缓冲区分析;<br/>
支持点几何、多点几何、线几何、多线几何、区几何、多区几何、矩形几何、圆形几何或任意几何组成的几何数组;<br/>
忽略三维高度，当geometry为几何数组时，其子元素的坐标系必须相同;<br/>
如果distance是数字，则可以为正值或负值，是正值则向外扩张，是负值，则表示向内收缩;<br/>
如果distance是数字，且geometry为几何数组，则该数字会应用到所有geometry数组的子元素;<br/>
如果distance是数组且geometry是数组，当distance的长度小于geometry数组的长度时，会以distance的最后一个子元素扩充distance数组，使其长度和geometry数组的长度相同，之后将distance数组和geometry数组根据下标一一对应，执行缓冲区分析;<br/>
如果distance是数组，但geometry不是数组，则使distance数组的第一个子元素做为缓冲距离来执行缓冲区分析;<br/>
注意一个或多个几何执行缓冲区分析后，由于缓冲后几何扩大，可能导致一个或多个几何出现重合的情况;;<br/>
示例如下：<br/>
<a href='#buffer1'>[1、区缓冲分析]</a><br/>
<a href='#buffer2'>[2、多区缓冲分析]</a><br/>
<a href='#buffer3'>[3、几何数组缓冲区分析]</a><br/>

判断containerGeometry对象是否完全包含insideGeometry对象;<br/>
忽略三维高度;<br/>
支持自定义坐标系的几何对象，几何的坐标系必须相同;<br/>
包含标准如下：
点包含点的标准为：两个点几何坐标是否相等;<br/>
线包含线的标准为：一条线上的点都在另一条线上，或两条线的点坐标相同;<br/>
区包含线的标准为：线在区几何内，但线不全部在区几何边线上(包括内圈和外圈的边线);<br/>
区包含线的标准为：点在区几何内，不在边线上(包括内圈和外圈的边线);<br/>
区包含区的标准为：一个区在另一个区内(如果有带洞区域，则不能在带洞区域内，可以挨着边线)，边线可以重合;<br/>
其他情况为上述标准的组合;<br/>
由于包含的情况太多，这里仅列举部分示例，示例如下：<br/>
<a href='#intersects1'>[1、区包含点]</a><br/>
<a href='#intersects2'>[2、多点包含点]</a><br/>
<a href='#intersects3'>[3、区包含线]</a><br/>

判断一个几何对象是否穿过另一个几何对象;<br/>
要穿过的几何类型为：线、多线，忽略三维高度;<br/>
被穿过的几何类型为：线、多线、矩形、圆、区以及多区，忽略三维高度，穿线和被穿过几何的坐标系必须相同;<br/>
要穿过的几何与被穿过的几何（geometry1和geometry2）可以调换输入，但其中一个geometry必须是LineString、MultiLineString中的一类;<br/>
当被穿过的几何类型为MultiLineString、MultiPolygon时，只要MultiLineString和MultiPolygon中有一个要素被穿过，就算穿过，返回true;<br/>
当要穿过的几何类型为MultiLineString时，只要MultiLineString中有一条线穿过geometry2（被穿过的几何体），就算穿过，返回true;<br/>
如果两条线出现重叠，此种情况不算穿过，返回false;<br/
如果两条线出现“入”型、“L”型，此种情况不算穿过，返回false;<br/>
线与圆相切的情况不算穿过，返回false;<br/>
线和多边形的一条边重叠，算穿过，返回true;<br/>
当polygon有内圈时，只要穿过外圈就算穿过，返回true;<br/>

<p><a id='cut'></a>
使用一条线来切割几何，将其分割为多个几何对象;<br/>
被切割的几何类型为：线、多线、区以及多区，忽略三维高度，切线和被切割几何的坐标系必须相同;<br/>
此接口不会像arcgis的geometryEngine.cut方法那样，返回切割线左右两边的几何对象数组，而是把所有的被切割好的几何组成一个数组并返回;<br/>
如果切割线和被切割几何没有相交，则会返回一个空数组;<br/>
线切割线会返回被切割后的线几何数组;<br/>
线切割多线仅会返回被切割后的线几何数组，如果多线中的某一个线段不与切割线相交，则不会返回该线段几何;<br/>
线切割区会返回被切割后的区几何数组，如果切线仅仅是部分和区相交，但是没有穿过几何，会返回一个仅包含该区几何对像的数组;<br/>
线切割多区仅会返回被切割后的区几何数组，如果多区中的某一个区不与切割线相交，则不会返回该区几何;<br/>
示例如下：<br/>
<a href='#cut1'>[1、线切割线]</a><br/>
<a href='#cut2'>[2、线切割多线]</a><br/>
<a href='#cut3'>[3、线切割区]</a><br/>

对几何对象进行拓扑检查;<br/>
支持的几何类型为线、多线、区和多区，支持任意坐标系几何，忽略三维高度;<br/>
线类型的标准为：1、自身的非相邻线段不会自相交(两个线段仅有一个端点重叠不算相交)；2、线自身的线段不会重叠;<br/>
多线类型的标准为：1、自身的子线段必须是拓扑正确的；2、子线段不会相交;<br/>
区类型的标准为：1、外圈和内圈满足线类型的拓扑检查标准；2、外圈和内圈、内圈和内圈不会相交；3、内圈不会超过外圈;<br/>
多区类型的标准为：1、自身的子区必须是拓扑正确的；2、子区不会相交;<br/>

判断一个几何对象是否和另一个几何对象相邻
被测试相邻关系的几何类型为：线、多线、矩形、圆、区以及多区，忽略三维高度;<br/>
用来测试相邻关系的几何类型为：点、多点、线、多线、矩形、圆、区以及多区，忽略三维高度，穿线和被穿过几何的坐标系必须相同;<br/>
线和点相邻的标准为：点在线的两端，且线不是头尾闭合的;<br/>
对于multi类型的几何（如多点、多线、多区）,无论其和任何其他支持的几何类型判断touch，只要multi中的一个与另一个geometry有包含关系、相交关系，touch即为false;<br/>
对于区、线、圆、矩形和多点判断相邻关系时，只有有一个点在区内、线上、矩形内、圆内，touch即为false;<br/>
