Lab 4 Introducing ArcMap

Introducing ArcMap

This map was created using ArcMap, which is the main component of the ArcGIS software. It is a geospatial processing program that helps in organizing, editing, and analyzing geographical information. I've found that it is a great program because of its many functions. Following the instruction in the tutorial was difficult, but I was able to perform various tasks such as importing data, analyzing different attributes, editing the map and exporting the final map. Also, the editing tools of ArcGIS helps users to draw accurate lines and curves and hence reduce mistakes caused by a lack of drawing skills. In addition, accurate and comprehensive analysis can be done in just a few steps, and aesthetically pleasing graphs or maps can be created to present the result. 

Another merit of the ArcGIS is that it enables users to create highly customized maps. The color of different features could be changed one by one manually or by using a set style. Titles and other texts can be added and dragged to proper position. Also, there are different types of legends, scale bars and north arrows so that the user can choose the visual they think works the best. All these functions make the maps created more diverse and more eye-catching. Furthermore, ArcGIS is very convenient in the sense that any change in the data will immediately result in change in corresponding map features. The user, therefore, can see the changes directly and can respond quickly if the editing of data is mistaken.

Nevertheless, ArcGIS has pitfalls too. The biggest problem is that the program is too complicated for the beginning user. While providing plenty of functions to enhance the presentation, ArcGIS could be difficult to use, especially for people who lack basic computer skills. Many of the functions are represented by icons which are difficult to recognize and some others are only feasible to use when certain requirements are met. In comparing to the tools used in making "my maps' Google Map, ArcGIS is less accessible for the public. In addition, since it does not have the function of adding related videos or pictures to features, the map created will be less less dynamic and viewer-centric.

Overall, I have had an enlightening experience working with ArcGIS, realized that it is a useful tool for processing complex geospacial data and creating illustrative maps. However, it requires a certain level of computer skill and is quite complex with users.
