Adopter Møn

Adopter Møn facilitates coordination between the Møn Biosphere forening and local volunteers. The platform enables community members to take responsibility for maintaining specific sections of the island's infrastructure.

Built to support ongoing conservation efforts, replacing manual coordination with a digital overview.

Creating an adoptable map required combining fragmented datasets from various government sources (roads, coastlines, forest paths).

I processed these sources into a unified geospatial network by cutting and planarizing the paths to ensure topological correctness. Each resulting segment was assigned a unique ID.

These processed geometries were then uploaded as a custom Mapbox tileset for rendering.

A corresponding dataset with matching IDs was stored in Supabase. When a user interacts with the map, the application retrieves the segment ID from the vector tile heavily optimising performance by avoiding complex spatial queries on every interaction.

The application provides a seamless interface for users to select and manage their adopted sections.

The client-side pathfinding engine (Dijkstra's algorithm) uses the underlying graph to snap user selections to the valid road network, ensuring that every adopted segment corresponds to a real-world asset.
