A Bayesian Based Method to Generate a Synergetic Land-Cover Map from Existing Land-Cover Products
Global land cover is an important parameter of the land surface and has been derived by various researchers based on remote sensing images. Each land cover product has its own disadvantages and limitations. Data fusion technology is becoming a notable method to fully integrate existing land cover information. In this paper, we developed a method to generate a synergetic global land cover map (s...
متن کاملA methodology to generate a synergetic land-cover map by fusion of different land-cover products
The main goal of this study is to develop a general framework for building a hybrid land-cover map by the synergistic combination of a number of land-cover classifications with different legends and spatial resolutions. The proposed approach assesses class-specific accuracies of datasets and establishes affinity between thematic legends using a common land-cover language such as the UN Land-Cov...
متن کاملCreation of New Global Land Cover Map with Map Integration
We present here a new approach to the development of a global land cover map. We combined three existing global land cover maps (MOD12, GLC2000, and UMD) based on the principle that the majority view prevails and validated the resulting map by using information collected as part of the Degree Confluence Project (DCP). We used field survey information gathered by DCP volunteers from 4211 worldwi...
متن کاملLaco-wiki: an Open Access Online Portal for Land Cover Validation
The LACO-Wiki tool represents an open access, online portal that offers standardized land cover validation at local to global scales. LACO-Wiki integrates the LACOVAL prototype for land cover validation and the Geo-Wiki system for visualization, validation and crowdsourcing of land cover. This paper presents a conceptual overview of the LACO-Wiki system and describes the main validation workflo...
متن کاملCreating Spatial Information: Commissioning the UK Land Cover Map 2000
Environmental datasets are subject to ontological differences in the way that information is recorded and reported. One of the implications is that environmental monitoring and the identification of loci of change is difficult. This generic problem is explored with reference to land cover mapping in the UK. The decennial land cover projects (LCMGB and LCM2000) are introduced and their differenc...
