IMAGE TO MAP ALIGNMENT

To georeference a custom image on the map, follow these steps:

Import the image by tapping the “+” button on the image screen. You can upload any image (paper charts, harbor plans, bathymetric charts, or photos).
Select 3 points on the image: center the crosshair on identifiable landmarks and press Add Point.
Select the same 3 points on the map in the same order, then press Add Point again.
When both sets of 3 points are selected, the Affine button becomes active.
Press Affine to align the image as a map layer. It becomes zoomable and pannable like a native layer.

⚠️ You can press Reset anytime to clear all selected points and start again.

Why this is useful

Bring your own nautical charts or hand-drawn maps.
Use detailed local maps, construction layouts, or event plans.
Digitize any image and make it interactive and zoomable.
Combine official marine data with private or historical charts.

Once aligned, the image is tiled and saved like other map layers. You can use it offline with GPS and overlay waypoints or routes.
