You can buffer and intersect polygons using ArcGIS Maps SDK by utilizing the geometryEngine for synchronous spatial operations or geometryEngineAsync for non-blocking processing. These modules handle intersection, union, and difference calculations directly in the browser.

Compute geodesic area and measurements for ArcGIS geometries by calling methods within the geometryEngine and geodesicUtils modules. These tools provide accurate distance and area calculations that account for the earth's curvature.

Yes, the ArcGIS geometry engine supports 3D meshes and projection tasks. You can construct and manipulate 3D meshes alongside points and polygons, while the projection module handles transforming coordinates between different spatial references.

The best way to densify lines and format coordinates is using the densify operation within the geometry engine and the coordinateFormatter utility. Densify adds vertices to linear geometries, while coordinateFormatter parses and outputs coordinate notation.

Use geometryEngineAsync instead of geometryEngine for spatial operations when handling large or complex geometries that could block the main thread. The async module performs buffering, union, and intersection tasks in the background to maintain UI responsiveness.
