What is "arcims"

ArcIMS (standing for Arc Internet Map Server) is a Web Map Server produced by Esri accessible through a web browser. It is a GIS that is designed to serve maps across the Internet. Sometimes these maps are just static images allowing simple panning and zooming, while others are more complex pages. Examples of interactive maps served with ArcIMS include maps with layers that can be turned on and off, or with features containing attributes that can be queried.
