Satellites are starting to watch your every move

There are real-time

The
dramatic advances in satellite imaging technology in the last 10
years have privacy advocates worried about 24-hour surveillance. Right now, US
federal regulations help keep things in check, so that while
commercial satellite imagery is powerful enough, for instance, to see
a car, it's not detailed enough to identify the make and model, according to a
report from the MIT Technology Review.
Satellite
companies say they keep a person's data separate from any identifying
characteristics, but Peter Martinez of the Secure World Foundation said that
doesn't matter.
"The risks arise not only
from the satellite images themselves but the fusion of Earth observation data
with other sources of data," Martinez said in an email. Then
there's the sheer volume of satellites overhead. Imaging company Planet Labs
confirmed that it has 140 imaging satellites currently in orbit. The report
says this is enough to pass over every place on Earth once a day.
"Even with Planet's
highest resolution imagery (1m resolution), it remains impossible to distinguish
individual people, car number plates, or otherwise identifying information. Our
imagery is ideal for monitoring large-scale change on a daily basis. This
includes seeing daily change across buildings and roads, forests, in
agriculture, bodies of water and more," a spokesperson for Planet Labs
said in an email.
Meanwhile, satellite imagery is
getting closer to a level that investors and businesses will want to exploit.
The goal, Mapbox's Charlie Loyd told MIT Technology Review, is to make a
"living map" of Earth.
The publication points out that
the observational satellites can do good, too. They can help farmers monitor a
crop's growth cycle, geologists better examine rock textures, and human rights
organizations track refugee movement. And of course, other satellites do things
like helping meteorologists predict the weather and making our phones and televisions work.
