Welcome to the Maine GeoLibrary

The Maine Office of GIS had to migrate ownership of the Maine orthoimagery services, which resulted in the removal of OGC WMS services. The WCS is still available, and is now the recommended OGC resource for consuming orthoimagery services in a GIS client. This was an unscheduled change necessitated by a technology update, which is why we were unable to provide advanced notice.
