jiayuasu opened a new issue, #2804: URL: https://github.com/apache/sedona/issues/2804
## Background Follow-up from #2769. The structural reorganization of raster docs (removing Raster-loader.md / Raster-writer.md, creating per-function pages, updating the tutorial to lead with the `raster` data source) is addressed in #2802. This issue covers the remaining ask: the raster tutorial should use a **running example** that tells an end-to-end story, with **more visuals** at each step. ## Proposed changes Rewrite `docs/tutorial/raster.md` to follow a single dataset through the full workflow: 1. **Load** a GeoTiff using the `raster` data source 2. **Inspect** metadata (RS_MetaData, RS_Width, RS_Height, RS_GeoReference) 3. **Visualize** the raw raster (RS_AsImage screenshot) 4. **Process** — e.g., clip to a region, resample, or compute NDVI via map algebra 5. **Visualize** the processed result 6. **Save** to disk using the raster writer Each major step should include a visual (screenshot or rendered image) so readers can see what the raster looks like at that point in the pipeline. ## Notes - The tutorial currently has isolated code snippets that don't share a common dataset - Existing images in `docs/image/` (DisplayImage.png, rasterized-image.png) can be reused where appropriate - Multi-language tabs (Scala/Java/Python) should be preserved for key steps, but Python can be the primary language for the narrative -- This is an automated message from the Apache Git Service.
