Functions for SuperMap Service GIS Products

The following table shows the function matrix of the three different products of SuperMap Service GIS products.

SuperMap IS .NET is a development platform for Internet geographic information publishing. It can provide solutions at different levels for enterprises and organizations, and meet all the requirements of Service GIS application. With SuperMap IS .NET, users can build Internet or intranet GIS service website based on maps, as well as customize a geographic information service system in a fast way.

SuperMap IS .NET achieves an ideal high performance, and has many favorable features, such as excellent integratibility of multiple data sources, massive data accessibility, server cluster, multitier cache, as well as supporting concurrent collaboration of many map engines. Taking the server cluster as an example, SuperMap IS .NET offers strong capability of a server cluster, it supports either stand-alone server/multiple application cluster or multiple server/multiple application clusters. In addition to high system reliability and improved concurrent accessibility from the clients, it also has better extensibility, i.e. to cluster multiple low-end servers with high performance/price ratio to achieve the computing power of a high end server or even a supercomputer, thus, hardware investment can be substantially reduced.

System Architecture

Figure 1 shows the architecture of SuperMap IS .NET and table 3 further explains it.

Service Structure	Description
Client	SuperMap IS .NET supports the most popular client side applications such as IE, Firefox, Netscape, Mozilla, etc. Moreover, it supports desktop application program, mobile devices and other Internet based applications. The clients can connect to the websites built based on SuperMap IS .NET application easily in various forms.
Web Server	SuperMap IS .NET provides Web Controls and Web application templates, most of web applications based on WebGIS can be used directly or you can extend Web Controls and the templates to build the application quickly.
Application Server	SuperMap IS .NET application server is developed based on .NET component technology. Multiple engines of different types can run at the same time. The system has provided many predefined GIS service engines as well as a custom engine for special and complicated application.
Data Server	SuperMap IS.NET has integrated with SuperMap SDX+, it can store both spatial and non-spatial data into large-scale DBMS such as Oracle, SQL Server, Sybase and DB2, etc. With SuperMap SDX+, SuperMap IS.NET can effectively manage massive vector and raster data and publish to Internet /Intranet.

This product can be used to publish spatial data as well as provide spatial information service in the following two aspects:

This type of system usually provides Internet GIS service for public with daily life related spatial information, such as bus transfer, location based service, route analysis etc., which results in huge concurrent access volume. With the help of server cluster and multi-layer spatial data cache mechanism offered in SuperMap IS .NET, the bottleneck of plummeting system performance due to a large amount of concurrent access has been resolved effectively to ensure a reliable and efficient public service oriented WebGIS publication system.

The GIS services provided by SuperMap IS .NET can be applied to a number of industries for improving their management and service, such as location information provider, e-Business website, meteorological information publisher, agricultural information website, public health information publishing, tourist information publishing, environmental information website etc.

This functionality offers popular WebGIS functions such as interactive digital map operation, query and some more advanced spatial analysis and application model such as shortest/optimal path analysis, buffer analysis, bus route and transfer query.

SuperMap IS .NET supports online editing, allowing multiple users to concurrently edit spatial data online, implementing remote data collection and maintenance.

The GIS application service can be remotely managed using the standard web program, such as Internet Explorer. System parameters can dynamically take effect without stopping the GIS service.

SuperMap IS .NET has three editions, which are Professional Edition, Enterprise Edition and Development Edition. Basically, their functions are the same but with different performances.

　　◆ Development edition is designed for application development, and you can develop, debug and run the application. The high performance/price ratio can greatly reduce your development cost.

　　◆ Professional edition can be used to deploy the system, allowing parallel access of unlimited volumes of users.

　　◆ Enterprise edition is oriented for high-end web application system with improved system response capability and parallel accessibility.

Various developing modes in SuperMap IS .NET are available, from UI customization, Web application development, customized engine and customized service application. There are different-level SDKs available for users’ choice.

A series of ASP .NET server side controls such as MapControl are available, these WebControls are main SDK for implementing WebGIS functionality with drag-and-drop programming and consistency of design time with runtime. It enables developers to quickly implement the system and view the running effect of the system at any time.

On the basis of web controls, user friendly application templates are provided, fast transplantation and template reuse will greatly facilitate the customization.

AjaxMap is a map control encapsulated by SuperMap IS .NET using Ajax technique, with which the user can build Web user interface with direct, reusable, rich and dynamic features similar to desktop applications. A better user experience is obtained when the client is accessing a WebGIS website built by AjaxMap. Even if the data volume is large, during the process of reading data, what the user faces is no longer white screen but the previous page, and when all the data has been received, the related part of the page will be updated in a flash.

SuperMap IS .NET adopts a complete open component architecture, allowing users to extend functions themselves and integrate with SuperMap IS .NET functions and services. This scalable map engine development is substantially useful for industry application oriented developers by developing the specialized engine for a specific industry to reduce development duration of concrete projects.
