+### Drosophila Use Case: Occurrence Cube
+
+[Corresponding data request issue](issues/86): [GBIF data](https://www.gbif.org/dataset/search?q=) are requested through [this data-request](issues/71). Our sister project B-Cubed, with GBIF as partner, will provide selected data. 
+
+#### Datacube Structure
+
+- Domain dimensions:
+ -   Lat, Long:
+  -   Extent (RD - EPSG:28992): Xmin: 168280, Xmax: 223880, Ymin: 512055, Ymax: 535555
+  -   Extent (lat/lon): Xmin: 5.5831989141242966, Xmax: 6.4086515407429623, Ymin: 52.5917375949509562, Ymax: 52.8070852699905871
+  -   Resolution: 10m
+ -   Time (year): 2018
+ -   Taxon: 7-digit taxon id, categorial
+- Range type:
+ -   Count: float, no-data: -1
+ -   Maximum Uncertainty: float, no-data: -1
+- Metadata:
+ - For the Taxon dimension, provide [Scientific Name table](https://github.com/FAIRiCUBE/data-requests/issues/71#issuecomment-1819084964)
+- input format: [CSV](https://github.com/FAIRiCUBE/data-requests/blob/main/encoding-examples/datacube_nl_farmland_birds_1.csv) with columns Year, EEA Grid Cell, TaxonID, Count, Uncertainty
+ - EEA reference grid cell identifiers, e.g. 1kmE5432N4321 or 250mE1025N22000
+ - In contrast to the datasets to date, GBIF provides Lat/Long through a grid cell id for the LAEA 10m grid
