The lacking of 1:50000 topographic maps in western China is inconvenient to the national economic development. The rapid development of space technology, computer technology and information technology provides technological support for the remote sensing application. In addition, the enhancement of ability of obtaining hyper-resolution data provides data for feature extraction of ground objects...

The purpose of this project is to test High Resolution Stereoscopic (HRS) data of SPOT5. This project is done in the framework of the “HRS study Team” international test, supported by ISPRS-CNES. The Digital Elevation Model (DEM) was derived from the HRS data and was evaluated by using a 3D reference data set. The study site for HRS data is located in Manosque, France. It is a countryside lands...

Although they correspond to an important fraction of the total area of mountain glaciers (33000 km out of 546000 km), Himalayan glaciers and their mass balance are poorly sampled. For example, between 1977 and 1999, the average area surveyed each year on the field was 6.8 km only. No direct mass balance measurement is available after 1999. To contribute to fill this gap, we use remote sensing d...

Russian Doll Search (RDS) is a well-known algorithm for combinatorial optimization. In this paper we extend it from mono-objective to multi-objective optimization. We demonstrate its practical applicability in the challenging multipleorbit SPOT5 instances. Besides being much more efficient than any other alternatives, multi-objective RDS can solve an instance which could not have been solved pr...

Two visibility tests have been made on a fusion of panchromatic and multi-spectral SPOT5 images. The tests differ in the type of regions (sub-urban versus rural) and in the panchromatic image resolution (5m versus 3m). Two independent photo-interpretors had to extract the road network and the built-up area on part of a georeferenced image. The resulting shapes were compared with the actual data...

In this paper we propose a new criterion, based on Minimum Description Length (MDL), to estimate an optimal number of clusters. This criterion, called Kernel MDL (KMDL), is particularly adapted to the use of kernel K-means clustering algorithm. Its formulation is based on the definition of MDL derived for Gaussian Mixture Model (GMM). We demonstrate the efficiency of our approach on both synthe...

We compare two independent estimates of the rate of elevation change and geodetic mass balance of the Northern Patagonian Icefield (NPI) between 2000 (3,856 km2) and 2012 (3,740 km2) from space-borne data. The first is obtained by differencing the Shuttle Radar TopographyMission (SRTM) digital elevationmodel (DEM) from February 2000 and a Satellite pour l’Observation de la Terre 5 (SPOT5) DEM f...
