NGEE Seward Survey Notes

• 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

       1 ) export points from trimble biz center as csv
       2 ) organize points for layout & naming convention as is done in google sheet
       3 ) convert geopdf to geotiff in arc
       4 ) Compare OPUS position to position used in snow melt survey
       5 ) compute difference
       6 ) apply difference to points using rtk for snow melt survey (just x & y for now)
       7 )

Adjust a point using output from OPUS: http://geoline.com/wp-content/uploads/2014/01/TechTalk_TBC_Workflow_OPUS_.xml-files.pdf

• Could we use the XYZ data to better constrain the creek position?
