mapx 单位问题！
miUnitMeter 这个代表什么？是米吗？哪位高手告诉一下！

------解决方案--------------------

C/C++ code

enum MapUnitConstants{    miUnitMile = 0,    miUnitKilometer = 1,    miUnitInch = 2,    miUnitFoot = 3,    miUnitYard = 4,    miUnitMillimeter = 5,    miUnitCentimeter = 6,    miUnitMeter = 7,    //应该是米，因为前面有千米 厘米什么的了。    miUnitSurveyFoot = 8,    miUnitNauticalMile = 9,    miUnitTwip = 10,    miUnitPoint = 11,    miUnitPica = 12,    miUnitDegree = 13,    miUnitLink = 30,    miUnitChain = 31,    miUnitRod = 32};

不是米是啥，但是不要和默认的单位Mile英里混了！
