y'know, survey marks. they're objects ranging from
- little rounded metal pegs with some numbers on them, to
- A STAR PICKET DRIVEN TO REFUSAL ENCASED IN CONC COLLAR, to
- just a tree lmao
if it's an object, and that object won't move (pawbs crossed), then you can take some accurate measurements of its position and elevation and call it a survey mark.
AND SO all of these are in a big database that gets updated as surveyors go back to previously installed marks, check if they're still there, and update the position and elevation if they want.
there's also a freeform text field.
here are some highlights from scrolling through... several thousand of these. emphasis mine, where present.

mark location is "very very very" approximate, and no faith whatsoever should be placed in its position, as when you see the CSS, there is nothing to locate it by except the shape of the road pattern!!!
Sketch was never drawn by installing surveyor - was originally a photo point in cleared area, Don't bother chasing surveyor or Comapany for sketch 13-7-05.

No longer suited to DNRM. Requires maintenance. Mark has always beeen solid and significant before it was noted as gone 08/08/2014. It will be very difficult to replace mark with one of similar quality. Before its demise, provided many years of good service to the profession and the public of Queensland. In the future, will be able to electronically lodge this form due to the dedicated work of the mark.
and a sad but sweet one to end on
