As one of the sponsors, and as CTO of MIERUNE, I'll introduce our company by focusing on the technologies we work with.

Founded in 2016, MIERUNE has grown into a technology company specialized in geospatial technology and modern web architecture. In this session, I'll demonstrate how these two domains come together through our actual products and solutions.

GeoParquet is a file format based on Apache Parquet for efficient storage of large geospatial datasets. Well-sorted Parquet achieves better compression and better query performance. However, it is not enough for streaming features with acceptable performance. To address this, I added hierarchical dimension for sorting and achieved better results.

MapboxVectorTiles have changed the geospatial ecosystem. Vector data distribution has become more efficient, map rendering has moved from server-side to client-side, map styling has become more common. But does that mean we no longer need raster tiles? No. Raster tiles still matter.
