FieldGlass

Measure distance with camera + GPS — baseline triangulation. On this web preview — explore the HUD and the idea. Real measuring needs the phone app (sensors + permissions).

1. Try — Look for Help / Search (magnifier): type what you see, or ask what FieldGlass is.
2. Aim the X → MEASURE → walk, or tap SEARCH.

Phone — FieldGlass is on Google Play. Web = feeling; full measure = the phone app.
