#ARCGIS MAPS HOW TO#
Every day, maps are created to help make decisions about everything from where to construct levies to how to limit the environmental impacts of new construction projects. You can view more maps, data, and tools for policy mapping in the United States at the Esri Maps for Public Policy site.Ī similar analysis can be performed to analyze problems and propose solutions in your own city. You can re-create this map yourself by completing the Policy Mapping - Safe Streets to Schools lesson. These decisions will be easier now that the city has a useful tool for deciding where these resources are most needed. The city may decide to expand school speed limit zones or hire more crossing guards. These schools are the ones with buffer zones highlighted in white on the final map. Many schools closer to the downtown area, however, are more susceptible to traffic accidents.įinally, the people who created the map found the five schools with the highest number of accidents in their buffer zones.

The surrounding street networks were analyzed to create buffers around each school. Next, school locations were added to map. For that, it was necessary to predict where students would be walking to school. But from the map in the example image, you would not know where to allocate resources to improve student safety. Policy maps are intended to help policy makers in governments or businesses decide where and how to direct their efforts. Pedestrian accidents are in red and bicycle accidents in orange. In the example image, larger circles represent fatalities, while smaller circles represent injuries. But when it was filtered and symbolized, more useful information and patterns emerged. This data was initially displayed as a collection of red points, such as in the following image: This map did not begin with schools, but with traffic accident data. We can use maps to perform analysis and help improve our communities, prepare for emergencies, and plan for the future. Maps don't only identify and communicate problems-they also help solve them. We can use maps to share our own stories and to connect with one another. Maps offer us a way to engage with our communities, be they local, national, or global. They are things that we contribute to and create. Maps aren't just things that we read and consume.Have you lost someone to this epidemic?

It allows us to feel the scope of the tragedy not through numbers, but through individual lives. This map displays data in a way that allows each person to be more than a statistic.
