Fusing Multiple Land Cover Products Based on Locally Estimated Map-Reference Cover Type Transition Probabilities

چکیده
There are a variety of land cover products generated from remote-sensing images. However, misclassification errors in individual and inconsistency among them undermine their utilities for research other applications. While it is worth developing advanced pattern classifiers utilizing the images finer spatial, temporal, and/or spectral resolution increased classification accuracy, also sensible to increase map accuracy through effective fusion by exploiting complementarity multi-source over study area. This paper presents novel method that works weighting multiple source based on map-reference type transition probabilities, which predicted using random forest pixels. The proposed was tested compared with three alternatives: consensus-based weighting, forest, locally modified Dempster–Shafer evidential reasoning, case study, Shaanxi province, China. For this types (GlobeLand30, FROM-GLC, GLC_FCS30) two nominal years (2010 2020) were used as base maps fusion. Reference sample data model training testing collected following robust stratified sampling design allows augmenting reference flexibly. Accuracy assessments show overall accuracies (OAs) fused have been improved (1~9% OAs), outperforming methods 2~8% OAs. does not need products’ systems harmonized beforehand, thus being highly recommendable fusing products.

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 کاملLand Cover Classification Based on General Type-2 Fuzzy Classifiers
This paper proposes a fuzzy classifier based on type-2 fuzzy sets to be applied in land cover classification. The classifier is built on the basis of the available data and considers the merging of information drawn from different experts. The data regard a thematic mapper representing the land cover of a real plain cultivated area. The experts are represented by different bands which classify ...
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...

This paper describes first results of a land cover / land use (LCLU) classification of Germany, developed at the German Remote Sensing Data Center (DLR-DFD). The automated, yearly updated product is based on MERIS level 2 full resolution data. The classification procedure consists of two main steps, namely a multispectral and a multitemporal analysis. The legend of the LCLU map is defined accor...
