Built Environment 3
Background
Built Environment, Part 3 (ArcGIS) See the Guide and video for ArcGIS in the Toolbox within the course in 2BU. Increasingly in public health, mapping tools are being used to better understand where people live and the resources (e.g., parks) available to them within their communities. ArcGIS is one mapping tool that is available for examining the availability of resources as well as the demographic make-up of an area. ArcGIS can be used to identify high-risk populations to target for community health interventions. For example, the health status of low socioeconomic status (SES) communities is worse off than higher SES communities. Since income is a significant predictor of health outcomes, public health practitioners often use US Census Data to identify low SES areas for community-level health interventions. For this part of the built environment assignment, students will become familiar with ArcGIS.
Assignment
Students will need to use ArcGIS to identify 4 parks in their selected community that will later be used to conduct a “virtual assessment” using the PARA tool (Built Environment, Part 5).
Deliverables
Students will submit a document (MS Word or PDF format) with screenshots of three maps that include:
For each map, include information about the income level, education level, and population density for the parks (see example in the Toolbox).
Data Category | Description |
---|---|
ArcGIS Online Data |
What are they? These are streaming layers that can be included in our map. Does it cost any money? These are 100% free to use. Is it easy to use? The very easiest. Who creates this data? ESRI (the company who creates ArcGIS) populates a lot of the available data. Additionally, anyone with an ESRI account (including you all) can publish data via ArcGIS Online.
Are there disadvantages? Yes! There is very little analysis that can be conducted on data accessed this way. No worries though, as we are not conducting any analysis today. |
Basemap | A basemap is the underlying map image that all other data is overlaid. |
ACS (American Community Survey) | Beginning in 2010, the Census ACS survey replaced the Decennial Census for sampled research data. This is what we will use for income and education data. |
