Ed. note: This article was slightly modified after it was published
to
clarify how the release of ArcGIS 9.3 is being handled by ESRI.
ArcGIS
ArcGIS 9.3 is preceded by a series of service
packs for ArcGIS 9.2
with emphasis on
refining and improving workflows; the bulk of the product is to be
released
next year. ArcGIS
9.3 will include ways to improve "geographic science"
such as using Gaussian geostatistical simulation and rich error
messaging, and
improving mapping and labeling, scripting, modeling, and WYSIWYG
graphic
editing. Below are some of the additions shared during the ESRI User
Conference.
ArcMap
Label placement for contour maps will better match what users of USGS
quad sheets expect. In particular, the contour elevation labels appear
on the major contour intervals and do not overprint the line work. The
new release introduces WYSIWYG editing for line work and improvements
will be made to street number placement, support for Asian language
characters, multiple view windows, labeling on 3D services, the speed
of import of Web services, tracking in 3D, textured COLLADA and schematic
diagramming.
ArcGIS Server
ESRI believes that CIOs are increasingly dealing with GIS and that
server-based GIS is used in most major cities around the world. Key
priorities focus on the high bar set by IT departments, including
systems that are:
- reliable and recoverable
- interoperable and scalable
- highly secure
- deployable to the non-GIS specialist
- printing updates to enhance graphic output, also known as "pretty maps"
- map tips that provide "mouse over" access to attributes
- support for Web Feature Service (WFS), Web Coverage Service (WCS) for raster, Simple Feature KML and GML
- spatial data management and cartographic capabilities for AutoCAD users with the new product "ArcGIS for AutoCAD" which is available now in ArcGIS 9.2
- REST API and Java Script API support
- caching to enhance Web application performance
- security for Web applications and services, allowing users access based on Windows authentication
- support for PostgreSQL, Oracle Express and DB2 (z/OS)
- a mobile client built on the Windows Mobile platform
ArcGIS Explorer is now available and is delivered as a free client with ArcGIS Server.
ArcGIS online, ESRI's Web data repository, continues to grow with more data additions.
Geoprocessing
There will be a number of functionality enhancements to the geoprocessing framework in ArcGIS 9.3.
There will be new business graphs and charts including matrix scatter plots that reveal data characteristics. Scatter plots show slices of different correlations (disposable income, age, ethnicity, race, etc.). The plots are interactive such that each data theme can be selected to graph on a map. A user can select a chart type, draw a box around a group of points on the plot, and have that specific set of data points displayed on the map. Regression analysis will allow users to look at the correlation between data. Users will be able to build a regression model and then apply the model to other geographic areas.
In addition, spatial regression models will allow users to understand how data compare with predicted circumstances or events. If a user determines that certain spatial patterns are not random, there may be some underlying geographic relationships to explore.
The Geographically Weighted Regression Model (GWR) fits a separate regression equation to each data point. It's possible to predict where other phenomena will occur and make comparisons of "before and afterā€¯ sequences of data. For example, banks may want to determine areas where there is a higher probability of foreclosures.
Users will be able to develop geoprocessing tools on their own using Python scripts, ESRI's current scripting language. ESRI is seeking partners to add Python-written models to ArcGIS. Other spatial statistical calculations such as mean distributions, quartile ranges and spatial autocorrelation (Global Moran's I) will also be included.
Real-time modeling
ArcGIS will support building custom solutions to incorporate dynamic displays for real-time events. This visualization will require managing a large number of display objects changing location very quickly.
ArcPad
ArcPad 7.1 (which does not follow the ArcGIS numbering system) includes a street map extension for no additional cost, with data from NAVTEQ. A "quick projectā€¯ tool allows mobile users to immediately begin capturing points, lines and polygons. Categories, basically data themes, can be named and created on the fly. ArcPad 7.1 is in beta now, and will be available in a few months.
Integration with external modeling systems
A new extension will provide a connection between ArcGIS and Clark University's IDRISI software. It will allow access to IDRISI raster tools to perform tasks such as change detection. This new extension should be into beta this week.

| Thanks for the thorough review of 9.3 enhancements. I would like to make one addition however, that being that ESRI is also providing Tele Atlas data for the ArcPad StreetMap extension. Keep up the good work! Bart Guetti Senior Software Engineer Tele Atlas |

| I would like to know, if AJAX will be supported by ArcIMS 9.3 and if you have any comments on new functionalities? Thanks! Dejan Gregor Consultant GISDATA Ljubljana |

| Im curious why certain elements for which solutions had long been got, are just beginning to be integrated into ArcGIS 9.3. Why are we just having Map tips in ArcGIS9.3 while it has been a long while in ArcIMS 4.0, 9.0,9.1 ETC. I welcome solutions that improve interoperability like the improvements in Simple Feature KML and GML workability with ArcGIS. I also welcome the seamless workpath in AutoCAD for ArcGIS. Some GIS Solution providers like Proxy Logics Nigeria, had gone ahead of ESRI to develop applications like ProxyCAD1.1 that work seamlessly with AutoCAD. I think we need ESRI to be more proactive in functionality development. While we wait to see 9.3 some of us believe that the cost of ArcGIS is too much for the industry in developing nations. ArcView which is cheapest in the suite costs about $2000. Now, to think of the fact that a lot of users in these areas use it primarily for mapping and simple analysis, utilizing just a little above 25% of the total functionality provided, methinks that the entire bunch become a waste, I suggest that ESRI should further modularize the ArcView application, take off some more functionalities that are rearly required by minor users and drop the price to between $700-$1000. I thinks it makes more sense and Value for Money for users here. |

| Does anyone have any information or knowledge or how to perform regression analysis between grids in arcGIS 9.2? Any help would be much appreciated. Also, will this be possible in 9.3? Thank You. |

| Is there anybody writing books on python scripting for ArcGIS users? Please let me know My email : tmprasad9@gmail.com |

| What has changed in 3-D Analyst? Are there differences in ArcScene and ArcGlobe? |
