The StreetMap North America table of contents is mainly organized into thematic group layers such as Transportation, Hydrology, Landmarks, and so on. Each thematic group may also include sub-groups, such as Rivers, Water Bodies, and Coastal Water. Then within each thematic group or sub-group, the data layers are organized according to their usable scale range. Typically there are three or four scale-dependent datasets within each group layer, for example interstates, highways, and roads. These layers provide feature density, level of generalization, symbolization, and labeling for each scale range. For convenience, these scale ranges are given names that indicate the level at which they are displayed.
This thematic approach to layer organization allows all the layers of the same type to be contained within a single group layer. The thematic group layers can be easily expanded to show additional sub-group layers or the various datasets arranged by display scale. This permits an entire group to be turned on or off with a single click. The sub-group layers or scale-dependent layers within a group can also be individually turned on and off. For example, you can turn off the entire Landmarks group layer or just turn off the Airports sub-group layer.
Dynamic label placement is used throughout the entire StreetMap North America.mxd. The labeling is scale dependent and based on size or importance. A label flag field has been added to many layers to improve labeling options. For some layers, label classes have been defined but are not turned on.
The streets data has been presorted to draw the road classes in the correct
order for cartographic display. The ArcGIS 9 Layer
Drawing Option (LDO) has been implemented for a number of individual layers.
These include city points, landmark points, and streets. The data frame-based Advance
Drawing Option (ADO) is not utilized for the StreetMap
North America.mxd. If you want to use the
You can zoom to any area of the StreetMap North America map document and convert the compressed street data into other types of feature classes, such as shapefiles, personal geodatabases, or file geodatabases.
The StreetMap North America dataset provides an ArcMap document (StreetMap North America.mxd) that contains the StreetMap North America group layer for routing and geocoding. If you open the StreetMap North America.mxd file with ArcMap, you'll see the StreetMap North America layers in the table of contents. It contains many different layers within the thematic group or sub-group layers. The StreetMap North America layers provide different levels of detail at different scales.
The StreetMap North America layers are defined
with default scales that display the appropriate types of features. When the StreetMap North America.mxd is
opened or the StreetMap North America group layer
file is added in ArcMap, a map of
Zooming in on the map or changing the view scale changes the map content if it reaches a different level of detail. For example, at the local level, ArcMap will draw the city map with more details including local streets, highways, urban areas, and airports. Default colors, symbols, and label fonts will be applied to the features accordingly.
You can change the settings, add new layers, or remove layers. You can also save the settings into a layer file. The StreetMap North America.lyr file, which you can add to any other map document, is provided on the ESRI Data & Maps and StreetMap North America DVD.
Group layers can be turned on or off in the table of contents to increase or decrease the feature content of the map display. Entire thematic group layers or the scale-dependent layers within each group layer can be turned on or off to modify the map display. Labeling can also be turned on or off for each layer.
You can also use ArcCatalog to view the StreetMap layers. Choose the StreetMap North America.lyr file from the DVD and click the Preview tab. Use the Zoom In and Zoom Out tools to display different layers of the map.
