TileDB 101: Geometries

This article covers the basics of how to use TileDB arrays with geospatial vector data. I will show how to ingest the geometries from a shapefile into a TileDB array and how to then read the data from this array. I will also show how to use the polygons from the geometry array to slice and read data from a point cloud (also ingested into a TileDB array). Before proceeding with these tutorials, I recommend you read the blog Why TileDB for Geometries. In this introductory tutorial I will focus on a geospatial application, noting however that TileDB’s geometries feature is applicable to other use cases as well (such as spatial transcriptomics — we’ll cover other use cases in future tutorials).
