Is there a Data Driven Pages Tutorial?
Here is what we want to do. The user digitizes a rough polygon in ArcMap or a Web application. This polygon is passed to a geoprocessing task that produces a map centered on the polygon then converts that to a PDF. The PDF part is easy but I'm not sure where to start on the map. We don't have a index later so to speak or would be just create one by creating a polygon of a map extent that fully contains the user's polygon?
