WorldWind Series 15: How to cut image and DEM data and its application configuration in WW

WorldWind Learning Series 14 I analyze how to load DEM data from the code, which involves the algorithm, which has learning and reference meaning. But for the application or to say is anxious for the netizen, the practical value is not too big! Our analysis of code is a learning process, not a goal, after all, to fall on how to apply their own image and DEM data, how to develop based on their own data to meet their own project requirements of the new WW Plug-ins. This is a process that needs to be step-by-step, just to share with you today how to cut your own image or DEM, and how to set the appropriate XML configuration.

My study and practice, mainly refer to Http://worldwindcentral.com/wiki/Dstile_howto, for good English users, suggest reading the original, anyway, my English is not very good, combined with practice, I almost read the original five or six times. My following is the translation part and my own practice steps and experience (will be in the red Word part).

This is a document that teaches you how to add your own geographic reference image data to WorldWind in a step-by-step way. The Help document will show you how to cut the image data into tiles and how to create layers using these tile data in WW. At this point, you can publish the layer as a add-on plug-in. This layer can be completely placed on your computer. If you want to make tile data available to others as a publishing service, the document may not help you.

The organization of the WW Tile system is as follows:

Before you read the following, make sure you understand how the WW tile works and how the XML is configured in the diagram above. (Note: The image above is WW's essence)

Below I will take you to create a layer instance where the data can be exchanged for your own. (Note: First practice, it is recommended that you use the same data the same steps, the whole process to go through)
