| description | The latest technology of high resolution satellite imagery has provided its metric potential for mapping. Quickbird imaging systems offer ortho-image products which comply with the specification of map accuracy for scales as large as 1:10,000. This study is to determine the ability of Quickbird satellite imagery to be used for topographic detail mapping. In this study, the systematic procedure and the suitable technique to extract ground features from Quickbird data were carried out. The procedure includes the Digital Elevation Model (DEM) extraction to remove the relief displacement of the Quickbird image. The DEM was extracted using scanned aerial photograph and processed by stereo correlation technique. Visual interpretation technique was used to extract the point features, while the Edge Detector filters to extract the linear features. In order to extract polygon features, Canny Filter and Region Growing Segmentation were used. The accuracy of the results comprises of Root Mean Square Error (RMSE). In this study, the accuracy of the topographic detail plan derived from Quickbird image is 3.1068 meters, which fulfill requirement mapping of 1:1,000 scales. This leads to conclusion that Quickbird image can be used as a data source for topographic detail mapping. |
