+# Running embeddings for Worldcover Sentinel-2 Composites
+This package is made to generate embeddings from the [ESA Worldcover](https://esa-worldcover.org/en/data-access)
+Sentinel-2 annual composites. The target region is all of the
+Contiguous United States.
+
+We ran this script for 2020 and 2021.
+
+## The algorithm
+
+The `run.py` script will run through a column of image chips of 512x512 pixels.
+Each run is a column that spans the Contiguous United States from north to
+south. For each chip in that column, embeddings are generated and stored
+together in one geoparquet file. These files are then uploaded to the
+`clay-worldcover-embeddings` bucket on S3.
+
+There are 1359 such columns to process in order to cover all of the Conus US.
+
+The embeddings are stored alongside with the bbox of the data chip used for
+generating the embedding. To visualize the underlying data or an embedding
+the WMS and WMTS endpoints provided by the ESA Worldcover project can be used.
+
+So the geoparquet files only have the following two columns
+
+|    embeddings    |   bbox   |
+|------------------|--------------|
+| [0.1, 0.4, ... ] | POLYGON(...) |
+| [0.2, 0.5, ... ] | POLYGON(...) |
+| [0.3, 0.6, ... ] | POLYGON(...) |
+
+## Exploring results
+
+The `embeddings_db.py` script provides a way to locally explore the embeddings.
+It will create a `lancedb` database and allow for search. The search results are
+visualizded by requesting the RGB image from the WMS endpoint for the bbox of
+each search result.
+
+## Running on Batch
+
+### Upload package to fetch and run bucket
+This snippet will create the zip package that is used for the fetch-and-run
+instance in our ECR registry.
+
+```bash
+# Add clay src and scripts to zip file
+zip -FSr batch-fetch-and-run-wc.zip src scripts -x *.pyc -x scripts/worldcover/wandb/**\*
+
+# Add run to home dir, so that fetch-and-run can see it.
+zip -uj batch-fetch-and-run-wc.zip scripts/worldcover/run.py
+
+# Upload fetch-and-run package to S3
+aws s3api put-object --bucket clay-fetch-and-run-packages --key "batch-fetch-and-run-wc.zip" --body "batch-fetch-and-run-wc.zip"
+```
+
+### Push array job
+This command will send the array job to AWS batch to run all of the
+1359 jobs to cover the US.
+
+```python
+import boto3
+
+batch = boto3.client("batch", region_name="us-east-1")
+year = 2020
+job = {
+    "jobName": f"worldcover-conus-{year}",

+        ],
+    },
