From 1daa0ed8e99e2b15fcaa1a1801b4ec5f383e573b Mon Sep 17 00:00:00 2001 From: Wietze Date: Thu, 9 Oct 2025 22:02:44 -0400 Subject: [PATCH 01/16] docs: add interactive notebooks for GeoZarr exploration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three Jupyter notebooks demonstrating GeoZarr data access and pyramid features: 01_quickstart.ipynb - Load GeoZarr from S3 with embedded STAC metadata - Visualize RGB composites - Inspect geospatial properties 02_pyramid_performance.ipynb - Benchmark tile serving with/without pyramids - Measure observed 3-5Γ— speedup at zoom 6-10 - Calculate storage tradeoffs (33% overhead) 03_multi_resolution.ipynb - Access individual pyramid levels (0-3) - Compare sizes (4.7MB β†’ 72KB reduction) - Explore quality vs size tradeoffs These notebooks help users understand the pipeline outputs and evaluate pyramid benefits for their use cases. Still evolving as we refine the conversion process and gather production feedback. --- notebooks/01_quickstart.ipynb | 337 ++++++++++++++++ notebooks/02_pyramid_performance.ipynb | 513 +++++++++++++++++++++++++ notebooks/03_multi_resolution.ipynb | 402 +++++++++++++++++++ notebooks/README.md | 90 +++++ 4 files changed, 1342 insertions(+) create mode 100644 notebooks/01_quickstart.ipynb create mode 100644 notebooks/02_pyramid_performance.ipynb create mode 100644 notebooks/03_multi_resolution.ipynb create mode 100644 notebooks/README.md diff --git a/notebooks/01_quickstart.ipynb b/notebooks/01_quickstart.ipynb new file mode 100644 index 0000000..455c277 --- /dev/null +++ b/notebooks/01_quickstart.ipynb @@ -0,0 +1,337 @@ +{ + "cells": [ + { + "cell_type": "markdown", + "id": "e80abebf", + "metadata": {}, + "source": [ + "# GeoZarr Quickstart: S3 Access & RGB Visualization\n", + "\n", + "**Load cloud-optimized GeoZarr from S3, inspect embedded metadata, create RGB composites.**\n", + "\n", + "**Setup:** `uv sync --extra notebooks` + AWS credentials \n", + "**Dataset:** Sentinel-2 L2A tile (10m bands), pyramids 0-4, STAC-embedded" + ] + }, + { + "cell_type": "markdown", + "id": "57b5bc03", + "metadata": {}, + "source": [ + "## 1.

Script is now included in Docker image, eliminating need for runtime pip installs and curl downloads. Changes: - Add scripts/publish_amqp.py with routing key templates and retry - Update workflows/amqp-publish-once.yaml to use pre-built image - Add workflows/ directory to docker/Dockerfile - Add

"tile_width": 512 -} -``` - -**Key Differences from S2**: -- Groups: `/measurements` (S1) vs `/measurements/reflectance/r10m` (S2) -- Chunk size: 2048 (S1) vs 4096 (S2) -- GCP handling: Explicit `--gcp-group` flag required for S1 -- Memory: 16GB limit (vs 12GB for S2) - ---- - -## Known Issues & Observations - -### Successful Workarounds -1. βœ… **AMQP Connection**: Fixed by using correct service name (`rabbitmq.core.svc.cluster.local`) -2. βœ… **Sensor Event Binding**: Fixed by matching event names (`rabbitmq-geozarr/geozarr-events`) -3. βœ… **Secret Name**: Used `rabbitmq-credentials` (not `rabbitmq-secret`) - -### Performance Notes -- Conversion took ~20 minutes for 30k x 15k resolution S1 GRD -- Metadata group processing added ~5 minutes -- Multiscale pyramid generation efficient (using level N-1 as source) - -### Preview Generation -- TiTiler successfully generated XYZ tiles for VH polarization -- Rescaling: 0-219 (typical for S1 GRD amplitude) -- Variable path: `/S01SIWGRD_20251007T052723_0025_A350_A991_07A653_VH/measurements:grd` - ---- - -## Conclusions - -### βœ… Validation Complete -- S1 GRD data successfully converted to GeoZarr format -- Multiscale pyramids generated (6 levels) for both polarizations -- STAC item registered with all required assets and preview links -- Preview generation working via TiTiler -- All metadata groups preserved in output - -### βœ… UI Enhancements Successful -- Argo UI now shows full workflow parameters upfront -- Step-by-step progress clearly visible -- Better context during long-running operations -- Easier debugging with labeled workflows - -### 🎯 Production Ready -The S1 GRD pipeline is ready for production use with: -- Automated AMQP-triggered workflows -- Proper error handling and validation -- S3 output with correct structure -- STAC API integration complete -- Preview/visualization support - ---- - -## Next Steps - -1. **Apply to Production Namespace**: Deploy enhanced workflow template to production -2. **Monitor at Scale**: Run on larger S1 dataset (multiple tiles) -3. **Performance Tuning**: Evaluate Dask parallelization effectiveness -4. **Documentation**: Update user guide with S1-specific examples -5. **Collection Registry**: Add more S1 collections (EW, IW, etc.) - ---- - -## Files Modified - -### Workflow Configuration -- `workflows/template.yaml`: Enhanced UI visibility, parameter display step -- `workflows/sensor.yaml`: Fixed event source binding -- `workflows/amqp-publish-s1-e2e.yaml`: S1 E2E test job (NEW) -
