PanoramaOSM: Open World Viewer

PanoramaOSM was part of a family of 'PhotoPanorama' applications designed to visualize geotagged content on mobile maps. While other versions relied on Yandex MapKit or Google Maps v1, this project focused on the open-source ecosystem using OpenStreetMap and the osmdroid library.

The app handled clustering of thousands of photo markers, asynchronous image loading, and map caching. Although the primary data source (Panoramio) was shut down by Google in 2016, the project remains a valuable reference for implementing custom map overlays and working with legacy mapping SDKs. I have recently restored the source code and documented a path to switch the data source to Wikimedia Commons API.
