[Termes IGN] télémétrie laser terrestreRésumé : (Auteur) A large-scale survey of a high-voltage substation in the Tver region of Russia, was to be produced at a scale of 1:500, to include high accuracy determination of power line portals and associated features. Using the results of a laser scanning survey, a detailed 3D model of each portal and bearing was also generated. Together with reflectionless tachymeters, utilizing laser scanning technology can greatly improve the performance of a field survey, particularly in such a difficult object-oriented location as the high-voltage substation.

[Termes IGN] Triangulated Irregular NetworkRésumé : (Auteur) Exploration and preservation of Por-Bajin fortress, testimony to the former presence of ancient civilisation in the wildness of Siberia, is one of the largest-scale projects in modern archeology. Combining terrestrial laser-scanning, magnetic field and electrical resistance data revealed anomalies that had remained concealed during fieldwork and in aerial photos.

[Termes IGN] urbanisationRésumé : (Auteur) The twentieth century saw fundamental shifts in northern Eurasian political and land-management paradigms, in Russia culminating in the political transition of 1991. We used the 1972 to 2001 Landsat archive bracketing this transition to observe change trends in southern central Siberian Russia in primarily forested study sites. Landsat resolved conifer, mixed, deciduous and young forest; cuts, burns, and insect disturbance; and wetland, agriculture, bare, urban, and water land covers. Over 70 percent of forest area in the three study sites was likely disturbed prior to 1974. Conifer forest decreased over the 1974 to 2001 study period, with the greatest decrease 1974 to 1990. Logging activity (primarily in conifers) declined more during the 1991 to 2001 post-Soviet period. The area of Young forest increased more during the 1974 to 1990 time period. Deciduous forest increased over both time periods. Agriculture declined over both time periods contributing to forest regrowth in this region.

[Termes IGN] variation saisonnièreRésumé : (Auteur) Reliable monitoring of seasonality in the forest canopy leaf area index (LAI) in Siberian forests is required to advance the understanding of climate–forest interactions under global environmental change and to develop a forest phenology model within ecosystem modeling. Here, we compare multi-satellite (AVHRR, MODIS, and SPOT/VEGETATION) reflectance, normalized difference vegetation index (NDVI), enhanced vegetation index (EVI), and LAI with aircraft-based spectral reflectance data and field-measured forest data acquired from April to June in 2000 in a larch forest near Yakutsk, Russia. Field data in a 30 x 30-m study site and aircraft data observed around the field site were used. Larch is a dominant forest type in eastern Siberia, but comparison studies that consider multi-satellite data, aircraft-based reflectance, and field-based measurement data are rarely conducted. Three-dimensional canopy radiative transfer calculations, which are based on Antyufeev and Marshak's [Antyufeev, V.S., & Marshak, A.L. (1990). Monte Carlo method and transport equation in plant canopies, Remote Sensing of Environment, 31, 183–191] Monte Carlo photon transport method combined with North's [North, P.R. (1996). Three-dimensional forest light interaction model using a Monte Carlo method, IEEE Transactions on Geoscience and Remote Sensing, 34(4), 946–956] geometric-optical hybrid forest canopy scene, helped elucidate the relationship between canopy reflectance and forest structural parameters, including several forest floor conditions. Aircraft-based spectral measurements and the spectral response functions of all satellite sensors confirmed that biases in reflectance seasonality caused by differences in spectral response functions among sensors were small. However, some reflectance biases occur among the near infrared (NIR) reflectance data from satellite products; these biases were potentially caused by absolute calibration errors or cloud/cloud shadow contamination. In addition, reflectance seasonality in AVHRR-based NIR data was very small compared to other datasets, which was partially due to the spring-to-summer increase in the amount of atmospheric water vapor. Radiative transfer simulations suggest that bidirectional reflectance effects were small for the study site and observation period; however, changes in tree density and forest floor conditions affect the absolute value of NIR reflectance, even if the canopy leaf area condition does not change. Reliable monitoring of canopy LAI is achieved by minimizing these effects through the use of NIR reflectance difference, i.e., the difference in reflectance on the observation day from the reflectance on a snow-free/pre-foliation day. This may yield useful and robust parameters for multi-satellite monitoring of the larch canopy LAI with less error from intersensor biases and forest structure/floor differences. Further validation with field data and combined use of other index (e.g. normalized difference water index, NDWI) data will enable an extension of these findings to all Siberian deciduous forests.

[Termes IGN] télémétrie laser terrestreRésumé : (Auteur) The 6th International Conference on Laser Scanning & Digital Aerial Photography, organised jointly by the Russian Society of Photogrammetry & Remote Sensing (RSPRS) and the giant Gazprom company, was held in Moscow between 6th and 8th december 2006. As the conference title suggested, it was focused on three main Themes -(i) airborne laser scanning; (ii) terrestrial (ground-based) laser scanning; and (iii) airborne digital photography, with particular reference to their applications within Russia. On the one hand, the detailed papers on these three technologies were given mainly by Western system suppliers or their Russian representatives. On the over hand, the papers on the applications of these technologies were presented mainly by Russian contributors, who have adopted these technologies enthusiastically with numerous interesting and varied applications.
