The estimation of accuracy of thematic maps derived from remotely sensed data used in conjunction with a geographic information system is presented. A systematic random sampling techique is proposed t...
Spatial sampling optimization is an important issue for both geo-chemists and geo-statisticians. Many spatial sampling optimization methods have been previously developed. In this paper, we present a ...
Sampling methods have to be applied in agricultural condition monitoring at national scale. When selecting sampling methods, more attention needs to be paid not only to objects monitored, but also to ...
The experiments were conducted for monitoring crop area by spatial sampling methods in a winter wheat main production region with a size of 42Km×42Km in Hengshui City, Hebei Province in China to optim...
The sampling inspection model proposed by this paper is the key for the quality inspection and assessment of geological data, which is based on the present standards, research findings, and the qualit...
A simple simulator was developed to test whether airborne laser scanning can be used as a strip sampling tool for forest inventory purposes. The simulator is based on the existing two stages,grid base...
Airborne laser scanning (lidar) can be a valuable tool in double-sampling forest survey designs. Lidar-derived forest structure metrics are often highly correlated with important forest inventory vari...
In this paper, an effective spatial sampling method is preliminary explored to assess the quality of the topographic data. The most novel idea in this study is we think the error as noise in the signa...
In this paper, we analyses problems that remote sensing technique met in China. And provide a new methodology on stratified sampling technique. During the stratification procedure, physical factors,...
Accuracy assessment is an important step in the process of analyzing remote sensing data. It determines the value of the resulting data to a particular user, i.e. the information value. Remote sensin...
The present investigation describes a method for sampling bidirectional reflectance information from multiangular airborne images.The method uses high resolution surface models in the determination of...
A web-based validation is necessary for assessing the accuracy of Globalland30. As one of the obstacles in validation of global land cover data, it is a challenge to effectively select a reasonable sa...
How to effectively describe ecological patterns in nature over broader spatial scales and build a modeling ecological framework has become an important issue in ecological research. We test four model...
In this paper, the MODIS remote sensing data, featured with low-cost, high-timely and moderate/low spatial resolutions, in the North China Plain (NCP) as a study region were firstly used to carry out ...
The paper presents a recent 3D scanning project performed with long range scanning technology showing how a complex sampled dataset can be processed with the features available in MeshLab, an open sou...
