NGEE Seward Survey Notes
Revision as of 10:39, 3 June 2016 by 137.229.92.213 (talk)
- On the 4/21/2016 to 5/2/2016 trip RTK corrections were supplied from a point measured on the first trip that wasn't surveyed properly. So, make note if a transformation has been applied... perhaps I will include the points on this page or a link to the corrections.
- kind of wanted to get a placeholder here for things to forget about.
- I guess I can also add for the purposes of the second trip the base was treated as here in the original data:
Point ID Northing Easting Height tlrbcp02 7178309.855 454856.459 83.358
- Running raw gps data through Opus results in the site moving to:
Point ID Northing Easting Height tlrbcp02--OPUS 7178293.021 454866.017 75.523
- On the first trip there were three bases (at the moment positions listed here are uncorrected from OPUS :
Point ID Northing Easting Height telsnw2 7178275.291 455045.841 85.667 [Initial base... dug down 1m or so into a snow drift... not suitable for permanent] nrtel8bs 7180048.627 454031.405 261.143 [Top line base... turns out could only access the GP1-2 line, GP7-11 line, and most of the GP17-21 line] ... moved base to tlrbcp01 after telemetry problems tlrbcp01 7178216.425 454700.166 88.422 [Located on the bottom of watershed, 3 foot screed stake in ground here], used after base repositioned to bottom of hill for Bob, Cathy, and Lily measurements
