A report comes in: Smoke is rising from a remote area of the Amazon. A government official pulls up satellite images to get a closer look. Was the fire sparked by lightning or set by loggers? Satellite data for the area near the fire reveals a road snaking through the forest — a road that didn’t exist a month earlier. The official sends a ground team to check for illegal logging.

Scenarios like that illustrate how satellite imagery could be a game changer in the global fight against deforestation, especially now that geospatial data is widely available, with remote sensors on planes, drones and a growing fleet of satellites. Such sensors, which once were the size of a minivan, are now the size of a car battery.

Scientists say mapping data can be used to help preserve forests. And because forests sequester tons of planet-warming carbon dioxide, forest preservation helps combat climate change. But the technology doesn’t always make it into the hands of the government officials whose job it is to fight deforestation.
