Map Projection

This week, the assignment I did is creating different map projection. This assignment is much easier than the one last week, and I just finished it less than 2 hours. All in all, I would like to consider this assignment as a further step on ArcGIS. From the assignment, I learned a new function about the software—new projection design.

At first, I had a problem on the cities choosing part. I cannot quickly select the cities and dragged them out of the contribution table. I tried to select the cities at the table at first and clicked the right button. I wanted to find a way to export these two single elements in the table, but failed at last. TA helped us by teaching us that we can use the ‘selection’ and make the two elements a new layer.

Then the other problem I faced is about the projection choosing. I don’t know which one is equal distance projection or which is conformal projection. I had been stuck for a while. I had searched online and asked classmates about it. 

Finally I can recognize them correctly. It was really simple to create the map and insert scale bars, arrows. At last I changed the colors and the symbols of cities in order to make it clear to recognize.

By these three weeks getting touch with the ArcGIS, I found it interesting and would like to excavate more about it. Take and simple example, by the assignment this week, I saw what the really world is like. As we always saw the regular map which is the so-called world map, we can hardly imagine that Antarctic is such big place, and that the total land in the earth is in just a small proportion. GIS has increased our knowledge and I really enjoy it.
