In March, 2016 we first completed the global data processing of digital surface models (DSMs) by using the whole archives of stereo images derived from the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) onboard the Advanced Land Observing Satellite (ALOS). The dataset has unprecedented 5 m grid spacing utilizing the original stereo images in 2.5 m resolution while its target accuracy...
A new global digital surface model (DSM) dataset using the archived data of the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) onboard the Advanced Land Observing Satellite (ALOS) has been completed on March 2016 by Japan Aerospace Exploration Agency (JAXA) collaborating with NTT DATA Corp. and Remote Sensing Technology Center, Japan. This project calls “ALOS World 3D” (AW3D), and...
One of the fundamental issues in the generation of digital surface models (DSMs) from optical stereo imageries is the noise reduction on the low correlation areas. We apply the non-local means filtering to the DSM derived from Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) onboard Advanced Land Observing Satellite (ALOS) with modifying the original algorithm so that it can appropriately...
Panchromatic Remote-sensing Instrument for Stereo Mapping, one of onboard sensors carried by Advanced Land Observing Satellite, was designed to generate worldwide topographic data with its optical stereoscopic observation. It has an exclusive ability to perform a triplet stereo observation along its track, and collected its derived images all over the world during the mission life of the satellite...
The Japan Aerospace Exploration Agency is generating the global digital elevation/surface model (DEM/DSM) and ortho-rectified image (ORI) using the archived data of the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) onboard the Advanced Land Observing Satellite (ALOS, nicknamed “Daichi”), which was operated from 2006 to 2011. The overview and the processing status of the global...
Panchromatic Remote-sensing Instrument for Stereo Mapping, one of onboard sensors carried by Advanced Land Observing Satellite, was designed to generate worldwide topographic data with its optical stereoscopic observation. The sensor had observed huge amount of stereo images all over the world during the mission life of the satellite from 2006 through 2011. To utilize all these archive data we proceed...
Panchromatic Remote-sensing Instrument for Stereo Mapping, one of onboard sensors carried by Advanced Land Observing Satellite, was designed to generate worldwide topographic data with its stereoscopic, high resolution observation. The global digital surface models are expected to be generated by utilizing the archives of the stereo images observed during more than five years of the satellite mission...
The special and temporal analysis is a primitive approach in the remote sensing field. The Advanced Land Observing Satellite (ALOS, nicknamed ‘Daichi’) has been operated very well from 2006 to 2011, and mainly observed global land region with fine resolutions by three sensors i.e. an L-band Synthetic Aperture Radar called PALSAR and two optical instruments called PRISM and AVNIR-2. They have been...
The Advanced Land Observing Satellite (ALOS, nicknamed ‘Daichi’) was launched on January 2006, and has operated very well. However, its operation moved to the low load mode (LLM) since April 22, 2011, and was subsequently followed by an official termination on May 12, 2011. Notwithstanding, approx. 6,500,000 scenes of archived data covering the entire globe are available to users. Therefore the calibration...
Panchromatic Remote-sensing Instrument for Stereo Mapping, one of onboard sensors carried by Advanced Land Observing Satellite, was designed to generate worldwide topographic data with its high resolution and stereoscopic observation. More than six thousand scenes of digital surface model were processed so far from its images in Japan Aerospace Exploration Agency. The areas of processed scenes cover...
The Rational Polynomial Coefficients (RPC) is being widely used for representing the physical sensor models of satellite optical images. The Remote Sensing Technology Center of Japan (RESTEC) has already released the RPC data sets for Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) and Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) onboard Advanced Land Observing...
Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) carried by Advanced Land Observing Satellite (ALOS) was designed to generate worldwide topographic data with its high resolution and stereoscopic observation. According to this aim, we developed the software of generating Digital Surface Model (DSM) data. Following the accumulations of PRISM stereoscopic observation data during over...
