Spatial Data and National Security

The following is a link to an article that I wrote a few years ago on matters a spatial data company might want to consider from a national security standpoint.

I wonder if the sentiments have changed in this environment (i.e. an even greater abundance of spatial data and applications)? http://www.imagingnotes.com/go/article_free.php?mp_id=21&Udo
