MapBundle
Bundled, offline map data for .NET apps — borders, cities, waterways and base layers — shipped as FlatGeobuf inside NuGet packages. Data is derived from OpenStreetMap under the ODbL; cities, rivers and lakes come from Natural Earth (public domain).
Packages
| Package | Contents |
|---|---|
MapBundle |
Core runtime. Loads the bundled .fgb layers. No data of its own. |
MapBundle.World |
The whole world (every continent merged). |
MapBundle.[Region] |
A single continent or country (for example MapBundle.Europe or MapBundle.Monaco). |
Install the core package plus the area required:
dotnet add package MapBundle.Monaco
A data package copies its FlatGeobuf files into a maps/<Region> folder beside the app at build time, and the MapBundle core reads them from there. Layers can instead be converted to another format and/or rendered to an image at build time.
Usage
var map = Maps.Open().Load("Monaco");
var borders = map.Borders; // country polygons
var cities = map.Cities; // populated places
var states = map.StatesProvinces; // admin-1 polygons
var rivers = map.Rivers; // rivers
// also: map.Lakes, map.Coastline, map.Land, map.Ocean

Layers are read on demand and returned as GeoConvert FeatureCollections (coordinates are WGS84 longitude/latitude).
Layers
🗺️ Borders · 🏛️ StatesProvinces · 🏙️ Cities · 〰️ Rivers · 💧 Lakes · 🏖️ Coastline · 🟩 Land · 🌊 Ocean
A layer is omitted from a package when the source has nothing for that region (for example Ocean and Coastline for landlocked countries). Roads, railways, buildings, land use and terrain are intentionally excluded.
