How accurate do you need to get? Is this an object you need to return to or a building? 20ft accuracy is plenty fine for most uses. If we had an idea of *what* you were trying to do we could probably help you better.
Not as an attempt to drive traffic to our forums, but the GPS Units & Software forum is filled with experienced GPS folks. You could get a decent response from these guys if you outlined your need more. http://forums.groundspeak.com/GC/index.php?showforum=11 Jeremy -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ian | Urban Mapping Sent: Thursday, March 23, 2006 5:41 PM To: [email protected] Subject: [Geowanking] GPS Receivers Right--that's what I meant... I'm thinking that if I can get post process out of a gps, why pay for accuracy in the device? I don't need real-time processing as I'm collecting a lot of point data in urban areas (which compounds the real time problem). The more I think about it, the less sense it makes to purchase an expensive device if it's possible to get the data out in a dgps-able format, as it can always be 'fixed in the mix.' Thoughts? ian You can't post-process NMEA. You need RINEX, which you can sorta get out of an eTrex using the Async program: http://artico.lma.fi.upm.es/numerico/miembros/antonio/async/ Or are you looking for one to do real-time DGPS with a RTCM beacon? Or better yet, what's your budget and what kind of accuracy are you willing to pay for?

It's the cheapest unit that still has a cable connector. You'll have to purchase the cable separately.

I went to a great GPS workshop in NYC this week and now know just enough to be dangerous... Does anybody know what is the lowest price GPS device with NMEA (to allow for post DGPS)? thanks Ian White :: Urban Mapping LLC :: [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> 120 West 45th Street 20th Floor :: New York NY 10036 Tel.212.242.8267 :: Fax.866.385.8266 :: www.urbanmapping.com Marc Pfister Geospatial Data Manager ENPLAN [EMAIL PROTECTED] 530/221-0440 x108 530/221-6963 Fax -------------- next part -------------- An HTML attachment was scrubbed...
