GA County Health Rankings

The Georgia Department of Public Health (GADPH) created maps of the health factors and outcomes in all of the counties in Georgia. The list of health factors include health behaviors, clinical care, social and economic factors and the physical environment. However, there is no mention of any oral health indicators. Health outcomes are defined as length and quality of life. Maps of these indicators and outcomes are helpful to better understand the impact of health issues in various populations. In the map below, the green counties represent health outcomes and the blue counties represent health factors.

Antartica’s Largest Iceberg Will Soon Be Non-Existent

On its course to the equator, this massive iceberg breaking off of Antartica’s Ross Shelf is nearing destruction.


The iceberg, called B-15, has been drifting away from Antartica for around 20 years, covering more than 6,600 miles. The iceberg has gradually fractured into multiple smaller sections, and the section pictured is called B-15Z.


This map tracks the course of B-15Z over time, and the iceberg is now passing the South Georgian Islands. The iceberg is nearing the equator, and the warmer tropical waters will quickly melt away the gargantuan ice mass,

Ash Plumes and Sulfur Dioxide of the Volcan de Fuego Eruption in Guatemala



In an article published on, the spread of Sulfur Dioxide into the atmosphere due to the recent volcano eruption in Guatemala was seen via the Suomi National Polar-Orbiting Partnership Satellite (Suomi NPP). What we see in the image is the amount of SO2 in the air expressed in Dobson units. A Dobson unit is a unit of measurement for the total amount of ozone in the atmosphere above a point on the earth’s surface. One Dobson unit is equivalent to a layer of pure ozone 0.01mm thick at standard temperature and pressure.

This image was generated thanks to Suomi NPP/NOAA/NASA Earth Observatory

The Image below is a view from the satellite of the atmosphere after the eruption on June 3rd, 2018.




Surveillance of Hepatitis A Outbreaks: State-by-State Counts from 2017-2018



In the midst of newsworthy Hepatitis A outbreaks in Kentucky, San Diego, and Michigan, this map depicts the number of Hepatitis A incidents across the United States from 2017-2018. The number fluctuations in each state over the last year is alarming considering that there are few national regulations being put into place in the realm of food safety. Catherine Huddle from Food Safety News explains that although the CDC recommends that all children should be vaccinated at the ages of 1 and 2, ” the CDC has not recommended Hepatitis A vaccinations for food service workers” (Huddle, 2018). We can only hope that more information and awareness of Hepatitis A outbreaks can help force a decline in it’s prevalence. For more information of state reported Hepatitis A incidents you can visit the Food Safety News web page.

Locating HPSAs for Dental Care in Georgia using GIS

Health Professional Shortage Areas (HPSA) or Medically Underserved Area/Population (MUA/P) are designated by the Health Resources and Services Administration (HRSA) based on HRSA’s shortage designation criteria. According to HRSA,

“HPSAs may be designated as having a shortage of primary medical care, dental or mental health providers. They may be urban or rural areas, population groups, or medical or other public facilities. MUAs may be a whole county or a group of contiguous counties, a group of counties or civil divisions, or a group of urban census tracts in which residents have a shortage of health services. MUPs may include groups of persons who face economic, cultural or linguistic barriers to health care.”

The HRSA website allows you find health related information using GIS. Information is sectioned by dental, mental and primary health, by state and even county.

Take a look at the map below to see the HPSAs for dental health care in Georgia.

Applicaiton of GIS in Health: Proximity Analysis

GIS is a powerful tool with various applications. One very useful of such is the ability to produce proximity analysis. It essentially gives an idea of how close one variable is to another, cartographically. For example, look into the below map.

Proximity Analysis of Injury with playgrounds, Pittsburg, PA


I created the above map using the tutorials in ESRI website for ArcGIS & the content from GIS Tutorial for Health. The above map shows the location of injury to residents and looks for how it is related to the playgrounds in the city. A simple analysis using ArcGIS software yielded the following results:


This helps us have an idea that most of the injuries happen away (1200 feet away, if not atleast 600 feet away) from the playground. Another interpretation of the results would be: 16% more injuries occur more than 600 feet away from the playground as compared to within 600 feet.  we can conclude by simple spatial reading that playgrounds have a probable protective effect against injuries. Let promote playground on the week of the French Opens!

Map of Dental Sites in Georgia

The Georgia Department of Public Health (GADPH) offers a plethora of resources for individuals residing in Georgia who are seeking access to dental care. One important piece of information that GADPH offers are maps of dental sites throughout all regions of GA. These maps provide locations of dental care sites that are non-profit, state and/or federally funded. Those dental care sites consist of dental schools, public health dental offices, federal qualify health centers (FQHCs), charitable organizations and dental hygiene schools.
