Do you know how many satellites in the space? Approximately 6,600 satellites have been launched and some are operational and others remain as debris in the space. They are used for numerous purposes including military, navigation, weather and research etc. Among them, environmental monitoring is one of the main purposes.

Satellite found the new view of uncontacted indigenous communities Locating and keep monitoring the residents are significant process to protect Amazonian groups from other harmful factors. Survey with low-flying planes cost a lot and stress people under survey.

Fortunately, scientists have started to use high-resolution satellite image to get information over the past decade. This costs less than the aerial survey and provides the high-quality images.

The satellite images offer the community's detail information to the researchers. For example, one community appeared in 2006 and abandoned and overgrown again in 2012. An anthropologist at the University of Missouri says that the population of native people decreased dramatically so that he wants to measure more isolated areas.

This way will also be effective to monitor external threat such as logging on indigenous villages, which will protect the uncontacted groups and provide high quality of images at a lower cost.

Despite high quality of images, the individuals or face will not be identified to protect privacy. And also be careful to keep the information of isolated villages in order not to harm them.
