PE&RS January 2001

Cover Image
This month’s cover is an illustration of flame front mapping done during the recent Montana wildfires. The mosaic was done by the University of Montana’s remote sensing lab using data provided by an Airborne Data Systems Spectra-View® 5-band system. It is an illustration of true color, laid under the 3-5 micron thermal band. In addition to these 4 bands, there is a near infrared band (NIR) not shown. This map was created using ERDAS IMAGINE® software package.

49 Non-Differential GPS as an Alternative Source of Planimetric Control for Rectifying Satellite Imagery
Jay Gao

Uncorrected GCP coordinates averaged from as few as 30 loggings can be used as a reliable alternative source of planimetric control in rectifying coarse-resolution satellite images of Earth resources in a first-order polynomial transformation. 

57 An Edge-Preserving Filter for Imagery Corrupted with Multiplicative Noise
H.C. North and Q.X. Yu

Speckle noise in synthetic aperture radar data is effectively reduced, and yet clean, continuous feature boundaries are retained in the filtered image. 

65 An Uncertainty-Based Method of Photointerpretation
Benoît Thierry and Kim Lowell

The method, in which only those features that an interpreter believes to be “100 percent certain” are identified, provides considerable time savings and also provides an estimate of the certainty of the photointerpretation. 

73 Spatial Prediction of Fire Ignition Probabilities: Comparing Logistic Regression and Neural Networks
Maria José Perestrello de Vasconcelos, Sara Silva, Margarida Tomé, Margarida Alvim, and José Miguel Cardoso Pereira

The logistic models have better concordance than do the neural networks in the training phase; however, the neural networks show higher overall classification accuracies. 

83 Measurement and Monitoring of Urban Sprawl in a Rapidly Growing Region Using Entropy
Anthony Gar-On Yeh and Xia Li

An entropy method that integrates remote sensing and GIS for the measurement and monitoring of urban sprawl in a rapidly growing region is presented. 

91 An Automatic Method for Vine Detection in Airborne Imagery Using the Wavelet Transform and Multiresolution Analysis
Thierry Ranchin, Bernard Naert, Michel Albuisson,  Gilbert Boyer, and Pär Åstrand

A fully automatic vine detection method from airborne IRC images using spectral and spatial information is proposed. 

99 Integration of Aerial Remote Sensing, Photogrammetry, and GIS Technologies in Seagrass Mapping
Vanina Pasqualini, Chistine Pergent-Martini, Philippe Clabaut, Hervé Marteel, and Gérard Pergent

The comparison of cartographic and bathymetric data, brought together in a geographic information system, allows the spatial distribution of seagrasses to be evaluated for the first time. 

107 CAD-Based Object Reconstruction Using Line Photogrammetry for Direct Interaction between GEMS and a Vision System
Guoqing Zhou and Deren Li

The geometric elements which describe industrial objects are taken as unknowns and are directly solved for by matching images (2D) and objects (3D).
