According to a recent article in the science journal Nature. the employment market for people trained in geospatial technologies will grow dramatically over the next several years. This appears to be true both in the U.S. as well as Europe. (Nature is published in the United Kingdom).
The article reports that US Department of Labor recently identified geotechnology as one of the three most important emerging and evolving fields, along with nanotechnology and biotechnology. Another tidbit is that the the National Imagery and Mapping Agency (actually renamed recently the National Geospatial-Intelligence Agency) alone will require 7000 new trained staff in the next three years.
