Digital map of the state (political) boundaries of Mexico

This data set represents the state (political) boundaries of Mexico. The Digitial Chart of the World data set had incomplete state boundaries, which was the reason to create this coverage. It was digitized from a 1992 CIA map at a scale of 1:3 million. The coast line came from the Digital Chart of the world at a scale of 1:1 million. The state names were labeled from the map and an attribute to help fill the states was added. The labeling process was done manually.本数据集呈现墨西哥的政治州界。此前的世界数字海图（Digital Chart of the World）数据集存在州界信息不完整的问题，这正是本数据集编制的动因。本数据集基于1992年美国中央情报局（CIA）发布的比例尺为1:300万的地图完成数字化处理。其海岸线数据取自比例尺为1:100万的世界数字海图数据集。州名均从原地图中手动标注提取，并额外增设了用于辅助填充州域的属性字段。全部标注流程均采用手工完成。
