OpenSearch rejects complex geometries (multipolygon). OS v2.19 #533
Description
OpenSearch rejects complex geometries that cross the antimeridian or pass near the pole.
I know this is primarily a database limitation, but I thought it would be worth sharing the observation because similar shapes or use cases may appear in other items.
When trying to ingest the following item:
https://pastebin.com/ALJYqsw6
(this is the corresponding cdse stac item: https://browser.stac.dataspace.copernicus.eu/collections/sentinel-3-sr-1-sra-a-stc/items/S3A_SR_1_SRA_A__20251117T153905_20251117T162935_20251119T075435_3029_132_382______PS1_O_ST_005) (it's pgstac)
I encountered the following error:
failed to parse field [geometry] of type [geo_shape]
At first, I suspected that the geometry simplification process might contain errors (near the pole or the date line). However, QGIS reports that the GeoJSON is valid. I also tried forcing a right-hand rule geometry and replacing the original one, but the error remained the same.
I then tried loading the item into pgSTAC — and it worked. I’m aware that OpenSearch is much stricter when ingesting shapes, and that PostGIS is far more advanced in this area, but collections like Sentinel-3 and Sentinel-5 contain complex geometries almost throughout. Because of that, we should either:
- develop shared documentation describing how such geometries should be processed, or
- adjust the OpenSearch mapping configuration to allow these geometries to be indexed.
Below is the mapping I used:
..."properties": {
"assets": {
"enabled": false,
"type": "object"
},
"bbox": {
"enabled": false,
"type": "object"
},
"collection": {
"type": "keyword"
},
"geometry": {
"type": "geo_shape"
},
...
}I also share the feature in a geojson format (for the ease of geometry revision):
