The lab presented had several objectives. In order to reach each goal several things were needed to be learned, and steps needed to be accurately followed. Each goal and how they were accomplished, are listed below.
The First thing that needed to be accomplished was downloading 2010 Census data (total population) from the US Census Bureau. To do this, go on the US Census Bureau website. Once on the website, pick the appropriate geography needed to to represent what is desired. For this lab, the geography needed are all of the counties in Wisconsin. Then choose the right data set. For this lab the data needed is total population. Once this is downloaded, the excel table that comes with the zip file needs to be modified. There is an unnecessary row of labeling that should not be there. This must be removed so arcgis can read the table. Once the table is completed, it must be re-saved as a MS Excel file.
The second thing needed is to download a shapefile of the 2010 Census boundaries
from the US Census Bureau. The shapefile needed is all of the counties in Wisconsin. This should be selected on the US Census Bureau website and then downloaded and unzipped. once unzipped there should be the proper shapefile of Wisconsin counties. This can be added in arc catalog and then added to the map.
The third thing needed to do is join the downloaded data to the Census shapefile. Doing this will allow the user to create a map of population in Wisconsin counties. To join two tables, they must share a common field. In this case the common field is GEO_ID. Join the tables together then the fourth objective can be completed.
Mapping the data is the fourth objective. It can not be be done right away because there is a missing field in the county shapefile. It must be created by adding a field and using the calculator to add the population data to this new field.
Objective 5 is to create another map of the Wisconsin counties, with different data variable that is not population. In order to do this the same steps as 1-4.
Objective 6 is to display both of these separate maps on the same map document. To do this formatting is necessary, so both of the maps fit. Then basic map elements needed to be added such as a title, legend, and a north arrow. The results are below.
This particular example compares total populating in Wisconsin by county and total housing units in Wisconsin by county. Things to notice are the results are nearly identical. Not surprisingly, there are similar numbers of housing as there are people.
The final objective that needed accomplishing was to build a web map with one of the variables. To do this only one map was needed, so the total population was used, and housing units was removed. To upload the population map to arcgis online, the first thing needed to do is sign in to arcgis online though arc map. Once signed in, it is possible to share the map and upload it online. After this is completed, the next thing to do is login to arcgis online through a web browser and view the map that was uploaded. Once viewing the uploaded map, things can be configured and removed to display the necessary data desired. In this case, the only thing that needed to be displayed was population of the county and the county name. Everything else was removed. Once everything looks correct, the map is saved and shared to whoever is desired. In this case it is the UW-Eau Claire-Geography and Anthropology department.
