# SpatialData **Domain:** Spatial Omics / Bioimaging / Neuroinformatics **Doc Type:** Technical Format Node **Maturity:** Active Ecosystem **Related:** [[OME-Zarr]], [[Zarr]], [[Multimodal Neural Data]] --- ## Definition **SpatialData** represents spatially resolved biological data—including images, labels, shapes, points, tables, coordinate systems, and transformations—in a common object and storage model. Its Zarr representation extends OME-Zarr for spatial omics and related multimodal data. ## Architectural role SpatialData allows microscopy, segmentation, cell annotations, expression tables, and geometric regions to remain related in shared coordinates. This matters when structural, molecular, and functional evidence must be jointly traversed. ## Primary source - [SpatialData glossary](https://spatialdata.scverse.org/en/stable/glossary.html)
