The aim of the work was to investigate the possibilities of WebXR technology in the field of spatial planning. The resulting application presents the potential of visualization and analysis of geospatial data in virtual and augmented reality environments. The application functions as a website. It contains four VR examples that enable virtual tour of three-dimensional models representing various areas of the city of Poznań. It also has two AR examples for loading models via a smartphone camera. A working application can be found at this link.

• The source code can be downloaded from Github repository
• When using the application, it is recommended to use devices such as a smartphone (intended for AR and VR) and specialized VR goggles i.e. Oculus Quest, HTC Vive (for examples related to VR)
• When editing the source code or in order to test the application locally via a PC, it is recommended to use the plug-in for web browsers called WebXR API Emulator
• When using the application via a smartphone, it is recommended to download Google AR Services

The following libraries were used to create the application:

• Three.js
• CanvasUI
• WebXR API The following software was used to create 3D models representing areas of the city of Poznań:
• Blender and extension BlenderGIS
• QGIS 3.20 and plugin Qgis2Threejs

The spatial data used in the app comes from:

• SIP Geopoz Poznań
• Google Earth Engine

The application has been tested in the area of ​​usability and suitability using the SUS scale and in the context of suitability in the spatial planning process. Potential applications are:

• Social partycypation
• Remote field inventory
• Presentation of the planned scale of the investment
• Real time modelling in VR
• Verification of the assumptions of the city plan
• Analysis and visualization of 3D models and spatial data
• SmartCity
