Perhaps there is a lesson here, if not a solution to the issue of a professional organization for geomatics professionals here in the U.S. and worldwide for that matter. RICS, the Royal Institution of Chartered Surveyors, was founded in London in 1868.
Today RICS has more than 100,000 members globally, with the majority of the net membership growth coming from outside of the UK. They work closely with professional organisations around the globe and have a network of offices reaching across the world’s major and emerging economies.
Is this the organization that geomatics professionals in the U.S. have been searching for? You have to certainly be impressed with their organization, at least on the surface.
As an example of one of their work products have a look at these Geomatics Client Guides. A valuable resource.
