Tracking Changes in Images

DSC_0552Many today take photos from all angles and perspectives. They then catalog, store or publish them for others to see. But many would also like to know if anything changes in those images as time passes. We may set up an automated system to take a particular view everyday, week or month. Perhaps even a shorter interval or longer. But what we want to know is is there is a change.

I’ve always tried to go to locations where things happened after weather events or new structures have gone up or are going up on Google maps. These may be as large as football stadiums going up to as small as a neighbor’s pool. In either case I am the one that has to determine if there is a change. Now there is a method for automizing that.

The folks at Hexagon GeoSpatial have done this. It came about largely from the need of changing home landscapes as property values are determined from additions. More information on the actual steps are in this article. I just like the fact that more is being automated.
