Spatial Join on Positional Uncertain Data
نویسندگان
چکیده
This paper presents a probabilistic spatial join on positional uncertain data designed to be a) generalist; b) accurate and c) efficient. A proposed progressive Monte Carlo algorithm is used in the refinement step and the Chebyshev inequality is applied in the filtering one in order to provide efficiency, efficacy and generality. The experiments show that the current propose is Pareto efficient concerning these requirements, i.e., it is not outperformed by any competing method. Also, the solution’s parameters relating accuracy and efficiency may be adjusted to maximize the gain in one while relaxing the other according to user’s demand.

Probabilistic Spatial Database Operations
Spatial databases typically assume that the positional attributes of spatial objects are precisely known. In practice, however, they are known only approximately, with the error depending on the nature of the measurement and the source of data. In this paper, we address the problem how to perform spatial database operations in the presence of uncertainty. We first discuss a probabilistic spatia...
متن کاملInterval Count Semi-Joins
Interval joins find applications in several domains, including temporal and spatial databases, uncertain data management, streaming data processing. In this paper, we study the evaluation of an interval count semi-join (ICS J ) operation that can be used for selecting or ranking intervals based on the number of join pairs they appear in. We extend the state-of-the-art algorithm for interval joi...
متن کاملA Survey of Join Methods for Uncertain Data
The join query is a very important database primitive. It combines two datasets R and S (R = S in case of a self-join) based on some query predicate into one set such that the new set contains pairs of objects of the two original sets. In various application areas, e.g. sensor databases, location-based services or face recognition systems, joins have to be computed based on vague and uncertain ...
متن کاملDistances for Uncertain Topological Relations
Considering uncertainty of spatial data in any GIS analysis is a theme of actual research but far from practicability One prerequisite is the availability of descriptions concerning uncertainty meta data and another is the attachment of uncertainty to spatial analysis In our contribution we propose a method to determine the topological relation between two positional uncertain regions The decis...
متن کاملMandatory Critical Points of 2D Uncertain Scalar Fields
This paper introduces a novel, non-local characterization of critical points and their global relation in 2D uncertain scalar fields. The characterization is based on the analysis of the support of the probability density functions (PDF) of the input data. Given two scalar fields representing reliable estimations of the bounds of this support, our strategy identifies mandatory critical points: ...
