How to Draw Routes, Sectors, and Boundaries on iPhone

TL;DR

MGRS GPS lets you draw lines and polygons for routes, sectors, and boundaries, and plan multi-point routes that show distance and bearing for each leg — so a plan is laid out on the grid before you move.

Steps

In MGRS GPS, choose to draw on the map.
Draw lines for routes or polygons for sectors and boundaries.
For a route, place multiple points — each leg shows distance and bearing.
Keep them in a color-coded overlay for the mission.
Follow the plan with the navigation display.

Why it works this way

Planning on the grid beats improvising in the field. Lines let you lay out a route, polygons let you mark a sector or boundary, and per-leg distance and bearing turn a sketch into a real plan you can walk. Because shapes live in overlays, a plan for one operation stays separate from the next.

Tips & edge cases

Per-leg bearing and distance let you brief a route precisely.
Polygons are ideal for search sectors or restricted areas.
Group into an overlay so the whole plan toggles together.

FAQ

Can I plan a route with several stops? Yes. Plan multi-point routes, and MGRS GPS shows distance and bearing per leg.

Can I mark an area, not just a line? Yes. Draw polygons for sectors and boundaries alongside lines for routes.

Do routes and shapes stay organized? Yes. They live in overlays with your waypoints, so you can toggle them by task.
