Trekker is Google’s all-in-one backpack that features a 360° camera array (to create stunning panoramic images), two positioning LIDARS (for mapping terrains), a computer (with heat sink cooling), and two hot swap batteries. It works with Street View, Google Maps, and Google Earth to produce interactive maps of places vehicles cannot access, such as wilderness trails, caves, museums, and dense city centers. It is waterproof, durable, and comfortable for extended wear time. Trekker is a valuable educational tool that has created a subculture of travelers committed to revealing new frontiers.
