The Advanced Land Observing Satellite (ALOS) was launched on Jan 24th, 2006 by a Japan Aerospace Exploration Agency (JAXA) H-IIA launcher. It carries three remote sensing instruments: Advanced Visible and Near Infrared Radiometer type-2 (AVNIR-2), Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) and Phased Array Type L-band Synthetic Aperture Radar (PALSAR). Within the framewor...

A very important factor in the assessment of solar energy resources is the availability of direct irradiance data of high quality. However, this component of solar radiation is seldom measured and thus must be estimated from data of global solar irradiance, which is registered in most radiometric stations. In recent years, artificial neural networks (ANN) have shown to be a powerful tool for ma...

Last advances in sensors, photogrammetry and computer vision have led to high-automation levels of 3D reconstruction processes for generating dense models and multispectral orthoimages from Unmanned Aerial Vehicle (UAV) images. However, these cartographic products are sometimes blurred and degraded due to sun reflection effects which reduce the image contrast and colour fidelity in photogrammet...

This paper describes a scalable software system that can synthesize radiometri-cally accurate images.

high-resolution imagery such as ikonos satellite can produce useful information for many resource management applications. we investigated the capability of pan and multi spectral ikonos imagery of one region of tehran dated from 2005 in urban vegetation management and mapping of green cover. after data quality of images for radiometric noises, the images were geometrically corrected by polynom...

Radiometric consistency of multi-temporal satellite observations is affected by sensor stability and scene related issues. Relative radiometric normalization (RRN) a widely-used method to reduce these differences, its performance depends on the accurate identification representative pseudo-invariant features (PIFs). However, existing RRN methods are mainly developed for bi-temporal images limit...

Determination of reliable crystallization ages by K-Ar methods for young (<1 Ma), fresh basalts from the seafloor has been frustrated by several effects. The small amounts of radiogenic 4øAr developed over these timescales in such 10w-K rocks are difficult to resolve from predominantly atmospheric 4øAr. An additional concern is that mantle-derived 4øAr may not be totally outgassed when magmas q...
