iTowns

iTowns is an open-source framework designed for web-based visualisation, navigation and interaction with 2D and 3D geospatial data on globes and maps. Built on Open Geospatial Consortium (OGC) open standards, it is developed with data and service interoperability in mind. It seamlessly integrates with geographical services, offering support of standard raster and vector data, including aerial imagery and terrain models. The framework supports large, heterogeneous 3D datasets such as OGC's 3D Tiles, making it ideal to build application for urban-planning and environmental monitoring. It can be easily extended to support other open formats, offering a highly customizable platform for developers.

iTowns is a geographic commons, developed collectively by a diverse community of contributors, comprising independent developers, public organizations, research laboratories and private companies. It aims to provide an European alternative to Big Tech products which often overlook a broad class of users. Instead, iTowns offers a modular framework to build a wide range of use cases, including visualisation, GIS, environmental and educational applications, making it versatile and adaptable for different geospatial projects.
