GIS Review

GIS is really an interesting program for me. I was really impressed by its ability. Although all I have done was just following the instruction, I can feel that GIS has very strong functions.

First of all, I would like to mention the analysis function. The most important function for a GIS program is analysis. ArcGIS can automatically form the pictures from the database. This transformation system is the core because it makes data more practical. Actually, what used to see on a map are different lines, points and colorful shape, but ArcGIS made the work perfect by analyzing the information and data and then presenting them by graphs. It is really amazing.

Second, I would like to talk about my own experience. I used to learn such software such as AutoCAD. It is not really difficult, because when you start step by step, it seem easy to accomplish some work. Just as when I did this project, I did it fast and I was really happy when I finished every single small projects. However, ArcGIS is far more complicated than I thought. After I finished the project, I have viewed the whole settings and functions of the software, and I found that we can do more on that. This time, I just did some basic works such as drawing and adding details like legends and arrows. I seldom used the geoprocessing part. In this part, I found some interesting tools which are used to measure, draw or mark. I hope to learn more about the software.

At last, I think this experience is really good for me. At first time I do this, I failure to save it correctly. So, even though I had finished almost every part, I had to restart because I find it hard to restore. At first, I was annoyed and tried to do as quickly as I can. But the problem is that, because there were really a lot of important details I need to take care of, I made mistakes often. Then, I calmed down and viewed the instruction carefully. This time, I tried to understand every single step, but not just follow the instruction. This time I did smoothly and soon finished. I was proficient at the second time and more important, I understand. It took me at least 6 hours totally, though, I still appreciate it and is satisfied with my work.
