ArcGIS 9.2 开发文档更新--especially for Java Engine

    ArcGIS Engine和Server开发文档相比微软MSDN逊色不少，前者经常需要查找AO for VB的帮助，后者不少主题还是空白，开发者对ESRI开发文档是抱怨声不断，好在ESRI开发团队在不停更新与维护，这次更新主要集中在ArcEngine for Java SDK，包括文档和代码段：

• Finding locations with geocoding offers topics detailing the ins and outs of assigning a location to an address. 
• Next is the Geodatabase management section with a multitude of topics discussing such things as How to create new geodatabases, How to query geodatabase objects, How to create a multimodal network dataset, How to check for topology error features in a geodatabase topology, How to convert simple data to a geodatabase, and How to export a dataset to an XML workspace document among other things.
• Key to working with ArcGIS is understanding Geometry and spatial reference. This section includes topics on When do I need to simplify a geometry, Understanding coordinate management in ArcGIS, How to convert between high and low precision spatial references, and many more.
• Geoprocessing puts powerful analysis capabilities at your fingertips. Learn how to access geoprocessing tools and toolboxes, use ArcObjects as an input to a tool, and generate your own custom geoprocessing tool. 
• The Mapping and visualization section deals with--you guessed it--maps, map display, layers, page layouts, symbols, renderers, and more.

    除此之外，还有其他内容更新，how to leverage the schema cache，介绍了如何最好的使用AO应用中的schema cache，对schema缓存可以减少geodatabase空间数据库来回访问次数，提高应用效率。Overview of ArcGIS Server application performance tuning更新了ArcGIS Server性能调优方法。

    以往文档更新一般会随着软件下一版本一起释放出来，这次提前将文档推出了，不过还需要继续完善，希望9.3release版本能看到比较大的变化。
