Limitations

Current Limitations (v0.1.x)

This page summarizes user-facing limitations in the current implementation.

1) Spatial input CRS

• BBox and PointBuffer currently require crs="EPSG:4326".
• Other CRS inputs are not accepted at the API boundary.

2) Temporal behavior for on-the-fly models

• Most on-the-fly adapters treat TemporalSpec.range(start, end) as a window filter and build one composite image (median by default).
• This is not an automatic single-scene selection by acquisition date.

3) Temporal constraints are model-specific

• gse currently requires TemporalSpec.year(...).
• copernicus currently supports only year 2021.
• Some precomputed models may ignore finer temporal granularity.

4) Grid output is not always georeferenced raster space

• For ViT-like models, OutputSpec.grid() is often a token/patch grid (D, H, W).
• Treat it as model-internal spatial structure, not as guaranteed geo-aligned pixel coordinates.

5) Optional dependency surface is large

• Different models/providers require extra packages (earthengine-api, torch, rshf, torchgeo, etc.).
• Missing optional dependencies will fail at runtime for the corresponding model path.

6) Known edge case: tessera tile boundary mosaic

• Near some UTM-zone boundaries, fetched tiles may have different CRS/resolution and strict mosaic can fail.
• If this occurs, try shifting ROI slightly or using a smaller ROI/window.
