Feature type
Real-world object or concept
esriFTSimple Polygons, polylines, and points representing objects or places that have area, such as water bodies; linear objects, such as rivers; and localized positions, such as houses or sample sites.
esriFTSimpleJunction Simple junction feature in a geometric network representing point objects, such as a fuse, service point, or telephone pole.
esriFTSimpleEdge Simple edge feature in a geometric network representing polyline objects, such as primary or secondary overheads.
esriFTComplexJunction Complex junction feature in a geometric network, not in general use.
esriFTComplexEdge Complex edge feature in a geometric network representing polyline objects such as primary overheads, which have midspan connectivity. Network resources flow through complex edge without interruption by midspan connectivity.

ArcGis 创建Annotation注记要素类、添加注记要素 并加载到Activeview AO C#

AO中一般有两种方式存储图面注记元素，一种使用TextElement，它是文档级的元素，编辑后要通过文档（mxd）保存；另一种是使用Annotation要素类，它是一个独立的要素类（featureclass），需要存储到地理数据库中。使用Annotation featureclass 的方式更灵活、更强大，至于如何灵活，如何强大，待你用到便自知。 1、创建一个标准的Annotation...
