“…ALOS PRISM acquires data in triple mode to generate an accurate Digital Surface Model and < 10 m geometric accuracy is achievable (Tadono et al 2009). According to the Remote Sensing Technology Centre of Japan (RESTEC), RMSE of ALOS PRISM RPC ranges ~0.5-10 m; however, in most cases, the errors are in the range 1-5 m (http://www.alos-restec.jp/products_e.html).…”

This study used Corona KH-4A and Advanced Land Observing Satellite (ALOS) PRISM images to generate digital terrain models (DTMs) of the distal part of Imja Glacier, where a few supra-glacial ponds (~0.07 km 2 ) expanded into the large Imja Glacier Lake (Imja Tsho, ~0.91 km 2 ) between 1964 and 2006. DTMs and subsequently derived topographical maps with contour intervals of 1 m were created from the high-resolution images (Corona in 1964 and ALOS in 2006) in the Leica Photogrammetric Suite (LPS) platform. The DTMs and topographic maps provided excellent representation of the elevation and micro-topography of the glacier surface, such as its supra-glacial ponds/lake, surface depressions, and moraine ridges, with an error of about +/-4 m (maximum). The DTMs produced from the Corona and ALOS PRISM images are suitable for use in studies of the surface change of glaciers. The topographical maps produced from the Corona data (1964) showed that part of the dead ice in the down-glacier area was even higher than the top of the lateral moraine ridges, while the glacier surface in the upglacier area was noticeably lower than the moraine crests. This suggests more extensive melting of glacier ice in the up-glacier area before 1964. The average lowering of the glacier surface from 1964 to 2006 was 16.9 m for the dead-ice area west of the lake and 47.4 m for the glacier surface east of the lake; between 1964 and 2002, the lake surface lowered by 82.3 m. These figures represent average lowering rates of 0.4, 1.1, and 2.2 m/year for the respective areas.

“…Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) was an optical sensor onboard the Advanced Land Observing Satellite (ALOS) operated from 2006 to 2011, and was designed to generate worldwide elevation data. The sensor consists of three independent panchromatic radiometers for viewing forward, nadir, and backward in 2.5 m ground resolution producing a triplet stereoscopic image along its track (Tadono et al 2009). Though the satellite already ended its mission life it left us huge amount of stereo images all over the world (Takaku et al 2013).…”

ABSTRACT:Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM), one of onboard sensors carried on the Advanced Land Observing Satellite (ALOS), was designed to generate worldwide topographic data with its optical stereoscopic observation. The sensor consists of three independent panchromatic radiometers for viewing forward, nadir, and backward in 2.5m ground resolution producing a triplet stereoscopic image along its track. The sensor had observed huge amount of stereo images all over the world during the mission life of the satellite from 2006 through 2011. We have semi-automatically processed Digital Surface Model (DSM) data with the image archives in some limited areas. The height accuracy of the dataset was estimated at less than 5m (rms) from the evaluation with ground control points (GCPs) or reference DSMs derived from the Light Detection and Ranging (LiDAR). Then, we decided to process the global DSM datasets from all available archives of PRISM stereo images by the end of March 2016. This paper briefly reports on the latest processing algorithms for the global DSM datasets as well as their preliminary results on some test sites. The accuracies and error characteristics of datasets are analyzed and discussed on various fields by the comparison with existing global datasets such as Ice, Cloud, and land Elevation Satellite (ICESat) data and Shuttle Radar Topography Mission (SRTM) data, as well as the GCPs and the reference airborne LiDAR/DSM.

Geometric Potential Assessment for ZY3-02 Triple Linear Array Imagery

et al. 2017

ZiYuan3-02 (ZY3-02) is the first remote sensing satellite for the development of China's civil space infrastructure (CCSI) and the second satellite in the ZiYuan3 series; it was launched successfully on 30 May 2016, aboard the CZ-4B rocket at the Taiyuan Satellite Launch Center (TSLC) in China. Core payloads of ZY3-02 include a triple linear array camera (TLC) and a multi-spectral camera, and this equipment will be used to acquire space geographic information with high-resolution and stereoscopic observations. Geometric quality is a key factor that affects the performance and potential of satellite imagery. For the purpose of evaluating comprehensively the geometric potential of ZY3-02, this paper introduces the method used for geometric calibration of the TLC onboard the satellite and a model for sensor corrected (SC) products that serve as basic products delivered to users. Evaluation work was conducted by making a full assessment of the geometric performance. Furthermore, images of six regions and corresponding reference data were collected to implement the geometric calibration technique and evaluate the resulting geometric accuracy. Experimental results showed that the direct location performance and internal accuracy of SC products increased remarkably after calibration, and the planimetric and vertical accuracies with relatively few ground control points (GCPs) were demonstrated to be better than 2.5 m and 2 m, respectively. Additionally, the derived digital surface model (DSM) accuracy was better than 3 m (RMSE) for flat terrain and 5 m (RMSE) for mountainous terrain. However, given that several variations such as changes in the thermal environment can alter the camera's installation angle, geometric performance will vary with the geographical location and imaging time changes. Generally, ZY3-02 can be used for 1:50,000 stereo mapping and can produce (and update) larger-scale basic geographic information products.
