marine / terrestrial / biome field issues #715

Open peggynewman opened 2 years ago

This is carried over from previous issue in the ALA repo: https://github.com/AtlasOfLivingAustralia/la-pipelines/issues/464

OBIS has raised this again. It's important for them to be able to query marine occurrences.

There is an accuracy problem with biome lookups particularly with marine coordinates close to a coast. Example records:

https://biocache.ala.org.au/occurrences/7681cd33-1154-44cf-9063-03a39d2df349 https://biocache.ala.org.au/occurrences/71996a3f-60bc-4f34-b1cb-63f615503610 https://biocache-databox.ala.org.au/occurrences/4b065b9f-539d-47ba-bf4b-944cd84c2254

Suggestion in the previous issue was to use shapefile intersects over the GADM lookup.

@djtfmartin Does the biome impact the way sampling is represented as well? ie this marine biome record displays a bunch of marine layers (eg chlorophyll, bathymetry), whereas this marine record labelled as terrestrial biome displays terrestrial layers (eg. tillage)

BIOME uses a bitmap to provide a faster search, instead of doing spatial query, but the result could be not accurate when the coordinate is very close to boundary

Another marine record appearing as TERRESTRIAL in the biome field. https://biocache-test.ala.org.au/occurrences/1fe09d56-bfca-4710-a842-07369490e619

Would be great if we could fix this.
