Piero

Appearance

What is Piero ? ​

Piero is a free and open source (FOSS) project to view and analyze 3D geospatial data on the web.

It is both an app and a library (@giro3d/piero).

TIP

When to use the app and the library ? If you don't want to customize your own deployment of Piero, use the app version. If you want to specify your own modules and theme, use the library.

NOTE

The demo application is available at https://piero.giro3d.org/.

Capabilities ​

Piero is able to load a broad range of data sources, such as vector and raster data, point clouds, 3D Tiles, and much more. Each data source is implemented as a module, and it is very easy to extend Piero to support your own datasets (or replace the default implementation for a data type).

Geographic vector data ​

  • GeoJSON
  • KML
  • GPX

Raster data ​

  • TMS
  • WMTS
  • WMS
  • OpenStreetMap
  • Mapbox tilesets (requires a Mapbox API key)
  • GeoTIFF

3D data ​

  • 3D Tiles
  • LAS/LAZ point clouds
  • Potree point clouds
  • glTF
  • OBJ
  • IFC
  • CityJSON

Search and geocoding ​

Piero is able to search through various geocoders, such as :

  • French address database (BAN)
  • Photon Geocoder
