I know that sensors are not a typical subject for columns in POB, but there are some big things happening with sensor technology that will directly impact everyone who uses geospatial imagery and data for aerial surveying and mapping.

As unmanned aerial systems (UAS) become more prevalent in the skies, the United States is engaged in spirited conversation about their impact on the constitutional guarantees of privacy and free speech. Over the next 10 years, tens of thousands of these vehicles could be safely darting in our national airspace, providing a wealth of valuable services to homeowners, ranchers, farmers, journalists and businesses.

This technological leap forward brings with it challenges to our concept of “privacy” and “free speech” our society has not yet faced.
