138 Chapter 8 Creating and Publishing a Map
To create a new map, you start with either the map of the world or another
existing map. To create a new map, you can use one of two methods:


Open the map of the world using the File
area and settings you want, and then save it as a new map. Use this
method if you do not have any existing maps, or if you need to create a
map of a larger area than your existing maps.


Open a map of the specific area you want using the File
mand, make modifications, and then save it as a new map. Use this
method if you want to create a map that is similar to an existing map and
uses the same area or a smaller area within it.
For step-by-step instructions, choose Help
and look up "maps, creating."

Changing the File to Use for New Maps

By default, the map of the world shown in the illustration on page 119 is the
basis for any new map you create using the File
Autodesk MapGuide Author. The file used to create new maps is called
Newmap.mwf. If you prefer to start with a different map for all new maps that
you create, you can do so by saving your own map as Newmap.mwf, over-
writing the default new map. For more information, choose Help
Contents, click the Index tab, and look up "Newmap.mwf."
The coordinate system you use determines which projection, center, and unit
of distance measurement you will use for this map. The default coordinate
system is World-Miller, which is an appropriate coordinate system for a map
of the entire world.
Specifying the correct coordinate system is a critical part of setting up the
map. Even if you created the map based on an existing map, you should still
verify that the coordinate system you are using is right for your purposes,
particularly if you are using a much smaller area than the original map. For
more information about how to choose an appropriate coordinate system,
see "Choosing a Coordinate System" on page 113.
