Zoom Goto Address (Geocoding) Data
With a geocoding database installed on your server, map authors can add the
Zoom Goto US Street Address category to their maps. Autodesk MapGuide
Author comes with a predefined location category called “US Street Address.”
When map authors activate this category, they access the geocoding database
that you installed on your server (see “Adding Geocoding Data” on page 91).
When the category is in place, users can type an address or ZIP code and
zoom directly to that location on the map. For more information, see
“Creating and Modifying Zoom Goto Location Categories” on page 146.
Working with Raster Images
Raster images are pixel-based images, such as digital photographs (satellite
images, for example). Raster images are very useful as background images
underneath your vector data, for example, an aerial photograph of a city with
a layer of streets overlaying it.
Autodesk MapGuide supports various raster image file formats. The following
section contains a complete list of supported file formats.
Raster Image File Formats
The following table provides a brief description of the raster image file
