MicroStation与ArcGIS协同的解决方案

总体技术路线:

一,采用MicroStation作为制图和三维显示的前端;

二,采用ArcSde+Oralce Spatial进行空间数据库管理

三,采用ArcEngine开发标准WebService实现MicroStation和ArcSde空间数据引擎的交互接口

先分析下:MicroStation的主要要素类型                                              ArcGIS.IGeometry对象

Point3d         点                                                                             IPoint                        点要素(支持x,y,z)

PointString    点串                                                                          MultiPoints                 多点要素

Line              直线                                                                          ISegment(ILine)         ILine类型                 

LineString     线串                                                                           应该是IPath

ComplexString   复杂链                                                                   IPolyLine

Arc               弧段(圆或者椭圆)                                                          ISegment(ICircleArc/IEllipseArc)  

Curve           曲线                                                              利用节点拟合

Shape           直线构成的多边形                                            只有一个所有ISegment都是ILine的IRing的Polygon

ComplexShpae    由直线,曲线,弧段等多种线形组成的复杂多边形   只有一个IRing的Polygon

CellHeader           开孔多边形或者多唤多边形                                       多环的Polygon
