Abstract
Modernizing the HTML Map Viewer Track: Application Development Author(s): John Cartwright NOAA's National Geophysical Data Center (NGDC) hosts more than 40 map services and viewers. The viewers are based on the ArcIMS HTML Viewer template, and while all they all share a common look-and-feel, most incorporate custom tools and programming specific to that viewer. The template upon which all this work was originally based is fundamentally unchanged from the days of the "browser wars". It makes significant efforts to accommodate now obsolete browsers, and does not fully take advantage of the standards support that modern browsers provide. In an effort to streamline the code and make the template easier to maintain and modify, NGDC has undertaken to modernize the viewer using CSS and AJAX. The work leverages open-source Javascript libraries as well as in-house classes built to encapsulate elements of the AXL requests and responses. The second phase of this project involves the migration of the business logic to the server while maintaining the browser-based user interface.
