Validating the accuracy of land cover products using a reliable reference dataset is an important task. A reliable reference dataset is produced with information derived from ground truth data. Recent...
Within the surrounding frameworks of the programme Global Monitoring for Environment and Security (GMES) (EEA, 2006) and the Directive for the Infrastructure for Spatial Information in the European ...
The National Geographic Institute of Spain (IGN) is the National Reference Centre in Land Cover and Use (EIONET′s National Reference Centre for Soil, by mandate of the National Focal Point, the Spanis...
Land cover mapping in most cases results in thematic maps which are in general not a perfect representation of the reality. They always contain errors due to the method used for its production or simp...
The need for Digital Elevation Model (DEM) checking has raised since the automated matching techniques emerged. The use of reference data is a luxury and therefore cannot be used in all cases. This ar...
Juvenile cynomolgus monkeys are valuable models for studying human diseases. Reference data of clinical chemistry, haematology and blood coagulation parameters of juvenile cynomolgus monkeys are very ...
Purpose: The mean expected values of pedometer-determined steps per day for children and adolescents have been derived primarily from isolated studies on small or specific populations. The purpose of ...
提出了一种散乱点云局部型面参考数据的快速查询算法。该算法改进R*-tree建立散乱点云的空间索引结构,获取采样点所在叶结点,依据该结点MBR构造空心球,深度优先遍历R*-tree获取空心球内数据点,通过动态扩展空心球内外半径实现散乱点云局部型面参考数据的快速获取。实验表明,该算法可适用于各种复杂型面散乱点云,提高了查询的准确性与查询效率。
Background: Several methods have been used to estimate adiposity with high precision, but BMI has become the most common marker in identifying overweight and obese subjects. This study was performed t...
Background: Body mass index (BMI) reference data for school children in ages between 6.5 to 11.5 years in Shiraz (South of Iran) are presented. Materials and method: The data are based on a random mu...
