ArcGIS API for JavaScript 4.1

<\/HEAD>

The ArcGIS API for JavaScript<\/A> provides efficient support for creating web mapping apps that utilize the spatial capabilities of the ArcGIS platform. This allows, for example, the development of applications that visualize maps, integrate preconfigured content and services, create directions and routes, perform geometric calculations, and much more – all for common browsers on desktops and mobile devices.<\/P>

<\/P>

Thanks to support for HTML5 and CSS3 components, the performance and flexibility of the apps can be increased. Also helpful are practical widgets, flexible tools for UI configuration, as well as pop-ups for implementing responsive design.<\/P>

With the 4.x series of the ArcGIS API for JavaScript, Esri has released a newly revised version that now also supports web maps and functions in 3D. The goal was to make using 3D web maps as easy as 2D web maps. For this purpose, the API was fundamentally redesigned. A new unified programming model enables the same implementation of layers, rendering, tasks, geometry, symbology, pop-ups, and navigation in 3D web scenes as for 2D applications. Additionally, atmosphere, lighting conditions, and camera angles can be modified – this ensures a particularly realistic representation.<\/P>

The highlights in the new version 4.1 are:<\/P>

For new projects it is generally recommended to use the 4.x series unless functions from the 3.x series are missing. A
