<static> doAnalysis(target, pointCollection, ignoreHeight, count)

根据用户的目标点和被搜索点集合，计算返回离目标点最近的点

Parameters:

Name	Type	Default	Description
target	Object
pointCollection	Array.<Object>		被搜索点集合，Object格式为{location: {lon: xxx.xx, lat: xxx.xx, height: xx.xx}, properties: {xx:xx, yy: yy ...}}
ignoreHeight	Boolean	true	如果为true则计算距离时忽略高程,默认为true
count	Number	1	返回个数，默认为1

Returns:

返回最近的几个点，个数由count参数决定，Object格式为{ distance: xx, point: { location: { lon: xxx.xx, lat: xxx.xx, height: xx.xx }, properties: { xx:xx, yy: yy ... } } }

Type

Array.<Object>
