• E00格式的DCW数据转化为SHP格式
• 其它坐标系的USSR 和Antarctica的样板数据，从DCW数据转换为WGS 1984格式
• 依据最近十五年的地理信息来制定相应的国界信息，比如巴西的部分区域，捷克共和国和斯洛伐克的分隔区域，以及从印尼独立出来的东蒂汶区域等
• 增加了世界地图的边界、国家和国家名称、首都城市、主要水系等。从DCW文件针对每一个国家进行组织
• 您可以无限制得使用该数据集，并可以免费将其应用于任何由DK toolkit编制的TatukGIS产品和程序中

The following customization was performed to the original DCW dataset:

• DCW data converted from the E00 format to the SHP format
• Data for the former USSR and Antarctica converted from other coordinate systems in the DCW dataset to WGS 1984.
• Country boarders updated to reflect geopolitical changes during the last fifteen years, e.g., the creation of countries in the Balkan region, separation of the Czech Republic and Slovakia, creation of East Timor from Indonesia, etc.
• Addition of a top view world map layer with country boarders, country and continent names, capital cities, major bodies of water, etc. created from the DCW files for each country.
• The use of this dataset is unrestricted and can be freely deployed with any TatukGIS product or application created from the DK toolkit.
