FeatureDataset:要素数据集,放置着相同空间参考的要素类。 先看官方解释:A FeatureDataset is a container for feature classes that share the same spatial refrence. 要素数据集对象在GeoDatabase是一个简单的要素类的容器,在这个容器内放置着相同空间参考的要素类。 FeatureClass:是用来存储空间数据的对象类,是Objec...
Feature classes 存储了简单的要素，他可以在featureDataset内也可以在dataet外，在外面的featureclass被称作独立的 featureclass。存储了拓扑关系的featureclass必须包含在dataset中以确保他们是统一的空间索引（spatial reference）。一个 FeatureDataset是一个仅存在于geodatabase工作空间的dataset。他的所有datase...

This article shows how feature classes are created within a feature dataset and how to create empty feature classes, into which features can be loaded or created. The decision to create a feature class either in a feature dataset or as a stand-alone feature class depends on the purpose of ...

An apparatus comprises feature dataset input circuitry to receive a feature dataset comprising multiple feature data values indicative of a set of features, wherein each feature data value is represented by a set of bits. Class retrieval circuitry is responsive to reception of the feature dataset ...
In hyperspectral image classification, higher dimensionality of data could improve the capability of class detection as well as distinguish different classes with better accuracy. The method calculation of ICA is a transforming a random vector into another space which consists of independent components. ...
1.通过IWorkspace的Datasets属性获取工作空间中的所有Dataset对象(IEnumDataset) 2.枚举EnumDataset,获取Dataset对象 3.如果该Dataset是FeatureDataset 4.QI到IFeatureClassContainer接口 for(int i=0;i < pFClContainer.ClassCount;i++) { IFeatureClass pFeatureClass= pFClContainer.Class(i); ...
