+ # DynamicEarthNet-video: Daily PlanetFusion Image Cubes Compressed as Videos
29

+ ## Description
31
+
32
+
33
+ ### 📦 Dataset
34
+
35
+ DynamicEarthNet-video is a storage-efficient re-packaging of the original **DynamicEarthNet** collection.
36
+ The archive covers seventy-five 1024 × 1024 px regions (≈ 3 m GSD) across the globe, sampled daily from **1 January 2018 to 31 December 2019**. Each day is delivered as four-band PlanetFusion surface-reflectance images (B04 Red, B03 Green, B02 Blue, B8A Narrow-NIR). Monthly pixel-wise labels annotate seven land-cover classes: impervious, agriculture, forest, wetlands, bare soil, water and snow/ice.
37
+
38
+ All original GeoTIFF stacks (≈ 525 GB) are transcoded with **[xarrayvideo](https://github.com/IPL-UV/xarrayvideo)** to 12-bit H.265/HEVC, yielding dramatic size savings while preserving scientific fidelity:
39
+
40
+ | Version | Size | PSNR | Ratio |
41
+ | --------------------------- | ---------: | ------: | ----: |
42
+ | Raw GeoTIFF | 525 GB | — | 1 × |
43
+ | **DynamicEarthNet-video** | **8.5 GB** | 60.1 dB | 62 × |
44
+ | Extra-compressed (optional) | 2.1 GB | 54 dB | 249 × |
45
+
46
+ Extensive tests show that semantic change-segmentation scores obtained with U-TAE, U-ConvLSTM and 3D-UNet remain statistically unchanged (Δ mIoU ≤ 0.02 pp) when the compressed cubes replace the raw imagery.
47
+
48
+ The compact video format therefore removes I/O bottlenecks and enables:
49
+
50
+ * end-to-end training of sequence models directly from disk,
51
+ * rapid experimentation on 4-band daily time-series,
52
+ * efficient sharing of benchmarks for change detection and forecasting.

120
+
121
+ * **Semantic change detection** and **land-cover mapping** on daily 4-band sequences.
122
+ * Benchmarks include U-TAE, U-ConvLSTM, 3D-UNet (official splits A/B/C) .
123
+ * DynamicEarthNet-video can also serve for next-frame prediction and self-supervised representation learning on high-frequency optical data.

+ * **Summary**: Toker *et al.* introduce **DynamicEarthNet**, a benchmark of 75 daily 4-band PlanetFusion image cubes (3 m, 2018-2019) with monthly 7-class land-cover masks for semantic‐change segmentation. The paper establishes U-TAE, U-ConvLSTM and 3D-UNet baselines and proposes spatially blocked cross-validation to limit autocorrelation. ([arXiv][1])
