ArcGIS Desktop 9.3
Modeling and Analysis
ArcGIS Desktop 9.3 delivers a number of enhancements and new features that improve geographic data modelling and analysis, including:
- The new, advanced Ordinary Least Squares and Geographically Weighted Regression tools help you understand how processes vary over space.
- Geoprocessing error messages are improved and now let you hyperlink to a full description of the problem. The geoprocessing progress bar gives a better indication of current status.
- Python scripts can be run in process, significantly reducing execution time.
- A new scatterplot matrix graph lets you explore relationships between sets of related variables.
- The Near tool has been improved to work with points, lines, and polygons and can find multiple feature classes.
- The new, advanced Ordinary Least Squares and Geographically Weighted Regression tools help you understand how processes vary over space.
- New tools to create spatial weights matrices show spatial relationships in feature classes and network datasets.
- Buffer tool improvements include support for geodesic buffers and better performance.
- Geostatistical functions like kriging can now take advantage of multiple CPUs.
- Viewshed, inverse distance weighting (IDW), and Combine functions now work with very large input datasets.
- A new vehicle routing problem (VRP) solver in ArcGIS Network Analyst generates routes for fleets of vehicles.
