03 / Measure, annotate, export

Turn imagery into evidence

Measure an indicative distance, pin a note, or export your selected zone for a progress update.

Select Measure, then click points on the aerial image.—

Exports use the displayed image and are for visual reporting, not certified survey measurements. Notes save only to this browser unless exported.

Why this works

Both surveys are displayed against their own geographic coordinates. Your polygon, map centre and zoom are shared, so the selected work zone doesn't jump when dates change.

Indicative screen-based measurements only. No survey accuracy certification. Work zones and notes remain in this browser until exported. The demonstration imagery has been de-identified but the underlying geography may still be recognisable.
