds of maps for the same data, in that each map can be changed to relay a certain type of information or even just to present a different look.
The pitfalls however, are just like any map making program or map in general. Maps are biased and relay information in the hopes of conveying a very certain message. All maps are created by an individuals with opinions and stand points, there for maps, just like a work of art, will carry with them aspects of the creator. Since all individuals are different, most maps will be different, even if the data is the same.
