Address Lookup

Address Lookup - Thanks to a collaborative effort between State agencies and local jurisdictions, Maryland's Composite Locator was developed to provide a single, robust geocode service for Maryland. The composite locator maps tabular data by matching it against geospatial features from multiple data sources.The composite aspect of the locator refers to its design to match tabular data with the first in a list of data sources. If a match is not found, the locator then "cascades" down the list of data resources searching each for the best match. The composite locator can be accessed via Esri's Desktop software or programmatically via the REST endpoint.

Service Level Objective (SLO):

Address Lookup has a 99.9% uptime service level objective; excluding planned outages, maintenance windows and unavoidable events.

Features and Benefits:

 

Single Address Look-Up

Web users can access the available address look-up to identify single data locations. Users can compare the matching accuracies of the different data sources.

NEW - Batch Address Look-Up

Web users can match multiple addresses in a bulk fashion. Fast and easy to use, drag and drop a file and match up to 1,000 addresses at a time.

Data Sources

The composite locator currently boasts eleven (11) data sources which participate in the cascade. They are a combination of local, state and federal datasets. They include address points, mile markers and place names (e.g. - Oriole Park at Camden Yards).

Composite Locator Code

A snippet of code is available as an example of how to incorporate the geocoder service into an application using the JavaScript programming language.
