This app maker says his work saved thousands during Hurricane Harvey — and he's not done yet


After Hurricane Harvey, it was hard to locate people amidst the swaths of water covering the city. Two Houstonians developed a “web-based geolocation service” that used data from social media to locate and visualize people’s location. Since then, they’ve updated their service and it’s been used for other catastrophes, helping rescue as many as 37,000 people.
