The Availability of Food

These maps from 2010 show the availability of grocery store locations and also the percentage of people who had a car to get there. The topic of food availability is already an interesting conversation.. is there enough food? Is there enough food, but it just isn’t distributed evenly? Why is healthy food more expense then unhealthy? Why has food become more of a business then of a way to survive? Take a look at these maps, because they bring another problem into the mix! Transportation and accessibility.

The information for the maps was collected from the USDA Food Environment Atlas and the maps were created by Meharry Medical College.

Take a look at this interesting map we made on Mappler in collaboration with Planning Communities! The map is full of GIS layers that you can toggle to show various information such as crime, food, recreation, transit, and URISA health data in DC. The picture below shows URISA data marking sidewalks, intersections, homeless locations, and garbage. Visit the map to view all the data !

Climate Change- How Sea Level Rise Could Change Where & How We Live

Climate change is always a hot topic, literally. With the melting of the ice caps, the unstable polar vortex which influences the jet stream, and with temperatures becoming more extreme, it is no mystery that sea level is continuing to rise. We wanted to visualize the threat of sea level rise by making a map that shows the potential projections of how our coasts in New Jersey and New York could eventual look.

We zoomed in to focus on New York City and the Northeastern part of the New Jersey coastline. We gathered the information for sea level rise from and then created the map using our Mappler technology. The first image is what the coast currently looks like, with the second and third images showing possible sea level rise projections. Image 2 shows sea level rise projections for 2100 if climate change continues without us taking action. This projection shows a 2m rise, with the dark blue border showing the potential new coastline. Image 3 is the worse case scenario for the year 2100, meaning that this is what scientists are projecting if again no action towards stopping or slowing climate change takes place and if the Greenland ice sheet melts. Image 3 shows a 7m sea level rise, and as you can see the land taken is massive. These maps show the scary reality that we could face if climate change is not taken seriously. You think that the population and its growth are bad now? How about when we then have to face displacement of part of the population because land where they use to live is covered in water? Take action, educate on climate change, and do your part!

Happy Earth Day! NYC Tree Map

Trees help city areas with reducing pollution, they help to improve health, and overall bring a sense of calm to a place known for fast-pace living. Here is a map we created on Mappler using data from the TreesCount! 2015 by the NYC Department of Parks and Recreation. This map is color-coded based on condition of the trees.

Looking at the density screenshot, it is interesting to view where the best versus worst rated trees are located. The photo on the left shows where the worst rated trees are, and the right shows the trees rated as the best. Lets keep adding trees to our concrete jungle! Click here to see the site.

Adult Obesity Map

This is a map that we created based off of data from the Center for Disease Control. This information shows the percentage of adults that were classified as obese in the year 2010. Blue indicates areas with the lowest percentages, while red shows areas where obesity in adults is more prevalent. It is interesting to think about the fact that we have so much food here in the US, yet getting a hold of healthy options is more difficult then it should be. #foodforthought

City Population- IIED

This really interesting map on International Institute for Environment and Development’s website,, shows populations of cities with more then 500,000 people from 1800 to the predicted 2030. The visual that this map gives shows how big our world really is. With a little more than 7 billion people right now, by 2030 that amount will surely grow. Makes you think about what the health, environment, food and water situation will look like when the predicted population for 2030 will be more then 8 billion. I think that if we can increase education efforts on population rise and conservation efforts, we can help to lessen that number or at least be more prepared.

Below is a screenshot from of cities in 1800 that had more than 500,000 people. London and Beijing had more than a million and Guangzhou and Paris are between 500,000 and a million people.

Looking at 2015, you can see that 1,029 cities had populations larger than 500,000. Take a look at their site and see what the projection is for the year 2030! Thanks IIED for the cool map!

all information for this post from contact click here for the site. Allergy Maps has some pretty interesting maps related to air quality. If you are curious about the amount of tree, weed, or grass pollen, mold, and breathing index within the United States, take a look at their site! Below is a screenshot of one of their maps for mold spore counts, green indicates low counts and red shows areas of high counts. Go to to see all of the maps! What does your area look like?
