many of the software packages have these geoid models within them. I use foresight and it has the Geode models. I understand we have a new one now Geoid 06

Go to http://landsurveyorsunited.ning.com/profile/PhilStevenson and see if he can help us figure this out. He or someone he knows can surely help us. keep me in the loop and let me know your progress.

Thank you Gary, do we have other software to process it instead of GNSS Solutions, i cannot find the LPT key of my software so the program dont open as expected. hmmmn, i really need a geoid model for saudi arabia to refine my elevations. God blessings to you and rest of family...

The Geoid thing is one on those things that I do once in a great while and forget about it till something goes wrong or that I configure a new setup. I found some notes that indicate that one can obtain the files from http://www.ngs.noaa.gov/PC_PROD/GEOID03/ and determine the area by map or by region. You may have to pick from choices bracketed byh Lat/Lon from that site listings. Then use your GNSS Solutions - Tools -Geoids to open them. I just checked it and I already had a bunch of geoid files that may have been included with the GNSS program so I can extract an area out of it to keep the size down. I recall that I transferred it onto my SD card and then made sure it was selected when I used fast survey or the survey functions. I am a little foggy on it and I will have to play with it again to do it.

I will plan to look for that. If all else fails, I call my buddy Phil Stevenson with Magellan Pro.

hey brothers, where can i download fastsurvey (thales zmax) geoid separation files (gsf geoid model) for Saudi Arabia

looks good Marvin i have great results as well. I think many who don't are ether not certain of configuration of the components they use or they are using the wrong datum or region setup. i equally get grand results. I setup control for a surveyor with the trimble R8 and he found that i was within a 1/16 of inch as the design elevations he had generated.

I use Thales ProMark 3 on every job, process my own data against CORS sites in my state, and have had very good results. Have checked on job site and have found the GPS to stay within the +/- 0.03' with good setup and location.

Hi Gary, agreed. If you look after the simple detail, the bigger things usually falls in place. Rod bubbles....what method do you use to check the adjustment of your rod bubbles?
Reply by Jim on November 16, 2009 at 11:21am
sounds like you are my kind of guy Gary. Simple is good. I use the GPS for most all of my setups. How long are sitting on a point to get it down to digestable readings?
