# Street-Level Imagery Dataset Metadata for street-level imagery across Eastern Europe and Northern Asia. Each record includes image URLs, coordinates, camera orientation, timestamps, and links to similar images captured at the same location over time. ## Summary | Statistic | Value | |-----------|-------| | Total Records | 934,191 | | Unique Images | 905,940 | | Unique Sources | 819 | | Time Span | 2016–2025 | | File Format | Parquet (Zstd) | | Compressed Size | 461 MB | ## Geographic Coverage | Boundary | Value | |----------|-------| | Minimum Longitude | 20.49° E | | Maximum Longitude | 152.32° E | | Minimum Latitude | 38.55° N | | Maximum Latitude | 69.05° N | Coverage spans urban centers and rural routes. Density is higher in populated areas. ## Camera Specifications **Directions** | Direction | Count | |-----------|-------| | Front | 740,079 | | Right | 194,112 | **Resolutions** | Preview Size | Full Size | Count | |--------------|-----------|-------| | 284×160 | 1920×1080 | 932,171 | | 90×160 | 1080×1920 | 1,886 | | 284×160 | 1536×864 | 77 | | 213×160 | 2016×1512 | 41 | ## Data Structure ### Fields | Field | Type | Description | |-------|------|-------------| | `id` | string | Unique image identifier | | `sourceId` | string | Source device or session identifier | | `heading` | float64 | Camera heading (0–360°) | | `cameraDirection` | string | Mount position (`front` or `right`) | | `timestamp` | string | ISO 8601 capture time | | `imagePreview` | struct | Thumbnail URL and dimensions | | `imageFull` | struct | Full resolution URL and dimensions | | `pos` | array | [longitude, latitude] | | `geometry` | struct | GeoJSON Point geometry | | `similar` | array | Related images at location | | `targetGeometry` | struct | Optional target reference | ### Image URL Schema Two resolution variants per entry: ```json { "imagePreview": { "url": "https://...", "width": 284, "height": 160 }, "imageFull": { "url": "https://...", "width": 1920, "height": 1080 } } ``` ### Temporal Links Records reference similar images from other timestamps at the same coordinates. Average of 14.3 links per location. ## Limitations Image URLs may [rot](https://en.wikipedia.org/wiki/Link_rot). Coverage concentrates in urban areas, and historical density varies by location. ## License Research use permitted. Comply with source terms of service and local data regulations.
