With very high resolution satellite (VHRS) imagery of 0.5 m, WorldView-2 (WV02) satellite images have been widely used in the field of surveying and mapping. However, for the specific WV02 satellite image geometric orientation model, there is a lack of detailed research and explanation. This paper elaborates the construction process of the WV02 satellite rigorous sensor model (RSM), which consi...

Establishing the ground control point (GCP) network is a pre-requisite for georeferencing raw image data. Given current typical digital spatial database quality, much interest among users is about the accuracy of the geometric correction model that yields the final product. This paper reports an approach to optimizing GCP assembly using a genetic/evolution algorithm. The paper also suggests an ...

With the development of space technology and the performance of remote sensors, high-resolution satellites are continuously launched by countries around the world. Due to high efficiency, large coverage and not being limited by the spatial regulation, satellite imagery becomes one of the important means to acquire geospatial information. This paper explores geometric processing using satellite ...

Ground control point (GCP) extraction is an essential step in automatic registration of remote sensing images. However the lack of quantitative and objective methods for analyzing the GCP quality becomes the bottleneck that prevents the broad development of automatic image registration. Although several measurements for evaluating the number, accuracy and distribution of GCPs have been proposed...

As one way of removing the requirement of ground control points (GCPs) for precise mapping of high resolution satellite images (HRSIs), this paper proposes to use existing low-resolution elevation dataset. We adapted DEM matching technique, originally proposed to solve absolute orientation of aerial images from perspective sensors, for establishing absolute orientation of HRSIs from pushbroom s...

SPOT images are one of the most widely used satellite images in middle scale mapping applications for its stereo capability, wide coverage area and well-known satellite model which is supported nearly in all photogrammetric software. Stereoscopic imaging capability of SPOT allows generating digital elevation models (DEM) from a pair of overlapping images. DEMs based on satellite images are esse...

Traditional aerial-triangulation has long relied on control points orientating the photo models into a ground-based coordinate system, reducing the distortion effect when tying photos by imperfect photo measurements, and calibrating camera inner parameters. Field surveying preparing for adequate number of control points and manual measurements of the control points afterwards on the photos cost...

Compensating for distortions in pushbroom satellite imagery has a bearing on subsequent earth observation applications. Traditional distortion correction methods usually depend on ground control points (GCPs) acquired from a high-accuracy geometric calibration field (GCF). Due to the high construction costs and site constraints of GCF, it is difficult to perform distortion detection regularly. ...

Synthetic Aperture Radar (SAR) is a microwave remote sensing sensor, which can be mounted either on spaceborne or airborne systems and allows night and day and all-weather imaging. Use of interferometric SAR systems (which consist of two SAR antennas pointing to the same area from slightly different view angles) allows the generation of Digital Elevation Models (DEMs) by means of the so-called ...
