Geography 7 Lab 7

 
The legend of the map indicates that the darkest shade of green has the highest percentage of black population in the United States for about 53.197% to 86.4887%. The majority of the black population is located around the south-eastern coast. I think this result will not surprise most of the people have the basic history knowledge of the United States. The west coast contains a low percentage of black population which most of them, about 4% to 12% of the total black population, are situated in middle and south California. The distribution range of the map is from 0.01% to 86.4887%.

The Asian population in the United States is evenly distributed around the East coast (New York city and the nearby states) and the West coast (San Francisco, Los Angeles, and the state of Washington). It is easily to understand that the Asian has a traditional tide with those regions when they first migrated to the states but it quite surprised me when I discovered some of the concentrated population in southern Taxes. The range of the map is from 0.0085% to 46.0387%.

This map shows the distribution of some other race population by county. By this census, some other race population refers to population that are not identified as Asian, Black, and White.  Overall, most of the population of other race are found along the south-western coast, which is the border between the United States and Mexico. We can also find a dense some other race population in the state of Washington. The range of the map is from 0.00795% to 39.0795%.

Most of the result of census 2010 are not surprised me with a basic knowledge of U.S. history but this lab is really helpful to let me actually work with the real census data with the ArcGIS application. After completing those labs, I have gained rich knowledge of dealing with complicated geographical data by the application.

To conclude the course, my impression of GIS changed. Before taking this course, I thought GIS is all about playing and dealing with some maps but now I understand that the study of GIS is far more than this. The use of GIS in our daily life really helps people to organize and analyze spatial data. Also, the application ArcGIS is one of the most important elements in the field that let us deal with the complicated data directly with an user-friendly program. After completing such a number of labs, I realize how to use the application to due with different kinds of map projection methods, the analyze of population census, and etc.
