## Key capabilities

### Geospatial data management
- **Comprehensive vector and raster geodata storage**  
  Upload or create geospatial datasets and manage them as structured spatial databases via the web interface or REST API.

- **External PostGIS database connection**  
  Create vector layers backed by external PostGIS databases. Style them, publish them on Web Maps, and expose them via standard services.

- **Coordinate reference systems management**  
  Define custom CRS and use them consistently for measurement and data export.

### Web map and data publishing

![NextGIS Web web maps](doc/images/ngw_map.webp)

- **Interactive Web Maps**  
  Create unlimited interactive Web Maps using the built-in map engine. Web Maps include layer management, advanced search, filtering, printing, and measurements.

- **Tile and OGC services publishing**  
  Publish data as:
  - Raster and vector tiles
  - OGC WMS, WMTS, WFS
  - OGC API – Features
  - Cloud Optimized GeoTIFF

- **External services support**  
  Connect third-party TMS, WMS, and WFS services and use them directly in Web Maps.
  
  Store rasters in the Cloud Optimized GeoTIFF format on connected S3-compatible storage systems.

### QGIS-native collaboration

![NextGIS Web QGIS integration](doc/images/ngw_qgis.webp)

- **Full QGIS style support**  
  Use QGIS styles to visualize datasets.

- **Hub for QGIS-centered teamwork**  
  Publish QGIS projects to NextGIS Web and edit server-side data directly from QGIS using the [NextGIS Connect](https://github.com/nextgis/nextgis_connect) plugin.

  See the NGW/QGIS integration extension: [nextgisweb_qgis](https://github.com/nextgis/nextgisweb_qgis) 

### Built-in version control for vector data

![NextGIS Web Feature versioning](doc/images/ngw_versions.webp)

- **Track the full history of vector datasets**  
  Who changed what, when, and how. Roll back changes or audit edits without data loss.

### Editing and attachments
- **Built-in vector layers editor**  
  Create and modify vector layers directly in the web interface.

- **Attachments management**  
  Attach photos and documents to vector layer features. Preview and manage attachments directly on Web Maps.

### Security and access control

![NextGIS Web permission management](doc/images/ngw_permissions.webp)

- **Flexible permissions management**  
  Create users and groups with fine-grained access control, down to individual layers or maps.

### API and extensibility
- **Powerful REST API**  
  All functionality is accessible programmatically: users, layers, services, maps, permissions, and more.

- **Frontend integration**  
  Build custom web applications using [NextGIS JavaScript libraries](https://github.com/nextgis/nextgisweb_frontend)
