System Recommendations & Requirements
Recommendations
A screen resolution of 800 x 600 or higher is recommended.
The map viewing window is resizable, but a larger window will mean more area is visible on the map. |
You should view this site with a fast connection.
MERLIN Online offers many maps and tools for viewing them. Since MERLIN offers so many interactive tools and detailed maps, the map browser and map images are moderately large downloads, and will benefit from a fast connection. |
View the Finding Aerial Photography and Parcel Maps Tutorial.
The tutorial will introduce you to some of the detailed data in MERLIN Online. It will also illustrate most of the tools and features you can use when viewing the maps. |
Web Browser Requirements
Use a modern web browser.
MERLIN Online requires at least Internet Explorer 5.0 or Netscape 4.6, both of which were released in 1999. Most newer web browsers will work correctly with MERLIN. |
Java must be enabled.
Java must be enabled to used MERLIN Online. If you are using a Windows computer, the Microsoft Virtual Machine (VM) is recommended. See the FAQ for more details if necessary. |
Change settings in pop-up blockers.
If your computer has pop-up blocking software installed, it needs to allow pop-ups from www.mdmerlin.net and atlas.mdmerlin.net. Note that Internet Explorer 6 on Windows XP usually includes a pop-up blocker, which needs to be configured to work with MERLIN Online. MERLIN Online does not serve ads, but the site uses pop-up windows for enhanced map browsing and a more functional interface. |
Other Requirements
If your computer is behind a corporate firewall, port 4750 must be open.
Port 4750 on large firewalls must be opened to incoming and outgoing traffic in order for MERLIN Online to display map data. Firewall software intended for home computer use (e.g. ZoneAlarm, Norton Personal Firewall or Internet Security, McAfee Firewall or Internet Security) typically does not need to be changed in order for MERLIN Online to work. |
