Interested in adding fast, modern Web mapping applications to an Internet or intranet site? Esri's ArcGIS Web Mapping APIs are now available for free for noncommercial use, letting you easily embed, consume, and deploy mapping capabilities in Web or service-oriented desktop applications.
Using ArcGIS Web Mapping APIs, you can offer users rich maps and GIS capabilities similar to those in desktop mapping applications but with Web benefits. For example, you can design applications that offer compelling graphics and an intuitive interface with a consistent user experience across multiple browsers and platforms. Applications built from Web Mapping APIs often perform better and display better maps than traditional server-side applications. In particular, applications that avoid round trips to the server by processing locally on client machines can also improve server performance.
Often, GIS Web applications need to include geospatial functionality that goes beyond simply displaying a map with points. For instance, an appliance repair company may want to use a geoprocessing task to generate drive-time polygons on a map to estimate the length of service calls, then use a routing task to calculate the routes and directions before dispatching vehicles on those calls.
For these types of functions, these APIs provide a set of task classes to perform GIS tasks. These classes allow developers to easily write application-specific code to extract information such as addresses, geometries, and attributes from ArcGIS services and present that information to users. These APIs also allow graphics to be drawn on top of the map (e.g., multipoint, polyline, polygon, and rectangle). For example, a parcel viewer application could contain map tools that allow users to draw on the map to execute a spatial query or measure distances, radius, and areas to provide additional interaction and analysis. In addition, the Web mapping APIs provide components to display maps that support multiple map projections, as well as both dynamic and cached (tiled) map services.
With the APIs, developers can include a variety of tasks in their applications:
