GeoConvert

GeoConvert

Convert maps between geospatial formats, with no third-party dependencies — only the .NET base class libraries. Also renders a bounding box to a PNG raster or an SVG vector image.

Supported formats: GeoJSON, TopoJSON, Shapefile, FlatGeobuf, KML/KMZ, GPX, WKT, WKB, CSV, GeoParquet, PNG (write-only raster), and SVG (write-only vector).

// Formats are inferred from the file extensions.
GeoConverter.Convert("cities.geojson", "cities.kml");
GeoConverter.Convert("roads.shp", "roads.fgb");

// Or read into the common feature model, then write a different format.
var collection = GeoConverter.Read("roads.shp");
GeoConverter.Write(collection, "roads.fgb");

A geoconvert command line tool is also available as a separate package: GeoConvert.Cli.

See the GitHub repo for full documentation, samples, per-format limits, and PNG rendering options.
