NGS DataBase for control

[Z15]

If you want to see latest info try these NGS sites

 

If you know the station name http://www.ngs.noaa.gov/cgi-bin/ds_desig.prl

 

The PID http://www.ngs.noaa.gov/cgi-bin/ds_pid.prl

 

Search an area http://www.ngs.noaa.gov/cgi-bin/ds_mm.prl

 

I notice the db here is not up to date and you may save some time and energy checking with NGS

you could just go here. The map search is kind of nice.

The primary advantage of consulting the NGS data sheets is that many of their bench marks are sited to plus or minus six seconds, and are merely interpolated off an map. These measurements are referred to as "scaled." Their import to us is that they resolve to a measurement with something like a 1200 foot diameter circle of confusion. Bundy's description invariably lists these to three decimal places of minutes, implying a resolution of six feet. If you're searching for a bench mark under a 60-year deposit of forest humus, you're in for a long day without a tape measure and compass.

 

The indicator we are interested in on the NGS data sheet is the horizontal coordinate. If that line ends with 'scaled', we are looking at a very rough indicator. If the mark's horizontal measurement is 'adjusted' it is a much more precise location and it will be sited and cited to five something lilke decimals of seconds -- a wonderful calibration point for playing with our gpsr.

 

good luck! . . . . patrick
