Uncertainty Assessment in Dasymmetric Mapping
نویسنده
چکیده
Dasymmetric mapping is an areal interpolation method which transfer data from the source zones to the target zones. Although many dasymmetric mapping methods have been developed, few research have been conducted from accuracy assessment perspective. This paper reviews the methods which can be used to serve this purpose. Three methods were experimented: (1) cartographic mapping, (2) summary statistics, and (3) sequential simulation. A dasymetric mapping method based on geostatistics is used to illustrate the methods. In assessing the uncertainty and accuracy of a dasymetric mapping method, it is suggested that all three methods should be considered in order to achieve a comprehensive description.

متن کاملAccuracy Assessment of GLM and FDA Models for Land Subsidence Susceptibility Mapping in Semnan Plain
The mechanism of land subsidence and soil deformation is the dissipation of the excess pore water pressure and the compaction of the soil skeleton under the effect of natural or man-made factors. Land subsidence has occurred in more of 300 plains of Iran, and Semnan Plain is one of the most important areas that face to this phenomenon. The aim of current research was land subsidence susceptibil...
متن کاملAssessment of Neonate's Congenital Hypothyroidism Pattern Using Poisson Spatio-temporal Model in Disease Mapping under the Bayesian Paradigm during 2011-18 in Guilan, Iran
Background: Congenital Hypothyroidism (CH) is one of the reasons for mental retardation and defective growth in neonates. It can be treated if it is diagnosed early. The congenital hypothyroidism can be diagnosed using newborn screening in the first days after birth. Disease mapping helps to identify high-risk areas of the disease. This study aimed to evaluate the pattern of CH using the Poisso...

This research investigated desertification and mapping ofdesertification in Abuzaydabad, near Kashan, Iran, with an emphasis on land criteria using an IMDPA model.Different studies have assessed land degradation or desertificat...
متن کاملAssessment of Green Supplier Development Programs by a New Group Decision-Making Model Considering Possibilistic Statistical Uncertainty
The assessment and selection of green supplier development programs are an intriguing and functional research subject. This paper proposes a group decision-making approach considering possibilistic statistical concepts under uncertainty to assess green supplier development programs (GSDPs) via interval-valued fuzzy sets (IVFSs). Possibility theory is employed to regard uncertainty by IVFSs. A n...
