json转换问题，求解求搭救。。。。。。。。。

[
{
wFrom: {
fLatitude: "114.057868",
fLongitude: "22.543099",
fName: "深圳市"
},
wTo: {
tLatitude: "37.6173",
tLongitude: "55.755826",
tName: "Moscow"
},
wValue: "31",
wkey: "深圳市",
wproperties: "bag"
},
{
wFrom: {
fLatitude: "116.681972",
fLongitude: "23.354091",
fName: "汕头市"
},
wTo: {
tLatitude: "37.6173",
tLongitude: "55.755826",
tName: "Moscow"
},
wValue: "24",
wkey: "汕头市",
wproperties: "Baby Toys"
}
];
上面个数组怎么遍历构造出下面这种结构的数据：
var geodata = { "Moscow":[37.6173,55.755826],
"深圳市":[114.057868,22.543099],
"汕头市":[116.681972,23.354091] };
求高手指点啊
