topoJSON
An extension of GeoJSON that encodes topology for efficient, compact geographic data representation.
What is topoJSON?
TopoJSON is a geospatial data format that extends GeoJSON by encoding topological relationships between geographic features. It solves the problem of redundancy in traditional GeoJSON files by representing shared boundaries only once, resulting in significantly smaller file sizes. This makes it ideal for web mapping and data visualization where bandwidth and performance are concerns.
Developers and data scientists working with geographic data for web mapping, data visualization, or GIS applications who need efficient data transfer and storage.
Developers choose TopoJSON because it reduces geographic data file sizes by up to 80% while preserving topological relationships, enabling faster loading times and more efficient data processing compared to standard GeoJSON.
