D draw · click to place corners · click the first corner, double-click or Enter to close · Backspace removes the last corner · Esc stops.
M measure · click points to measure a distance; click the first point to close it and get an area · double-click or Enter ends a line · Elevation shows the ground profile along it.
Lock a paddock with the padlock on its card: its corners can't be moved or deleted, and it can't be deleted or cleared until unlocked. Names and colours stay editable. Ctrl+Z undo · Ctrl+Y redo.
S straighten · click a fence to use as the reference, then click other fences to give them the same bearing (or the exact opposite). The end nearer the reference stays put and the other corner moves the shortest distance onto the new line.
L match length · click a fence to use as the reference, then hover another fence near the corner you want to move (a ring marks it) and click; that corner slides along the fence, keeping its bearing, until the fence is the same length.
Z zooms to all visible paddocks. The eye on a paddock's card hides it on the map (it still counts in totals and exports).
Magnetic bearings use the World Magnetic Model (WMM 2025) for today's date, with one declination for the whole map so parallel fences read the same.
E edit · drag a corner to move it (shared corners move together) · drag a small midpoint dot to add a corner · right-click or Delete removes a corner · hold Alt while dragging to separate a shared corner from the selected paddock.
Elevation profiles use SRTM 30 m satellite elevation data (Open Topo Data), falling back to Copernicus 90 m (Open-Meteo). They show the lie of the land well, but individual heights can be out by a few metres, so they are for planning, not survey levels.
Lengths and bearings are on the WGS84 ellipsoid (Vincenty), bearings are true. MGA coordinates use GRS80; GDA2020 and WGS84 positions agree to within about 1–2 m, which is less than typical imagery error.
