Center point matching network based on multi-coverage templates for high-resolution satellite orthorectification

KSCE Journal of Civil Engineering
High-resolution (HR) satellite images are provided with rational polynomial coefficients (RPCs) that map ground coordinates to image space. However, initial RPCs are derived from approximate models and contain geometric errors.

Lidar and true-orthorectification of infrared aerial imagery of high Pinus sylvestris forest in mountainous relief [PDF]

, 2008
Combination of various data sources has been demonstrated more effective than using them separately. Information retrieval is significantly improved by synergies between laser scanner and optical imagery. Digital photography relies on traditional methods

Study of the methods of satellite images orthorectification [PDF]

, 2016
В статті розглянуто етапи корекції космічних знімків від первісного («сирого») зображення до орторектифікованого (аналог ортофотоплану). Наведено опис проведення ректифікації зображення. Проаналізовано існуючі геометричні моделі орторектифікації.

A new rigorous model for the orthorectification of syncronous and asyncronous high resolution imagery

, 2005
This paper proposes a new rigorous model for the orthorectification of high resolution imagery. Firstly, the model was developed and tested in the most general situation, that is considering the asynchronous EROS A satellite; now it is under extension in

GPU Acceleration for SAR Satellite Image Ortho-Rectification

Remote Sensing
Synthetic Aperture Radar (SAR) satellite image ortho-rectification requires pixel-level calculations, which are time-consuming. Moreover, for SAR images with large overlapping areas, the processing time for ortho-rectification increases linearly ...

A frequency-based approach to improve the geometric accuracy of FY4B/AGRI geostationary satellite observations

Science of Remote Sensing
The Advanced Geostationary Radiation Imager (AGRI) onboard the FengYun-4B (FY4B) satellite—a new-generation geostationary (GEO) platform—offers spatial and radiometric resolutions comparable to those of polar-orbiting satellites such as EOS-MODIS, but ...

Comparison of orthorectification methods suitable for rapid mapping using direct georeferencing and RPC for optical satellite data [PDF]

, 2008
One of the first essential steps in response to a crisis event is to provide current, precise, and rapid information about the extent of the event, the affected population and infrastructure (e.g., information for relief teams).

Calibration Method for Aerial Vehicles

, 2011
Aerial vehicles make good remote sensing platforms by reducing the cost and making imagery easier to obtain. The low altitude, small image footprint and high number of images make it difficult and tedious to georeference the images based on features ...
