ngeo is a feature-rich JavaScript library created to simplify the development of modern, interactive web mapping applications. Built upon OpenLayers, one of the most established mapping engines on the web, and AngularJS, a popular framework for building dynamic user interfaces, ngeo bridges low-level cartographic capabilities with high-level application components. It provides tools, directives, and services for maps, layer management, drawing, printing, querying, catalog navigation, and many other common GIS interactions.

A key strength of ngeo is its modularity. Developers can build fully customized applications by selecting only the components they need, ensuring that final applications remain fast and efficient. This approach also enables the creation of complex geospatial interfaces that remain maintainable and easy to extend over time.

ngeo is widely used in production environments, particularly within the GeoMapFish ecosystem, where it serves as the primary web-mapping client. Its stable architecture, well-defined patterns, and extensive documentation make it a reliable choice for teams building rich, map-centric applications. From public-facing portals to internal tools, ngeo provides the flexibility and power required to meet demanding geospatial use cases.
