Lab 3 Downloading and mapping GIS Data

 

 

Introduction:
 
The goal of this lab assignment is to learn how to obtain GIS data and other stand alone data to be used in a GIS project.  It also is intended to learn how to use the U. S. Census Bureau's website to acquire information for this purpose. 
 
Methods:
 
First I downloaded the 2010 U. S. Census Data from the U. S FactFinder webpage (total population).  I downloaded the shapefile for the 2010 Census boundaries.  I then joined the data to the shapefile.  I then made a map of the 2010 Housing  Population.  I made the maps and then I went to Properties, Symbology, then labels to make the numbers easier to understand by taking out many of the zeroes and rounding the numbers to make the legend understandable.  I chose colors that were easy to see and read so the information was the same in both maps with the regards to color gradient.  
 
 

Map 1:  2010 Total Population Census Data (pink).
This map shows the total population of Wisconsin in 2010.  It shows which counties are more populated than others and if you know anything about Wisconsin the dark pink highlighted counties are where the two largest Milwaukee and Madison are located. 

Map 2: (Green)  I chose the housing population.  It shows similar results that the most populated counties also have the most housing units occupied.  The two darkest green ones are where Milwaukee and Madison are located.  The large dark green county (large block in the southern middle, closest to the bottom is Dane County  and the Milwaukee County is located on the Eastern most the state. 

In both maps above, Marathon County, Brown and Outgamie County and Winnebago counties also have a larger population of people and housing.  The two categories are very similar in the results as the total population would need housing so these results have a strong correlation to each other. 

I saved all the information in my folder and on GIS.
