Essential vocabulary

Cartographic display

StreetMap Premium data is shown as a map. StreetMap Premium provides a high-quality, cartographic street map display on which you can easily perform geocoding, location plotting on the map, or generate detailed turn-by-turn directions. StreetMap Premium provides high-quality cartographic display for streets, routes, and roads, as well as places, boundaries, hydrology, landmarks, and land use.

Classic Locators

The classic locators are the ones that have been included with StreetMap Premium over the last few years. (See the classic locator deprecation notice.) Classic locators are identified by the extensions *.loc and *.loc.xml for composite locators and by the extensions *.loc, *.loc.xml, and *.lox for individual locators. Classic locators are named after the type of address information contained within, such as point address, street address, street name, and postal, for example. The classic locators are supported for use in ArcGIS Desktop (both ArcMap and ArcGIS Pro) as well as ArcGIS Enterprise for publishing geocoding services.

The address locator can be used to find a location of an address (a house number on a street, street name, postal code, or city), geocode a table of addresses, or get the address of a point location.

StreetMap Premium supplies an abundance of locators. Many countries have locators and most of those have multiple locators. Countries with the best coverage have all six standardized levels of geocoding: PointAddress, StreetAddress, StreetName, PostalLocality, Postal, and AdminPlaces. These standardized levels represent individual locators. Global composite locators are provided by combining the individual locators. In addition to global composite locators, there are local composite locators as well as centroid locators.

Point Address Locator

Used for finding address locations in a country.

Street Address Locator

Used for finding street addresses in a country (for example, 12 Concorde Place, Toronto, Ontario).

Street Name locator

Used for finding street names in a country (for example, Calle Agüero, Buenos Aires, Argentina).

Postal code by locality locator

Used for finding postal codes within a locality (for example, 10781, Berlin, Germany).

Postal locator

Used for finding postal codes in a country (for example, 2521 EN, Netherlands).

Administrative places locator

Used for finding administrative places such as municipalities, colonias, blocks, or cities.

Centroid locator

Used for finding the centroid of a feature, such as street, block, postal code area, or administrative place.

Composite locator

A composite address locator consists of two or more individual locators or geocode services. Composite locators support multiple levels of geocoding for individual countries. The six standardized levels of geocoding are combined into a global composite locator for each country. In addition to a global composite locator, some countries have a local composite locator that uses localized input mapping fields.

Input mapping fields for addresses are standardized across the global composite locators and include the following fields: Address, Postal, Neighborhood, City, Subregion, and Region. However, some countries do not utilize all four administrative place fields as input:

  • Neighborhood—smaller than a city
  • City—city or equivalent
  • Subregion—typically larger than city but smaller than region
  • Region—state or province or equivalent

Data dictionary

A compilation of information about the data. Each layer is carefully defined in the data dictionary, which is part of a detailed help documentation provided with every release. The items are arranged by geometry type (points, lines, and polygons), tables, and reference. Within those, the topics are organized alphabetically.


StreetMap Premium has geocoding data for more than 100 countries. StreetMap Premium enables you to geocode and reverse geocode addresses. View StreetMap Premium product coverage for a list of countries where geocoding is available.


The process of transforming a description of a location—such as a pair of coordinates, an address, or a name of a place—to a location on the earth's surface.

Reverse geocoding

The process of transforming a location on the earth's surface to the nearest address or intersection based on a specified search distance, in other words, getting an address from a location.

Geocoding quality level

The geocoding quality level is Esri's relative indicator for the quality of geocoding. It is a function of the degree of street-level address coverage in a country, knowledge of a country's address styles, and geocoding performance for addresses in that country.

For a list of levels by data provider, product, and country, see product coverage.

Geocoding results file output field definitions

Loc_name (when using classic composite locators)

This field lists the individual locator that geocoded each address. The standard locator names are PointAddress, StreetAddress, StreetName, PostalLocality, Postal, and AdminPlaces.


The match type for an address. Possible values include the following:

  • PointAddress—Address points with associated house numbers and street names
  • BuildingName—Address points with an associated building name
  • StreetAddress—Street centerlines with address ranges
  • StreetInt—Street Intersections
  • StreetName—Street centerlines with associated street names (no numbered address ranges)
  • Admin—Administrative areas such as regions, states, and provinces; typically the largest administrative area
  • DepAdmin—Administrative areas such as regions, states, and provinces; typically smaller than an Admin Area
  • SubAdmin—Administrative areas such as municipalities and cities; typically smaller than a DepAdmin Area
  • Locality—Administrative areas such as municipalities, cities, and neighborhoods; typically the smallest administrative area
  • PostalLoc—Postal code points combined with administrative boundaries
  • Postal—Postal code points
  • PostalExt—Extended postal code points such as the USPS Zip Plus 4


The fully matched address, formatted in the local country address schema. This is the correct address format based on address standards for a country.


A code indicating whether the address was matched; values include the following:

  • M—Matched
  • T—Tied (meaning that more than one match candidate has the same score)
  • U—Unmatched


The score is a value assigned to all potential candidates of an address match. The match score is based on how well the locations found in the reference data matches with the address data being searched. A score can range from 0–100, 100 being a perfect match.

  • 0–100

Side (when using PointAddress and StreetAddress locators)

This field indicates on which side of the street (L or R) the matched address falls.

