With ArcGIS REST API Map Service, users can access content of a map hosted on a server. The site offers visual displays with updates, resource hierarchy, request parameters, and JSON response examples. This mapping service could be useful if developers intent to access functions such as dynamic drawing, query, and search through the server ArcGIS. If they decide to use the map service root URL, they will find network analysis and vector editing tools. More information available via e-mail, forum, and social media.
