About StreetMap USA data

StreetMap USA is a dataset in Smart Data Compression (SDC) format that provides nationwide streets display, routing, and geocoding for the United States. It contains a TIGER 2000-based streets dataset, enhanced by ESRI and Tele Atlas and prepared for routing within the StreetMap Find Route dialog box. StreetMap USA data is provided in the ESRI Data & Maps media kit on the ESRI Data & Maps/StreetMap USA DVD. To use the entire StreetMap USA dataset for display in ArcMap, open the StreetMap USA map document (.mxd) located in the USA folder.

More recent streets data for the United States, Canada, and Europe are available with the StreetMap Pro and StreetMap Premium products. For more information, visit www.esri.com and select ESRI Data under the Products tab.

StreetMap USA map document

The StreetMap USA map document (.mxd) is an integrated interactive map display that serves as a general purpose basemap for performing routing, geocoding, and cartographic display of the StreetMap USA data. The .mxd supports seamless ad hoc panning and zooming from the full U.S. extent down to the detailed streets level. It displays various road categories, such as interstate highways and local roads, and other features including state boundaries, lakes, landmarks, and airports.

The StreetMap USA table of contents is organized at two levels. It is mainly organized into thematic group layers, such as Roads, Water, Landmarks, and so on. Within each thematic group, the data layers are organized according to their usable scale range. Typically, there are three or four scale-dependent datasets within each thematic group layer, for example, Interstates, Highways, and Local Streets. These layers provide the appropriate 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. There are a few exceptions, but in general, the ranges follow the organization below:

      National Level: Greater than 1: 20,000,000

      State Level: 1:1,500,000 to 20,000,000

      Regional Level: 1:200,000 to 1,500,000

      Local Level: 1:20,000 to 200,000

      Detail Level: Less than 1:20,000

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 the various datasets arranged by display scale. This permits an entire thematic group to be turned on or off with a single click. The scale-dependent layers within a thematic 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 Local Streets layer.

Dynamic label placement is used throughout the entire StreetMap USA.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 USA.mxd. If you want to use the ADO to alter the cartographic appearance, you can access this command by right-clicking in the data frame or on the data frame name in the table of contents.

You can zoom to any area of the StreetMap USA map document and convert the compressed street data into other types of feature classes, such as shapefiles, personal geodatabases, or file geodatabases.

Using the StreetMap USA map document

The StreetMap USA dataset provides an ArcMap document (StreetMap USA.mxd) that contains the StreetMap USA group layer for routing and geocoding. If you open the StreetMap USA.mxd file with ArcMap, you'll see the StreetMap USA layers in the table of contents. It contains different layers: state boundaries, lakes, rivers, landmarks, cities, highways, urban areas, airports, roads, and streets. The StreetMap USA layers provide different levels of detail at different scales.

The StreetMap USA layers are defined with default scales that display the appropriate types of features. When the StreetMap USA.mxd is opened or the StreetMap USA group layer file is added in ArcMap, a map of the United States is displayed. The map shows the state boundaries, interstate highways, major cities, and major water bodies. You can click an area or drag a box on the map using the Zoom In tool. ArcMap displays a map of the specified area and draws the default set of features.

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 USA.lyr file, which you can add to any other map document, is provided on the ESRI Data & Maps/StreetMap USA 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 USA.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.

Using the StreetMap USA routing service

The StreetMap USA dataset includes a routing service that you can use with the StreetMap Find Route dialog box to find routes within the United States. To use the service, at the top of the Options tab on the Find Route dialog box, browse to the streets.rs file, located in the Usa\Streetmap_usa\Streets folder on the ESRI Data & Maps/StreetMap USA DVD.

Using the StreetMap USA address locator for nationwide geocoding with ArcGIS Desktop and ArcView 9

The StreetMap USA dataset provides a StreetMap USA address locator you can use right away for geocoding addresses in the United States. When you use ArcCatalog or ArcMap for geocoding, you can browse for the StreetMap USA address locator, which is in the Usa\Streetmap_usa\Streets folder on the ESRI Data & Maps/StreetMap USA DVD. The name of the file is StreetMapUSA Locator.loc. There is also a StreetMapUSA Alphanumeric Locator.loc for geocoding alphanumeric addresses, a StreetMapUSA Hyphenated Locator.loc for geocoding hyphenated addresses, and a StreetMapUSA Composite Locator.loc which uses a combination of all three previously mentioned locators.

You can easily create a new address locator in ArcMap using the StreetMap USA streets data on the DVD. Choose US Streets with City State Zip as the locator style and enter the full path to the streets.sdc file, for example, e:\Usa\Streetmap_usa\Streets\streets.sdc.

Using the StreetMap USA address locator for nationwide geocoding with ArcSDE

If you want to allow server-side geocoding with StreetMap in ArcSDE, you can create an address locator using the US Streets with City State Zip style in ArcSDE; this geocodes against the street's data. Before creating a new StreetMap address locator, your ArcSDE server administrator must set up the required parameters and settings. For details, refer to the ArcSDE Installation Guide.
