Abstract
A new global land cover database for the year 2000 (GLC2000) has been produced by an international partnership of 30 research groups coordinated by the European Commission's Joint Research Centre. The database contains two levels of land cover information—detailed, regionally optimized land cover legends for each continent and a less thematically detailed global legend that harmonizes regional legends into one consistent product. The land cover maps are all based on daily data from the VEGETATION sensor on‐board SPOT 4, though mapping of some regions involved use of data from other Earth observing sensors to resolve specific issues. Detailed legend definition, image classification and map quality assurance were carried out region by region. The global product was made through aggregation of these. The database is designed to serve users from science programmes, policy makers, environmental convention secretariats, non‐governmental organizations and development‐aid projects. The regional and global data ar...

MODIS Collection 5 global land cover: Algorithm refinements and characterization of new datasets

TL;DR: The datasets and algorithms used to create the Collection 5 MODIS Global Land Cover Type product, which is substantially changed relative to Collection 4, are described, with a four-fold increase in spatial resolution and changes in the input data and classification algorithm.

Farming the planet: 1. Geographic distribution of global agricultural lands in the year 2000

TL;DR: In the year 2000, the United Nations reported that 28.6 million km 2 of cropland (12% of the Earth's ice-free land surface) and 28.0 (90% confidence range of 23.6-30.0) million km2 of pasture (22%) were converted to pasture as mentioned in this paper.

Putting people in the map: anthropogenic biomes of the world

TL;DR: In this paper, the authors presented the first characterization of terrestrial biomes based on global patterns of sustained, direct human interaction with ecosystems and identified the anthropogenic biomes through empirical analysis of global population, land use, and land cover.

Global land cover mapping at 30 m resolution: A POK-based operational approach

TL;DR: In this article, an approach based on the integration of pixel-and object-based methods with knowledge (POK-based) has been developed to handle the classification process of 10 land cover types, i.e., firstly each class identified in a prioritized sequence and then results are merged together.

Global land cover mapping from MODIS: algorithms and early results

TL;DR: This product provides maps of global land cover at 1-km spatial resolution using several classification systems, principally that of the IGBP, and a supervised classification methodology is used that exploits a global database of training sites interpreted from high-resolution imagery in association with ancillary data.

Global land cover classification at 1 km spatial resolution using a classification tree approach

TL;DR: In this paper, a 1km spatial resolution land cover classification using data for 1992-1993 from the Advanced Very High Resolution Radiometer (AVHRR) is presented. But the approach taken involved a hierarchy of pair-wise class trees where a logic based on vegetation form was applied until all classes were depicted.

Modeling the Exchanges of Energy, Water, and Carbon Between Continents and the Atmosphere

TL;DR: Modern schemes incorporate biogeochemical and ecological knowledge and, when coupled with advanced climate and ocean models, will be capable of modeling the biological and physical responses of the Earth system to global change, for example, increasing atmospheric carbon dioxide.

Amazon Deforestation and Climate Change

TL;DR: A coupled numerical model of the global atmosphere and biosphere has been used to assess the effects of Amazon deforestation on the regional and global climate; there was a significant increase in surface temperature and a decrease in evapotranspiration and precipitation over Amazonia.

SMAC: a simplified method for the atmospheric correction of satellite measurements in the solar spectrum

TL;DR: In this article, the authors describe a computationally fast and accurate technique for the atmospheric correction of satellite measurements in the solar spectrum, which is based on a set of equations with coefficients which depend on the spectral band of the sensor.
