True Ortho-photo Generation from High Resolution Satellite Imagery
Ortho-photos provide valuable spatial and spectral information for various GIS and mapping applications. The absence of relief displacement and the uniform scale in ortho-photos enable interested users to measure distances, compute areas, derive geographic locations, and quantify changes. Differential rectification has traditionally been used for ortho-photo generation. However, differential re...
متن کاملOrthorectification of High Resolution Satellite Images
The growing availability of high resolution satellite images leads to evaluations that are aimed at the definition of the mapping scale they can reasonably be defined for. The problems connected to the use of satellite images for the production of orthophotos in urban areas at a middle scale are dealt with in this work. An analysis of the residuals perspective errors connected to the presence o...
متن کاملMapping Coastal Ecosystems of an Offshore Landfill Island Using Worldview-2 High Resolution Satellite Imagery
* Corresponding author. Abstract – The Worldview-2 satellite imagery with 2-m spatial resolution and 8 spectral bands is used to map the coastal ecosystems for our study site, an offshore island of Singapore. The eastern side of the study area is used as a landfill, while the western part of the island is left natural with rich biodiversity where large stretches of seagrass meadow, mangroves an...
متن کاملComparison of Different Algorithms to Orthorectify WorldView-2 Satellite Imagery
Due to their level of spatial detail (pixel dimensions equal to or less than 1 m), very high-resolution satellite images (VHRSIs) need particular georeferencing and geometric corrections which require careful orthorectification. Although there are several dedicated algorithms, mainly commercial and free software for geographic information system (GIS) and remote sensing applications, the qualit...
متن کاملApplication of Different Pan-sharpening Methods on Worldview-3 Images
In the field of the remote sensing, the introduction of high resolution satellite sensors has required the development of several data fusion approaches. Two kinds of images are usually acquired: multispectral and panchromatic. The first group has a lower spatial resolution but accurate spectral information while the second presents a higher spatial resolution with a longer band acquisition ran...
