User expectations for web mapping applications have changed dramatically in the past few years thanks largely to Google Maps and Microsoft Virtual Earth technologies which brought “Web 2.0” to the masses and forever changed our expectations of how these applications should look, perform, and access data. With the advent of “Web 2.0” your applications must meet certain expectations including sleek interface controls, a better user experience driven largely by asynchronous data processing and client-side scripting, drag and drop capabilities, and the ability to combine or “mashup” multiple data sources into a single application. A number of JavaScript toolkits including Dojo, jQuery, Yui, Mochikit, and many others have been developed to enable these capabilities. ESRI recently released the JavaScript API for ArcGIS Server which was built on top of the Dojo toolkit and enables developers to take advantage of the capabilities provided by this JavaScript toolkit. Dojo is also a highly flexible toolkit that allows you to pick and choose the pieces of the toolkit that best fit your needs. According to Jayant Sai of ESRI, “We like the fact that our users can use the whole Dojo toolkit to build their next generation web 2.0 mapping application, or use just our mapping components, without really getting into the hardcore JavaScript pieces of the toolkit.”
Today we are starting a series of posts concentrating on the use of Dojo for building web mapping applications. We’ll not only examine how Dojo is used with theArcGIS Server JavaScript API, but you’ll also see how you can use this toolkit with other mapping API’s including Google Maps. We’ll start with a simple overview of Dojo and how it can be used in your web based GIS applications. [...]
