The Earth has been orbited by many picture taking satellites for several decades now. Many of these images of the earth surface are regularly updated, every other week in many cases, and thus there is no better way of measuring change and observing these changes from our eyes in the sky. High up in the sky. Not only have they been around for decades, but recent progress has resulted in more detailed images being made available, and some of the best news relating to these is that in some cases they come at no cost. Able thus to frequently assess and determine change across landscapes is a fine offering.
Albeit not necessarily within each what3word, - which is possible at a cost – our work on projects making up several of these addresses can still be monitored through this first line of observation from the sky.
