Using WorldView-1 Stereo Data with or without Ground Control P Automatic DEM Generation
The successful operation of the WorldView-1 satellite has enabled advanced high-accuracy mapping using high-resolution satellite images, with or without the use of ground control points (GCPs). The stereo capability of the WorldView-1 sensor also provides the opportunity to extract high-resolution digital elevation models (DEMs). This article will examine the effectiveness of automatic DEM extr...
متن کاملObject-Based Urban Tree Species Classification Using Bi-Temporal WorldView-2 and WorldView-3 Images
Urban tree species mapping is an important prerequisite to understanding the value of urban vegetation in ecological services. In this study, we explored the potential of bi-temporal WorldView-2 (WV2, acquired on 14 September 2012) and WorldView-3 images (WV3, acquired on 18 October 2014) for identifying five dominant urban tree species with the object-based Support Vector Machine (SVM) and Ran...
متن کاملDigital Elevation Model (DEM) Generation from Stereo Images
Digital elevation model (DEM) generation from stereo images is an effective and economical method in topography mapping. This paper used the stereo pair methodology to generate the digital elevation model (DEM) from PRISM (Panchromatic Remote-Sensing Instrument Satellite) sensor which is onboard of ALOS (Advanced Land Observing Satellite). The pair of forward-backward is used as stereoscopic im...
متن کاملTowards Automated Dem Generation from High Resolution Stereo Satellite Images
High resolution stereo satellite imagery is well suited for the creation of digital surface models (DSM). In this paper, a system for highly automated DSM and orthoimage generation based on CARTOSAT-1 imagery is presented. The proposed system processes photometrically corrected level-1 stereo scenes using the rational polynomial coefficients (RPC) universal sensor model. The RPC are derived fro...
متن کاملWavelet Daubechies (db4) Transform Assessment for WorldView-2 Images Fusion
This article implements a new Web service that offers users the possibility to merge images. Throughout the article three important issues are addressed. First, a Web service is implemented using free software to provide a simple interface for users to interact and request the image-fusion service. The second issue deals with the analysis of the Fast Haar Wavelet Transform (FHWT). The final par...
