Propagation of spatial imprecision in imprecise quantitative data in agronomy
نویسندگان
چکیده
One of the stakes of Observox, an observatory of agricultural practices, is to deal with imperfect spatial information and to always associate a quality evaluation to acquired or computed data. So, we introduce the notion of fuzzy geographical entities. Then, we consider both spatial and quantitative information in order to obtain fuzzy local quantitative information. This paper proposes a new operator which gives the fuzzy quantity of spatially disseminated chemical products for each location.

Accessing Imprecise Data: An Approach Based on Intervals
In many real world applications (even in banking), imprecise data is a matter of fact. However, classic database management systems provide little if any help in the management of imprecise data. We are applying methods from interval arithmetic, epsilon serializability, and other related areas to help the application designers in the management of naturally imprecise data. Our approach includes...

متن کاملStudy of Spatial Fusion of Geographical Entities and Quantitative Information in Accordance with their Imprecision Application to agricultural information in Observox
The article deals with imprecise geographical entities modelled according to the fuzzy set theory for both spatial and quantitative information. It presents the issues of fusion of fuzzy geographical objects according to its storing modes (raster, vector) in a mutualised geographical information system (GIS). We study the aggregation of imprecise spatial entities and its impact in the imprecise...

This report summarizes preliminary work on a framework for imprecise reasoning about spatial information, in particular spatial information in geographic information systems. It is based on papers previously published by Jonathan Histed, Ute L orch, David Poon, and the author. Geographic information systems have gained an increasing interest over the recent years. However, their abilities are ...
متن کاملPropagating Imprecise Probabilities in Bayesian Networks
Often experts are incapable of providingèxact' probabilities; likewise, samples on which the probabilities in networks are based must often be small and preliminary. In such cases the probabilities in the networks are imprecise. The imprecision can be handled by second-order probability distributions. It is convenient to use beta or Dirichlet distributions to express the uncertainty about proba...
