Designed specifically for web mapping applications which do not involve extensive spatial analysis

Cadcorp SIS WebMap Express has been designed for public and private sector organisations which require the familiar look of widely-used web mapping services, but need to be independent of the map data bundled with those services. It offers an extensible and cost effective alternative to commercially available hosted web mapping services, without having to surrender control over cartography and administration.

There are two components to the application: a website - SIS WebMap Express; and a map server - Cadcorp GeognoSIS® Express.

How it can be used

The application meets the needs of end-users, application developers, and systems integrators alike. SIS WebMap Express can be used as a complete and interactive mapping application. Alternatively it can be used as a component of a larger web application. A common use of SIS WebMap Express is to provide mapping capability to a web site. Visitors to such a website are provided with a map showing the location of a point of interest against a defined map background.

This map is generated on demand by passing to SIS WebMap Express a URL with parameters describing the location and representation of the point of interest, and the map view. With SIS WebMap Express, organisations may consume any Web Map Service (WMS) data source. This can include their own mapping data served by our web map publishing system GeognoSIS Express – as well as WMS data feeds from other sources.

Its composition

SIS WebMap Express is built upon the open source JavaScript library, OpenLayers. This is a mature and established open source product, which has been enhanced by Cadcorp to provide additional flexibility, security, and control. By surrounding it with a .NET wrapper, the need for administrators to use JavaScript to manage the functionality of the application has been removed. Web developers can also customise SIS WebMap using JavaScript and OpenLayers API, and insert custom code directly into .aspx pages.
