Surveying, Mapping and GIS

I am just now making my way back on the Metro back from the reception at the National Geographic, tacking together some unfiltered notes from earlier in the day- my meeting was punctuated by outside meetings in Alexandria and Fairfax, so I managed to get in about 1.6 sessions, and got back just in time to find that the EPA Q&A session was shut out by the passionate Bern Szukalski.

Nonetheless, I attended the "What's New in ArcGIS Server 9.3" session this morning, hosted by Dave Wrazien.

Dave touched on a number of things slated for release, and which gave me some cause for interest, most notably the new APIs

Some bullet points and excerpts from my notes:

Effort is being made by the Server development team to reduce server roundtrips and traffic, via AJAX requests and the ASP.NET approach

A number of JavaScript enhancements have been made to improve the user experience, with an expanded JavaScript library, providing feedback and visual cues ala Flash and Silverlight, such as informative progress bars, pixel-zoom and fade-in zooms as the next zoom level loads.

In terms of OGC interop, AGS 9.3 features support for:

WMS and SLD: 1.0, 1.1, 1.1.1, 1.3 / ISO19128
WFS 1.1, GML 3.0, WFS-T 1.1
WCS 1.0, 1.1, 1.1.1

The REST and JavaScript APIs are probably the most exciting for me. Here, Dave highlighted integration opportunities for VE, Google, Yahoo and others, along with functionality for basic map display, navigation, querying, geocoding, and geoprocessing. Later on, there was mention that the JavaScript API makes use of the REST endpoints.

With respect to platform support, some of the highlights mentioned were

JDK 5.0
PostgreSQL/PostGIS
DB2 and Z/OS
SQL Server 2008 (to come in a service pack release)

In terms of usability, the aim in 9.3 is for fewer button clicks, enhancements to the web map viewer, streamlined processes and a simplified UI.

Improvements to Server Manager are likewise on the horizon for 9.3, with wizards to simplify:

Access Control
Cache Management

Along with a Mobile Management Console and a Web Map Migration Utility.

Cache Management makes some significant strides, allowing static datasets to be prerendered- and in the Mobile Management Console, improvements driven by user use cases allows opportunity for populating mobile devices with lower server and communications overhead. Additionally, while 9.2 only provided mobile developers with an SDK, 9.3 provides templates and other resources toward jumpstart.
