Google gave the world a gift yesterday with the release of the global timelapse viewer that aggregates Landsat imagery from 1984 through 2012. While this effort isn’t unique, it is high-profile with its exclusive media alliance with TIME magazine, and it simultaneously illustrates the impact of humans while also showing the difficulty of aggregating our knowledge about global change.

The legacy of film imagery spans just 150 years, although it still continues to some degree today, from its start at the dawn of photography in the mid-1800s to its continued use on Russian reconnaissance satellites. With the advent of commercial large-format digital aerial cameras in the early 2000’s, in a very short time film has been replaced by digital sensors for mapping applications, and with it many barriers to wider use of aerial and satellite imaging and monitoring have fallen away.

Today is the 43rd Earth Day, providing an important touchpoint of our planet’s health. The widespread and non-partisan embrace of the very first fight against environmental pollution has been sustained and has become a yearly global gathering where individuals become educated to decrease their impact on the Earth, and where we all are called to action to protect our planet.

Last week, the Obama administration announced a plan to invest $100 million to begin mapping the brain. While much of this work is ongoing in many disciplines, the Brain Research through Advancing Innovative Neurotechnologies or BRAIN Initiative has been touted as an investment in basic scientific research for greater understanding and better public health with job creation and economic returns. The Human Genome Project to map all human DNA is reported to have returned $140 for every dollar invested, and similar returns are hoped for in this effort.

Remote sensing has its foundation in observations that provide unique viewpoints to enable greater insight. The data explosion that is taking place in earth observation, with new satellites launched around the world on a monthly basis, along with new unmanned aerial platforms, promise to usher in a whole new level of understanding of Earth and its systems. Increasingly the sensors that are onboard these platforms provide a span of spectral wavelengths that provide details beyond what can be seen with the human eye.
