How do you make the invisible visible? How can we keep up with our ever-changing world, and how can we utilize the technologies of our time? Upon the completion of TechChange’s Mapping for Social Good course, we have found that some answers lie within the realm of digital mapping and geospatial data collection.

From Theory to Practice

The course features four …

Green infrastructure hasn’t always been a priority in urban development. Now, more than ever, green spaces are an essential component of urban design to build healthy, livable cities, and urban planners have jumped onboard. They have started integrating green infrastructure, green spaces (parks and recreational areas), tree canopies, vertical green walls, and green roofs into urban environments. And they are doing it with the help of maps!



What does urban design have to do with mental health? By 2050, at least two-thirds of the global population will live in cities, which means urban public health is fast becoming a priority. Policymakers, architects, designers, urban planners and others are starting to think seriously about how to design our cities in ways that reduce health issues like obesity or breathing problems, but one key aspect of …

They represented organizations like Oxfam, Korea NGO Council for Overseas Development, Chemonics, Danish Demining Group, Abt Associates, and many more.

How can mapping the geolocations of tweets tell a story about global atrocities? How can digital mapping be integrated as a learning tool for university classes?

As part of his final project for TechChange’s online course, TC141: Mapping for International Development in Spring of 2014, GIS professor Tom Mueller wanted his students to explore these topics. In Professor Mueller’s course, “Introduction to Geography” at the …
