About SuperGIS Server Ultra Website

Ultra website, the web template based on JavaScript, can help developers easily create a map website including basic navigation tools without any plug-in. With SuperGIS Server Manager, you can rapidly create an Ultra website. If you are capable of writing codes, you can customize your own SuperGIS Server Ultra website.

To simplify the complexity of the program, Ultra website is based on object-oriented concept and applies JavaScript, which is direct translation, to repack the associated functions into tens of function objects to carry out the experience of calling objects. It also uses VML (Vector Markup Language), AJAX (Asynchronous JavaScript and XML) technologies for real-time interactive usage.

Co-working with the regular map service, Ultra website allows users to link to it through web browsers to navigate the map and query layers, which is the basic type of website.

Ultra website also supports Map Cache Service, if a Ultra website uses Map Cache Service, it can be called Ultra for Cache website. Ultra for Cache website communicates with the back-end sever with ASP.NET webpage through ActiveX COM component (SWGClient). The regular web map is mainly for navigation and positioning; however, the tradition server needs to calculate and render for each connection separately,which takes time and resources. Ultra for Cache website will try to split the rendered map into parts with number in the fixed extent and stores them, and then presents the image of the correct extent on browser by putting together these images when navigation or positioning. In this way, the visual effect and manipulation of web can be enhanced significantly, the burden of server can be reduced so that server spares more resource to handle the query.

Since Ultra for Cache website uses Map Cache technology to render the map, please note that you need to set up Map Cache Service as your map service when creating Ultra for Cache website, so that the website can work and present map imagery, or the map imagery cannot be presented successfully.

In addition to the regular Map Service and Map Cache Service, users can create Ultra website with Feature Service. The Ultra website with Feature Service is called Ultra for editing website, which allows users to on-line edit the service layers through the web browser. The difference between Ultra for editing website and Ultra website is that Ultra website provides only the regular map navigation and query, while Ultra for editing website provides not only the basic map functions but also on-line editing function. Ultra for editing website allows users to add and edit point, line and polygon features online.

Ultra for editing website should work together with Feature Service so that the website enables to handle the manipulation of online feature editing. The layers of Feature Service published by SuperGIS Server will be given with a GID field as well as the value automatically, so that the Feature Service can be editable. GID can be termed as GUID (Global Unique Identifier), it is the identifie that SuperGIS Server uses to identify the specific features. However, Ultra for editing website must update the map features in real-time, it doesn't support Map Cache Service settings.
