Started a survey today (our first!) using the multistation. Here are lots of notes as a memory dump of what I did:
- Didn't orient the multistation (MS). Assuming that we (I) will be able to stitch together "scenes" from duplicate shoots of the same target from the different MS positions.
- I <think> the MS height is set to the default 1.5m, even though I didn't control the physical position to be at this height.
- All targets were shot with a height of 0m
- Project "SAVANT" was used in internal memory on the theodolite. Hopefully, I can access it somehow!
- most targets were round (sphere/cylinder) and should have the position adjusted by the target radius in the direction away from the theodolite
- probably should have shot the boom arm of the 2D sonics to get more accuracy on azimuth, but didn't.
- Here is my attempt at a naming convention for points, not always followed
- first character of i, r, u, l for the 4 towers, p for power line, full names of other objects.
- when needed, also A for aux1, B for aux2
- second character t for TRH, s for sonic, top for top of tower, base for base, etc.
- third character 0 for 0.2m, 1 for 1.5m, 3 for 3m, 4 for 4.5m, 6 for 6m, 8 for 8.5m, a for 10m, f for 15m, aa for 20m (don't ask me why)
- fourth character t for top, b for bottom, l for left (arbitrary), r for right or rear, f for front
- fifth character numeric for scan sequence if multiple scans (from multiple positions and/or if an alternate scan for that position was used
- first character of i, r, u, l for the 4 towers, p for power line, full names of other objects.
- Started near init, from here scanned:
- used my cell phone to determine the MS position as: 40.211578, -88.410728, 79.7m (not right), 4.00m
- 3 corners of sodar clutter wall, at the base of where it goes vertical, used s, e, n for the cardinal direction the corner was pointing
- the center of the luft's radome
- init's tower base
- trhs at the top/center of the inlet tube
- (I'm not sure that I had an "i" as the first character of all of these targets.)
- 2D sonic along the viewable side of the transducer, mid-height
- 3D sonics at the center of the two transducer spheres, a point as far forward as I could shoot on the boom, and a point on the boom just forward of the mounting clamp, meant to be similar to those done in Perdigao.
- square booms were shot about 1mm below the top of the boom, at both the front and back. Later scans, I remembered to come forward a bit on the back scans to avoid the milled-down part of the boom.
- I think I inadvertently used "b" for both bottom and back of the 1.5m CSAT, so this point may have been overwritten, since I also wasn't using sequence numbers yet.
- power poles near uconv (I defined as Pg & Pf), scanned from the point on the upper cross-beam where the insulator hangs down
- top mounting bump on rel
- Moved to rel, and scanned:
- cell phone said MS position was: 40.211796, -88.407181, 216m, 4.00m
- top TRH on init
- point at which spline ball arm met tower top plate on uconv
- I think I also did just the top of the north tower member on uconv
- top TRH on uconv
- base of splines on spline ball on lconv
- top TRH on lconv
- (couldn't see the power lines)
- (couldn't see the same bump on the top of rel, but shot the hole in the top plate underneath it)
- TRHs on rel and auxes
- 2D on rel
- 3Ds on rel and auxes
- note that CSAT.aux2 is a CSAT3 with my strange mounting block adaptor. I scanned the outside of the block (like the other CSATs) with a "0" suffix and the nearest points on the round boom with a "2" suffix. The "1" suffix was where Hendrik noted that the laser seemed to see both round and square, even though the crosshairs were just on the round.
- Ran out of time, and threat of rain, before getting to uconv and lconv.
- Didn't scan the fiber optic mounting points yet.
- Intended to shoot the lidar trailers/tent, but didn't yet.
