The industry's total revenue estimate of $73 billion is shadowed by the effect of geospatial services, with an estimated $1.4 trillion in cost savings and driving $1.6 trillion in total revenue. Yep, with a "T".
To get these numbers, 1,000 business managers spanning US industry were surveyed. Over half (51%) claim they uses web-bassed mapping services in their business, and 40% "believe geo-services is an important component of the American competitive advantage."
Besides GIS being interesting, challenging, and at times fun, it sounds like a lot of people realize the importance of location.
