|Abstract:||Accurate and reliable information about land areas and area changes is critically important for developing inventories that are consistent with good practice as defined in the IPCC Guidelines. In this context, remote sensing imagery assumes a great importance as it may represent a cost-effective tool for inventory compilers, especially with the medium resolution (c. 30 m) global coverage of satellite imagery obtained from satellites such as Landsat. Information on availability and capabilities of satellite remote sensing data could be extremely useful in filling the gaps in the availability of data regarding forests and other land cover. This background paper is intended to present how the remote sensing imagery could be useful to the inventory compilers for the Land Use, Land Use Change and Forestry (LULUCF) sector for different level of data needs. Starting from a brief analysis of the current use of remote sensing (RS) in GHG inventories, the paper analyses the current operational capabilities of satellite remote sensing, including the discussion of the related uncertainties. In this analysis, we focused on remote sensing data from satellite and thus do not consider remote sensing data from airborne such as aerial photography. The two reasons for this restriction are: (i) there is already a long experience on the use of airborne data by national land use planning agencies and (ii) airborne data are more similar to field data in relation to their availability (limited to specific countries or regions) and to cost/accuracy issues (airborne data are usually much more expensive but can provide more spatially detailed information than satellite data). Finally, this paper discusses specific issues on which additional guidance could be useful and presents the potential role of the ¿Global Observation of Forest and Land Cover Dynamics¿ (GOFC-GOLD) - a technical panel of ¿Global Terrestrial Observing System¿ (GTOS). Specifically, GOFC-GOLD could stimulate a consensus perspective among the global community of earth observation experts on methodological issues related to the use of RS for national-level land cover and land use monitoring, and the related accuracy assessment procedures. During the preparation of this background paper, the expertise from members of the GOFC-GOLD Land Cover Team was complemented by experts in UNFCCC reporting.|
