Knowledge Discovery From Multispectral Satellite Images, Arun D. Kulkarni Sep 2004

Knowledge Discovery From Multispectral Satellite Images, Arun D. Kulkarni

Arun Kulkarni

A new approach to extract knowledge from multispectral images is suggested. We describe a method to extract and optimize classification rules using fuzzy neural networks (FNNs). The FNNs consist of two stages. The first stage represents a fuzzifier block, and the second stage represents the inference engine. After training, classification rules are extracted by backtracking along the weighted paths through the FNN. The extracted rules are then optimized by use of a fuzzy associate memory bank. We use the algorithm to extract classification rules from a multispectral image obtained with a Landsat Thematic Mapper sensor. The scene represents the Mississippi …

Empirical Study On Location Indeterminacy Of Localities, Sungsoon Hwang, Jean-Claude Thill Dec 2003

Empirical Study On Location Indeterminacy Of Localities, Sungsoon Hwang, Jean-Claude Thill

Sungsoon Hwang

It is often the case that locality boundaries are not sharply delineated in our mental maps. This paper examines the level of uncertainty involved in perceiving qualitative boundaries of urban vs. rural localities. To measure location indeterminacy of locality, we begin with modeling locality as fuzzy region or also known as egg-yolk model which is composed of core, boundary, and exterior. The more a specific locality (e.g., Buffalo, Amherst) is geocoded within core, the more locality is location-determinant. 5460 fatal traffic accidents gathered from the Fatality Analysis Reporting System (FARS) in New York State from year 1996 to 2001 are …

Public Commons Of Geographic Data: Research And Development Challenges, Harlan Onsrud, Gilberto Camara, James Campbell, Narindi Sharad Chakravarthy Dec 2003

Public Commons Of Geographic Data: Research And Development Challenges, Harlan Onsrud, Gilberto Camara, James Campbell, Narindi Sharad Chakravarthy

Across the globe individuals and organizations are creating geographic data work products with little ability to efficiently or effectively make known and share those digital products with others. This article outlines a conceptual model and the accompanying research challenges for providing easy legal and technological mechanisms by which any creator might affirmatively and permanently mark and make accessible a geographic dataset such that the world knows where the dataset came from and that the data is available for use without the law assuming that the user must first acquire permission.
