ArcGIS空间关系：ArcEngine中的esriSpatialRelEnum枚举
本文从ArcGIS空间查询接口，本文偏应用，主要介绍ArcEngine枚举esriSpatialRelEnum，从ISpatialFilter的SpatialRel属性来介绍
esriSpatialRelEnum枚举
| 序号 | 项 | 英文描述 | 中文描述 |
|---|---|---|---|
| 1 | esriSpatialRelUndefined | No Defined Spatial Relationship. | 没有定义的空间关系 |
| 2 | esriSpatialRelIntersects | Query Geometry Intersects Target Geometry. | 查询几何体与目标几何体相交 |
| 3 | esriSpatialRelEnvelopeIntersects | Envelope of Query Geometry Intersects Envelope of Target Geometry. | 查询几何体的包络线与目标几何体的包络线相交。 |
| 4 | esriSpatialRelIndexIntersects | Query Geometry Intersects Index entry for Target Geometry (Primary Index Filter). | 查询几何体与目标几何体的索引项相交（主索引筛选器） |
| 5 | esriSpatialRelTouches | Query Geometry Touches Target Geometry. | 查询几何体接触目标几何体。 |
| 6 | esriSpatialRelOverlaps | Query Geometry Overlaps Target Geometry. | 查询几何体与目标几何体重叠。 |
| 7 | esriSpatialRelCrosses | Query Geometry Crosses Target Geometry. | 查询几何体与目标几何体相交。 |
| 8 | esriSpatialRelWithin | Query Geometry is Within Target Geometry. | 查询几何体在目标几何体中。 |
| 9 | esriSpatialRelContains | Query Geometry Contains Target Geometry. | 查询几何体在目标几何体中。 |
| 10 | esriSpatialRelRelation | Query geometry IBE(Interior-Boundary-Exterior) relationship with target geometry. | 查询几何体IBE（内边界-外部）与目标几何体的关系。 |
1.组织测试数据以及案例Demo
1.1 测试数据如下
1查询图形
2目标查询图形
1.2 为了方便查看最后结论，先贴一下结果图
