EDN: ESRI Developer Network

Over the last few months the Java Engine team has been feverishly producing over 200 new help topics, most of which include code snippets. Since these topics are applicable to 9.2 we've decided to publish them now rather than waiting to deliver them with the next software release. You can find the topics in a new ArcObjects Developer Guide section within the Building cross-platform solutions with ArcGIS Engine using Java book in the EDN Documentation Library. The topics are grouped into a number of sub-sections that focus on different areas of the ArcGIS architecture. These include:

• 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.

As an added bonus, each of these new topics also includes the comment feature! You can use it to ask for additional clarification on the topic, offer suggestions for other related topics of discussion, or provide your own expertise in that area to the Java community at large.
