MITs Solar System
Scientists mapped 17,000 rooftops in Cambridge, Mass., providing residents with a web interface to look up their homes and project the cost and return on investment of photovoltaic solar panels.
Using satellite imagery and Light Detection and Ranging (LiDAR) data from a previous aerial survey to create a 3-D model of Cambridge. Then the team charted the exact shape of rooftops and possible sunlight obstructions, such as buildings and trees. They integrated this information with local weather station data, and crunched the numbers to create these projections.
We hope easy to access data like will encourage investment in solar energy as published by MIT Architecture & Planner
