OpenClimbing 2.0 moves climbing route data into OpenStreetMap and Wikimedia Commons

OpenClimbing 2.0 changes how climbing route data is stored and maintained. Instead of keeping contributions in a private database, the application writes route information to OpenStreetMap using community schemas and publishes imagery to Wikimedia Commons. This means the data remains available even if the application itself disappears. The trade-off is that the project now depends on external infrastructure and community-maintained schemas rather than controlling its own storage layer.

The application adds climbing-specific features that generic mapping tools lack. It can display areas, crags and routes, convert between grading systems, filter sectors and draw climbing lines directly on photographs. Version 2.0 also adds a logbook for recording ascents and viewing statistics. These features demonstrate how a domain-specific interface can provide value on top of shared data without locking the underlying information into a silo.

Offline functionality is a core requirement rather than an afterthought. The application can export areas or crags as PDF guides containing maps, routes, grades and route lines over photographs. This matches the real-world conditions where climbers need information - areas with poor or no mobile reception. The PDF export shows how offline-first design can be essential for field tools operating in remote environments.

The project illustrates the difference between open data and useful data. While the underlying information is stored in open infrastructure, it still requires maintenance to remain accurate. Someone must map routes, confirm positions, choose appropriate OSM relationships and correct mistakes. The reported 40,000 routes don't guarantee completeness or local verification. The architecture enables community correction but doesn't eliminate the need for ongoing maintenance.
