+# DynamicEarthNet-video: Daily PlanetFusion Image Cubes Compressed as Videos
+
+## Description
+
+
+### 📦 Dataset
+
+DynamicEarthNet-video is a storage-efficient re-packaging of the original **DynamicEarthNet** collection.
+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.
+
+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:
+
+| Version                     |       Size |    PSNR | Ratio |
+| --------------------------- | ---------: | ------: | ----: |
+| Raw GeoTIFF                 |     525 GB |       — |   1 × |
+| **DynamicEarthNet-video**   | **8.5 GB** | 60.1 dB |  62 × |
+| Extra-compressed (optional) |     2.1 GB |   54 dB | 249 × |
+
+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.
+
+The compact video format therefore removes I/O bottlenecks and enables:
+
+* end-to-end training of sequence models directly from disk,
+* rapid experimentation on 4-band daily time-series,
+* efficient sharing of benchmarks for change detection and forecasting.

+* **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])
