Understanding Autodesk MapGuide

Example of an Autodesk MapGuide application

Autodesk MapGuide applications can be

client-side

or

server-side

. A client-side

application runs in the user’s browser, using the processing power of the
user’s (client) computer. It is typically an HTML page that hosts Autodesk
MapGuide Viewer and contains code to access the objects of the Autodesk
MapGuide Viewer API. A server-side application runs on the server, and is
typically used for generating custom map reports, generating dynamic HTML
pages, and updating map resources such as databases, GIS, or CAD files. In
most cases, applications are a combination of both client-side and server-side
applications, but for the sake of simplicity, the following sections discuss the
components as being one or the other.

Client-Side Application Components

Client-side applications run in the user’s browser. A client-side application is
usually made up of the following components:

A web browser and an HTML page that hosts Autodesk MapGuide Viewer

An MWF that is read by Autodesk MapGuide Viewer and displayed as a
map

Web browser scripts that access the APIs for the browser and Autodesk
MapGuide Viewer
