Project Components

Tile Loader

The tile loader is implemented in Go and is located in example/load_cache/main.go. It loads OSM tiles for a specified bounding box and zoom levels, and caches them in Redis.

OSM Tile Server

The OSM Tile Server is implemented in Go and is located in src/osm_tile_server/main.go. It serves OSM tiles from Redis or fetches them from the OSM servers if they are not cached.

OSM Map Viewer

The OSM Map Viewer is implemented in Python using PySide6 and is located in src/osm_graphics_view.py and src/mainwindow.py. It provides a graphical interface for viewing and interacting with OSM maps.

Search Widget

The search widget is implemented in Python and is located in src/searchwidget.py. It allows users to search for locations using the Nominatim API and displays suggestions in a list.
