 A [FlatGeobuf (FGB)](https://flatgeobuf.org/) is a vector file format designed to be served through a standard HTTP server. Its internal structure enables fast and selective data access by leveraging HTTP Range Requests: clients can request only the portions of the file they need, without having to download the entire dataset.
 
 In MapStore, FGB files can be added as layers. Through the Catalog tool, it is possible to configure multiple FlatGeobuf URL sources: each URL is interpreted as a single layer and added to the map directly and efficiently.
