With the advance of web mapping services and Web technology, creating and publishing high-performing, modern-looking Web maps has become easier and rich with options. This workshop teaches the basics of how to build attractive, sophisticated internet mapping applications using the lightweight, browser based ArcGIS Server JavaScript API. Topics include designing and publishing web mapping services using ArcGIS Server; consuming ArcGIS map services using the ArcGIS Server REST API and Dojo Javascript library; integrating functionality (queries, geoprocessing, etc.) for more interactive applications; and tools and techniques for rapid application development. This Workshop is geared toward GIS analysts and others who want to create rich internet mapping applications to publish GIS content throughout an organization or to the public via the Internet.
