The idea of development of an Integrated Land Information System (ILIS) for the region as an initial stepof future advanced integrated observing systems is considered as a promising way. The ILIS could serve (1) forintroduction of a unified system of classification and quantification of environment, ecosystems and landscapes;(2) as a benchmark for tracing the dynamics of land use – land cover and ecosystems parameters, particularly forforests; (3) as a systems background for empirical assessment of indicators of an interest (e.g., components ofbiogeochemical cycles); (4) comparisons, harmonizing and mutual constraints of the results obtained by differentmethods; (5) for parameterization of surface fluxes for the ‘atmosphere-land’ system; (6) for use in divers modelsand for models’ validation; (7) for downscaling of available information to a required scale; (8) for understandingof gradients for up-scaling of “point” data, etc.The ILIS is presented in form of multi-layer and multi-scale GIS that includes a hybrid land cover (HLC) by adefinite date and corresponding legends and attributive databases. The HLC is based on relevant combination of a“multi” remote sensing concept that includes sensors of different type and resolution and ground data. The ILIS in-cludes inter alia (1) general geographical and biophysical description of the territory (landscapes, soil, vegetation,hydrology, bioclimatic zones, permafrost etc.); (2) diverse datasets of measurements in situ; (3) sets of empiricaland semi-empirical aggregation and auxiliary models, (4) data on different inventories and surveys (forest inven-tory, land account, results of forest monitoring); (5) spatial and temporal description of anthropogenic and naturaldisturbances; (5) climatic data with relevant temporal resolution etc. The ILIS should include only the data withknown uncertainties and in details, which would allow assessing most important characteristics of environmentand the biosphere (e.g., Net Ecosystem Carbon Budget) within preliminary specified level of uncertainty. Thebasic spatial resolution is 1km with possibilities to use finer resolution for regions of rapid changes or intensiveecological, atmospheric, hydrological etc. processes.Experiences of development of a prototype of the ILIS for Russia illustrated advantages of such an approach: asubstantial gain in resources and time under organization of multidisciplinary integrated studies; availability ofa solid background for development of clusters of integrated models that include meteorological, environmental,climatic, ecological, economic, social and other dimensions; open access to accumulated data, information andknowledge etc. Yet, there are significant difficulties in ILIS developments: a need of a system which would beopen for changes and improvements; availability of long-period mechanisms for maintaining the system; possiblecontradictions with national information policies etc.
