[lojban] surveying terms



I thought of this sentence for la jufra karni:

mi zvati la .uagnr. gi'e farcta la mkydauyl. gi'e mrecta re le clupa mokca 
tezu'e lenu farcarna le cartu

This is intended to mean "I occupied Wagner, backsighted McDowell, and 
foresighted two of the traverse points in order to orient the map." (I and 
another member of the crew did that yesterday.) I'm not at all sure about the 
technical terms, though:

{zvati} for "occupy" seems reasonable. I was there, and if I wanted to be any 
more specific I'd have to say that I set up an instrument over the point.

"backsight" means to point the instrument at some point and set the angle or 
elevation (angle in this case; we're not measuring elevations) to some 
assumed value (usually 0 for angles) or to its value if known. In this case 
the bearing from Wagner to McDowell is known, but we didn't have it, so we 
set it to 0. The prof is going to bring in a sheet with coordinates of these 
points.

{mrecta} seems reasonable. I looked at the points and wrote the measured angle 
and distance.

A traverse is a sequence of points with the distances and angles between them 
measured. This traverse is closed, so it is a clupa, but I don't think that's 
the best term.

Is {mokca} the right term for a location which has zero extent in X and Y, but 
does have duration? The traverse points are pieces of wood stuck in the 
ground with brads driven into them; we'll pull them up when we're finished 
using them.
