Map and Explore: Hidden Hydrology
Jason King,  Portland

Our cities are filled with hidden stories. Some of these tales are unlocked through conversations with long-time residents and oral histories, while others emerge through the written word, embedded in documents and biographies from the shapers and boosters that made our cities. Some hide in maps, a chronology of layers of changes over time, intimately spatial and tied to places,...

Enabling Efficient Urban Biodiversity Monitoring Through Modern Natural History and Citizen Science
Timothy Bonebrake, Hong Kong

The escalator that stretches from Victoria Harbour in central Hong Kong to the high-priced mid-levels neighborhood accommodates approximately 70,000 commuters daily. Surrounded by tall buildings, you would not at first glance expect to find much in the way of life other than never-ending humanity. However, even on this congested pathway on any given day you are likely to see red-whiskered...
