OwnHomeMap turns available map data into wall art through a bounded rendering pipeline. The selected place is converted to coordinates, then the active map source supplies features for the requested area. When automatic mode is configured, OpenFreeMap/OpenMapTiles supplies source-classified vector features; if that path fails, direct OpenStreetMap/Overpass supplies supported tags. The parser normalizes roads into stable visual classes, while water and park polygons remain separate layers. Coordinates are fitted to the poster canvas, not used to create a navigation map. The selected theme assigns colors; fixed internal road types determine relative line widths. Typography and optional layout effects are then placed above the cartographic layers. The preview uses the same composition rules as the purchased design, with a protective watermark on the preview only. A source feature can appear only when it is returned for the selected area and matches the renderer's supported classes. The result is therefore a designed snapshot of available data, not an independent survey of the place.
Pipeline at a glance
- Input
- A selected place, center point, and viewing radius.
- Data
- Available roads, water polygons, and selected green-space polygons.
- Transform
- Tag classification, canvas fitting, theme styling, and typography.
- Output
- A decorative map composition rather than a navigation product.
The five processing stages
1. Locate
Resolve the chosen place to a center coordinate and requested extent.
2. Request
Load the supported features available from the configured source for that area.
3. Classify
Group roads by supported highway tags and keep water and green-space polygons separate.
4. Compose
Fit coordinates to the canvas, draw ordered layers, and apply the chosen theme.
5. Personalize
Place the title, subtitle, coordinates, and optional message above the map.
Limits to keep in mind
- The output reflects features returned by the active source at render time; it does not verify them against a land survey.
- Unsupported tags, buildings, businesses, transit lines, and many points of interest are intentionally outside this poster pipeline.
- The poster is decorative and must not be used for routing, emergency response, property boundaries, or measurement.
