USING ARCGIS MODEL BUILDER FOR OBJECT-BASED IMAGE CLASSIFICATION OF SEAGRASS MEADOWS
GIS Mapping Oceanography Vegetation Classification Object Image
2015/8/19
Seagrass meadows are an important coastal habitat serving as a good indicator of healthy coastal ecosystems. Object-based image classification is a new method of seagrass mapping. The goal of the proj...
流域地形指数水文模型TOPMODEL已被应用于陆面模式(Land Surface Models, LSMs)以改进陆面模式对水文过程的模拟。地形指数(ln(α/tanβ))是TOPMODEL的核心，是进行水文分析的重要指标。因此，高效的提取地形指数信息非常重要。本文将淮河流域作为案例区，以地形指数单流向算法为理论基础，利用ArcGIS9的Model Builder建模工具，建立地形指数提取模型。在...
