Questions about the Bearings poster

What’s on the Bearings poster?

A bearing is a direction measured clockwise from north, and a back bearing differs fr…; Back bearing = forward bearing ± 180°; Bearing 040° = Back bearing 220°; Bearing 250° = Back bearing 070°; Next leg forward = Back bearing + angle; Common mistake: Mixing grid, true and magnetic north → State which north you mean. Educational reference. Grid convergence and magnetic declination are published values that change with place and date.
Who is the Bearings poster for?
Bearings belongs to the Civil Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning surveying can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Bearings poster?
Reading a traverse sheet, or converting between plan and compass. A wall chart earns its place by being glanceable from where the work is happening, so Bearings belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
What other posters go with Bearings?
Areas & Volumes, Contours and Setting Out a Curve sit alongside Bearings in the Civil Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Areas & VolumesContoursSetting Out a Curve
Is the Bearings poster free to download and print?
Yes. Bearings downloads as a free PDF with no account, no email and no watermark, like everything else in the Civil Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Bearings poster print at?
Bearings is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Bearings loses nothing.Printing guide
