For over a decade, EA has provided hosting and support services for multiple, web-based Environmental Information Management Systems (EIMS) for the Maryland Department of Transportation (MDOT) and its individual Transportation Business Units.  EA maintains a secure, high performance hosting environment for the EIMSs on-premise where our industry certified and trained staff of Network Engineers and Server Administrators monitor and administer the environment. Additionally, EA provides dedicated email and phone help desk support for the hundreds of users of the EIMS, quickly responding to support requests through a combination of step-by-step instructions, back-end data updates, or system patches.
