Since mid-2011, we’ve been working away, developing our new Geocortex Viewer for HTML5 to serve organizations deploying Esri’s ArcGIS Server technology. I’m happy to announce that version 1.0 is now available.

It’s clear Esri users are excited about exploring how to leverage HTML5 and ArcGIS Server.  Because it’s still relatively early in the evolution of the HTML5 standard, we’ve been careful to take an approach that strikes the right balance between delivering powerful functionality today and not overextending what browsers can currently support.

The Geocortex Viewer for HTML5 serves different use cases than our feature-rich web mapping/GIS viewers based on Silverlight and Flex. While its capabilities will grow over time, for the foreseeable future the Geocortex Viewer for HTML5 will serve as a complementary viewer geared towards providing simple, targeted web-mapping applications serving desktop browsers, tablets, and a broad array of mobile devices. It allows you to deliver applications across platforms and devices without having to worry about plugins or building native applications, which is especially applicable to mobile scenarios.

The core framework of the Geocortex Viewer for HTML5 is architected after the Geocortex Viewer for Silverlight (named commands and events, shells, regions, and views, and configuration), and prior Workflows you’ve created should just work.

The Geocortex Viewer for HTML5 has already undergone a number of iterations as part of professional services implementations that started back in October, but version 1.0 is still largely an infrastructure release geared towards workflow-driven mobile apps. Nevertheless, the foundation is all there and we have an aggressive R&D scheduled for the remainder of 2012.

To get started now, Geocortex Essentials customers can download the Geocortex Viewer for HTML5 from the Geocortex Support Center. In addition to documentation and sample code, we’ve also developed a half-day training course; the first is scheduled for May 2nd.

The online Geocortex User Conference (June 6-7) will also offer sessions on HTML5 strategy and development.

Remember, though HTML5 today delivers when applied in the right ways, it remains an emerging standard. If you want to learn more about HTML5 and Esri technology, including when it might make sense for your organization to get started, be sure to visit
