[转]在 Eclipse 中嵌入 NASA World Wind Java SDK

与 WWJ 捆绑的数据集

WWJ 捆绑了以下低、中和高分辨率的数据集（参见 参考资料，获取它们的链接）：

• Blue Marble (分辨率：1 千米/像素)
• i-cubed Landsat 7 (分辨率：15 米/像素)，来自马里兰大学高级计算机研究所的 Global Land Cover Facility
• 海拔数据（源自 SRTM30Plus/SRTMv2/USGS NED 的数据集），来自 NASA 喷气推进实验室
• USGS 地形图、黑白垂直图像和彩色市区图像，由 USGS 和 Microsoft® 研究
• 美国地名，来自 USGS 地理名称信息系统
• 世界地名，来自美国国家地理空间情报局
