Tree Height & Field Measure

How tall is that tree — how far away, and how big is the plot? Field Measure Kit turns your phone into a digital clinometer and a three-in-one measuring tool: Height, Distance and Area, no tape to the top and no special gear, just your phone and a little trigonometry.

HEIGHT

Estimate the height of any tree, utility pole, flagpole or building. Stand back a known distance, sight the top and the base of your target, and the app combines the elevation angles with the distance to show a height in metres or feet.

• Two-point method — sight both the TOP and the BASE from one spot and enter the horizontal distance. Works even on sloping ground, because the base angle correctly adds its share. • Eye-height method — when the base sits level with your feet, sight only the TOP and add your own eye height. Faster, for flat ground.

DISTANCE

Flip the trigonometry around: enter a target's known height, sight its top (and base), and the app returns how far away it is. Handy when you can't walk a straight line to what you're measuring.

AREA

Measure a plot of land. Enter a rectangle's length and width, or the four sides and a diagonal of an irregular quadrilateral, and read the area in m², ft², acres or hectares. A built-in pacing helper turns your step count and stride into a side length, so you can size a yard, field or garden bed by walking it.

WHAT YOU GET

• Three modes — Height, Distance and Area in one app. • A live elevation-angle readout as you tilt the phone. • Capture top and base with a tap. • Zero-at-horizon calibration for a clean reading. • Pacing helper and multiple length and area units. • Metres or feet, your choice.

WHO IT'S FOR

Foresters and arborists, surveyors and landscapers, tree-care crews, students learning trigonometry, and anyone curious how tall the tree in the yard really is or how big the lot is.

A NOTE ON ACCURACY

Results are estimates. Accuracy depends on a correct distance or height, a steady phone and a clear line of sight — zero on a level horizon first. For estimation only; verify critical measurements with a calibrated instrument.
