Abstract: 

Nowadays, to obtain information covering urban land, the city is one of the most important and widely used management tools in the study of Earth changes. Classification of images is one of the most common methods of extracting information from remote sensing data. Complex and dense urban areas are one of the problems in the analysis of remote sensing. The accuracy of classification performance in these areas is under the attention of the researchers and always tries to improve the accuracy. Using different data and application integration techniques to classify a variety of effects can be more accurate-achieved with higher reliability. Among the successful classification methods in recent years, support vector machines algorithm and ensemble learning algorithms such as Bagging, Boosting and Random Forest noted can be mentioned. In this paper, the performance of the four algorithms to identify the effects of the dense city with a very high resolution aerial LIDAR and image are discussed. The results show that the combination of LIDAR data and aerial image, gives out a better classification of the degree of urban features. The classification of urban features with the help of integrated LIDAR and aerial image information with the use of support vector machine algorithm-precision 93.99% performs higher ability than other classification methods such as Bagging, Boosting and Random Forest.
