Arc engine 开发 第8章小结

主要是讲了栅格数据

其中有，访问与创建栅格数据

IWorkspcaceFactory workspaceFactory = new RasterWorkspaceFactoryClass();IWorkspace workspace;

string filePath = @"E:\data\";IRasterWorkspace2 rasterWorkspace;IRasterDataset rasterDataset;rasterWorkspace = workspaceFactory.OpenFromFile(filePath,0) as IRasterWorkspace2;rasteDataset = rasterWorkspce.OpenRasterDataset(@"\NewTiff);IRasterLayer rasterLayer = new RasterLayerCLass();rasterLayer.CreateFromDataset(tasterDataset);

this.axMapControl1.Map.AddLayer(rasterLayer as ILayer);this.axMapControl1.Extent(this.axMapControl1.FUll.Extent;
