Commission VI, WG VI/4 KEY WORDS: Larsen B, DISP, DEM, Reconstruction ABSTRACT:Antarctica is an important part of the earth system and crucial to global sea-level and climate change. In 1995, a number of US intelligence satellite photographs from the1960s to 1970s have been declassified, only a portion of which (ARGON) covers the Antarctica. It provides a broader perspective to study the early Antarctica and it's very important for us to study the changes in the early stage of Antarctica. In this paper, a hierarchical stereo image matching strategy was used to reconstruct a digital elevation model of the Larsen B region of Antarctica Peninsula in 1960s using ARGON images. The accuracy of the matching result estimated in all layers is within one scanned-pixel of 33m and the accuracy of geometric modelling after bundle adjustment estimated by using check points is within one nominal pixel of 140m. In the future, the elevation changes from 1960s of Larsen B tributary glaciers will be analysed.

“…First analogue satellite imagery were collected in the '60s, when a few data sets of images for intelligence surveillance were captured and, after decades, declassified and made available to the public (Kim et al, 2007;Li et al, 2017). At the beginning of the '70s the era of spaceborne imaging sensors started and has impressively developed up until today.…”

Commission V, WG V/7KEY WORDS: Aerial photogrammetry, Analogue, Archive photos, Civil engineering, Low-cost, Project planning ABSTRACT:Archive aerial photos represent a valuable heritage to provide information about land content and topography in the past years. Today, the availability of low-cost and open-source solutions for photogrammetric processing of close-range and drone images offers the chance to provide outputs such as DEM's and orthoimages in easy way. This paper is aimed at demonstrating somehow and to which level of accuracy digitized archive aerial photos may be used within a such kind of low-cost software (Agisoft Photoscan Professional ® ) to generate photogrammetric outputs. Different steps of the photogrammetric processing workflow are presented and discussed. The main conclusion is that this procedure may come to provide some final products, which however do not feature the high accuracy and resolution that may be obtained using high-end photogrammetric software packages specifically designed for aerial survey projects. In the last part a case study is presented about the use of four-epoch archive of aerial images to analyze the area where a tunnel has to be excavated.

“…Kim et al used the method of spatial resection to geolocate the ARGON image of Queen Maud Land precisely, then discussed the difference in this ice shelf between the 1963 ARGON image the 1997 RADARSAT-1 image (Kim et al, 2001). Kim and Jezek et al used the ARGON images covering 62 scenes of the Antarctica to produce a mosaic of the entire Antarctic and extracted the coastline (Kim et al, 2007). Wang et al used the control points acquired by WorldView images to geolocate the Argon images at the Larsen ice shelf in the Antarctic Peninsula and measured the ice flow velocity for 1960s to 1970s (Wang et al, 2016).…”

ABSTRACT:Ice flow velocity is a vital parameter for estimating the ice mass balance of glaciers in Antarctica. Especially long time serial observation of the surface velocity is of great significance to assessing the relationship between Antarctic ice materials and global climate change. However, the existing research on Antarctic ice velocity based on remote sensing data since 1970s due to the harsh climate in Antarctica. This paper presents an ice flow velocity estimating method includes image pre-processing, geometric model reconstruction, image ortho-rectification and feature matching by using ARGON images token in 1963 and Landsat images collected form 1973 to 1989.Considering the temporal-spatial distributions of ARGON images and Landsat images in Antarctica, two different methods respectively based on ortho-photos pair and Non-Ortho photos are adopted in this paper. More specifically, when there exist two stereo pairs taken in different time in the glacier region, after being ortho-rectified, the stereo pairs can be used to calculate ice flow velocity based on feature matching method. Otherwise, a parallax decomposition method that separates the effect of the terrain relief from the ice flow motion is applied when there only exists one stereo pair with a certain time interval. With this method, glacier surface velocity is available in the glacier region lacked enough stereo pairs. The methods mentioned above for estimating ice flow velocity are applied in Totten, Amery and Fimbul, etc. in eastern Antarctica. Furthermore, a 1960-80s ice flow speed map in the main glaciers of East Antarctica is produced for the first time.
