| Abstract: | Object-oriented classification was used to extract water body,vegetation,buildings and road centerline from high resolution remote sensing imageries.The accuracy evaluation results showed that the user accuracy of water body and vegetation was above 90%,the accuracy of buildings and roads was above 70%.Finally,the factors which affect extraction accuracy were analyzed. |