DisplayX / DisplayY (when using PointAddress locators)

These fields store the decimal degree coordinates for the parcel or rooftop centroid associated with each address, as the geocoded point feature is located on the street segment near the main entrance to the property.

ZIP4_TYPE (North America only)

This field is populated if LOC_NAME is ZIP4.

The possible values for data provider HERE are the following: a value of 1 indicates that the latitude and longitude are accurate to the ZIP+4 centroid (more accurate); a value of 2 indicates that the latitude and longitude are accurate to the ZIP+2 centroid (less accurate).


The physical distance in meters from a candidate to a specified location. The Distance output value is calculated for each candidate when the Location input parameter is passed in a request using the Find or findAddressCandidates methods. If the Location parameter is not passed in a request, then the value of Distance is zero.

Historical traffic data

The data stores traffic flow information by day of the week and time of day; therefore, using this historical traffic data will result in more accurate travel times. For example, routing through the city at 7:30 am on a weekday will take longer than routing through the city at midnight. Historical traffic data can be utilized by specifying start times when creating routes using the Find Route tool or Network Analyst. Historical traffic is based on the average of observed speeds over the past two years. A few specific kinds of links are not covered in historical traffic, because they are not navigable roadways: ferry links, rail links, and any link that is not marked as accessible by emergency vehicles. See Routing. For a list of the presence of Historical traffic data by data provider, product, and country, see product coverage.

Locator Update

A Locator Update refers to a quarterly release of a new style of locators similar to the ones used for the ArcGIS Online World Geocoding Service. Locator Updates are released on My Esri on a quarterly basis (Q1, Q2, Q3, and Q4) for all five StreetMap Premium regions (Asia Pacific, Europe, Latin America, Middle East and Africa, and North America).

Map document

Each release of StreetMap Premium provides a map document specific to that release. Its table of contents is organized into group layers by scale ranges from very small to very large. Each scale range group layer contains thematic group layers, such as Places, Roads, Boundaries, Hydrology, Landmarks, and so on. Typically, there are two or three scale-dependent datasets within each thematic group layer. These layers include feature density, level of generalization, symbolization, and labeling.

The contents of similar layers within the thematic group layers vary based on the scale range group layer they are in. For example, the layers in the Hydrology thematic group layer will display slightly different features from one scale range group layer to another, allowing each scale range group layer to show the most scale-appropriate features.

This scale-dependent approach to layer organization allows all the layers of the same scale range to be contained within a single group layer. The thematic group layers can be easily expanded to show the various datasets available at that scale. This permits an entire scale range group layer or a thematic group within that group layer to be turned on or off with a single click. The layers within a thematic group can also be individually turned on and off. For example, you can turn off the entire 2.5k–0 scale group layer, turn off the entire Points of Interest thematic group layer, or just turn off the Parks and Recreation layer in the Points of Interest thematic group layer.

Dynamic label placement is used throughout the entire map document. The labeling is scale dependent and based on size or importance. For some layers, label classes have been defined but are not turned on.

New Locators

The new locators are a new style of locators similar to the ones used for the ArcGIS Online World Geocoding Service. However, since StreetMap Premium utilizes primarily HERE data for the source of address data, and the ArcGIS Online World Geocoding Service utilizes HERE data plus other vendors or public sources of information, some countries' geocoding results may vary. The new locators are identified by the extensions *.loc and *.loz. Instead of having a composite locator that references multiple individual locators, there is just a single new locator that contains the data for all of the multiple individual locators. When using these new locators, it is always highly recommended that you run the most recent releases of ArcGIS Pro and/or ArcGIS Enterprise. Visit System Requirements for the latest information on each release. Use of the new locators in ArcMap is not supported, except when published as a geocoding service through ArcGIS Enterprise


With the StreetMap Premium street dataset you can create routes using the ArcGIS Find Route tool or the ArcGIS Network Analyst エクステンション. StreetMap Premium provides a routing service or network dataset that allows you to calculate point-to-point multistop routes using a variety of options to affect and display the results. You can calculate the quickest or shortest route, specify network restrictions to exclude (or include) certain road types from (or in) the route, define network barriers to exclude specific road segments from the route, optimize the stop order to find the most efficient route, and utilize the different speed values to simulate real-world driving conditions. You can also make the route time-aware by defining a trip start time. This enables additional data-dependent functionality such as time-based turn restrictions and integration of historical traffic information into the route calculation.

For a list of Mapping/Routing levels by data provider, product, and country, see product coverage.

Impedance options

Impedance options find the shortest route either distance-wise or time-wise. Impedance options are provided in different units and travel speed sources, and as truck-specific. Some examples are Kilometers, Miles, Minutes, TimeAt1KPH, WalkTime, and TruckTravelTime.


Trucking restrictions can be accessed along with the other StreetMap Premium restrictions in ArcGIS through the Find Route tool or Network Analyst. These restrictions are available in the routing service or network dataset and they allow the route to be fine-tuned, depending on the vehicle used and legal and physical characteristics of the street segments.

Trucking restrictions fields

Trucking restrictions are fields that define restrictions such as dimensional (for example, weight, length, or height of a truck, and trailer related), load related (for example, hazardous material), speed limit related, and whether a street segment is designated as part of a prohibited or a preferred truck route. The fields are found in the layers Streets for network (Routing_Streets) and Streets and as part of the routing service or network dataset. See Routing.

For a list of the presence of Trucking restrictions by data provider, product, and country, see product coverage.
