MERLIN Online allows a user to create a map for any location in
Maryland, including their choice of base map and user selectable
data. Users can point to a location on the map and receive
information about that site. Another powerful feature of the system
is access to information that helps to better understand the data
being viewed, such as the origin of the data, how it was created,
accuracy and age.

Other features include measuring tools, a map legend, hyperlinks
from data layers to other web pages, Frequently Asked Questions
(FAQ) and a Help Guide that can be printed to assist a user as they
learn to navigate through the system. Users must have a current web
browser with Adobe Flash Player installed.

MERLIN Online was developed for internal and external customers
because everyone is “hungry” for maps to help make better, informed
decisions. Promoting MERLIN Online supports the Department’s
mission, provides for wise economic development in Maryland and
promotes stewardship of our natural resources. Use it today at
