Miller - You might have pretty good coverage in Belize. The Federal Aviation Administration (FAA) has a web site describing WAAS and coverage:
http://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/waas/ The current extent of coverage (in real-time!) is provided here: http://www.nstb.tc.faa.gov/RT_VerticalProtectionLevel.htm If these links don't come through, just google "WAAS FAA" Best, Tim Howard >>> Miller Scott <[EMAIL PROTECTED]> 12/2/2008 12:49 PM >>> I have a quick question about GPS/GIS work in Central America. First, can WAAS-enabled units be expected to have the reading correction outside of the continental states? Is there a database/map showing where WAAS should work? Assuming, WAAS does not work in coastal Belize, what would you recommend for affordable units ($<200), and what kind of accuracy (in meters, preferably) could be expected? If someone with some expertise in the area has some info on these issues, I would greatly appreciate an e-mailed response to [EMAIL PROTECTED] Thanks in advance, Miller
