Goals and Background: The purpose of this lab
was to give me a background in obtaining GIS and other data from an outside
source and format it into a way that I can map and analyze in ArcMap. The three
main objectives of this lab were to transform a standalone table containing data
into an attribute table that is functional to map, gain experience obtaining
data from an outside source by navigating the US Census Bureau's website and
downloading the data, and creating a map to compare two different variables in
Wisconsin counties.
Methods: The first part of this lab involved downloading data and creating two maps in ArcMap. First, I had to navigate through the US Census Bureau's website. I first clicked "Topics", expanded "Dataset", and selected "2010 SF1 100% Data". This gave me Census data from 2010. I wanted to narrow it down even more to give me data by county in Wisconsin so I clicked on "Geographies" and then "County". I selected Wisconsin and then "All Counties Within Wisconsin" and clicked "Add to your selections". This completed the search function, so now I could look for the specific data I wanted to find. The first data set I downloaded was "P1 for Total Population". I downloaded the data and extracted the files from the zipped folder. I opened the table "DEC_10_SF1_P1" in Excel and saved it as an Excel Workbook. This put it into a format where I was able to actually use the table in ArcMap. I then went back to the Census website to download the actual Wisconsin shapefile so I could actually map the data I had. Under the "Geographies" selection, I clicked the "Map" tab and then downloaded that map as a shapefile. I unzipped that file as well so I could work with it in ArcMap. All of this downloaded data was then put into my “lab_2” folder.
Then I started working in ArcMap. I opened to set the default location for all new files. Then I added my Wisconsin shapefile, as well as the P1 table to the data frame. The tables then needed to be joined together, and the mutual field between them was GEO_ID so I right clicked on the shapefile and chose "Join" from my options. I joined it to the standalone table and then exported the data to create a new shapefile containing the data I needed from the standalone table. I added the new shapefile to the map and then removed the join between the other tables. I ran into trouble trying to map the population data because the field type was a string, so I create a new long integer field in my attribute table and used the field calculator to populate it with the data I needed. I then opened the symbology tab on that shapefile and under "Quantities" chose "Graduated Color" and mapped my population using a natural breaks (Jenks) method because it appeared to work best. I then repeated the above workflow with another dataset from the Census, this time being median age by county in Wisconsin. I followed the same procedures as above in a new map file until I had mapped data of both Population and median age. I then changed the projections of both of these data frames to be the NAD83 Wisconsin Central State Plane because it seemed like the best way to display my created maps.

After going through all of this, I built a proper layout.
I added titles, scale bars, north arrows, source information, the date,
my name, and legends. I did my best to display all of this in a way that
would make it legible and appealing to viewers.
I then exported my constructed maps as a PDF to add to this blogpost.
For the second part of this lab I turned the map with the housing data into a dynamic map online. To do this, I first had to create a feature service through ArcMap. I signed into my enterprise account and then shared it as a published service to the "My Hosted Services" connection. I then unchecked "Tile Mapping" and checked "Feature Access" to ensure pop ups would be allowed on my web map.
I clicked the "Item Description" tab and entered a summary, description, and tags for my map. I then clicked "Sharing" and chose to share it with "UW-Eau Claire- Geography and Anthropology". I clicked the "Analyze" tool and then edited or deleted any of the features that gave errors since they weren't needed. Then I was able to publish my service on ArcMap.
Then I signed into my ArcGis Online enterprise account through a web browser. I clicked on "My Content" and then saw the feature layer that I was just working with in ArcMap. I chose "Add layer to map". This opened it in an online geobrowser. I opened the "Configure pop up" window and chose the features I wanted to be displayed in the pop-up windows on the map. I then saved it and shared it with "UW- Eau Claire- Geography and Anthropology". Below is a screen shot of the final result of that process.
