Classifying and Mapping Wildfire Severity

Autor: Mark Mangrich, C. Kenneth Brewer, David W. Opitz, Roland L. Redmond, J. Chris Winne

Publikováno v: Photogrammetric Engineering & Remote Sensing. 71:1311-1320

This study evaluates six different approaches to classifying and mapping fire severity using multi-temporal Landsat Thematic Mapper data. The six approaches tested include: two based on temporal image differencing and ratioing between pre-fire and po

Forest fragmentation may cause increased brood parasitism and nest pre- dation of breeding birds. In North America, nest parasitism and predation are expected to increase closer to forest edges because the brood-parasitic Brown-headed Cowbird (Mol- o

The time and effort required of probability sampling for accuracy assessment of large-scale land cover maps often means that probability test samples are not collected. Yet, map usefulness is substantially reduced without reliable accuracy estimates.

Estimation and Mapping of Misclassification Probabilities for Thematic Land Cover Maps

Autor: J. Chris Winne, Roland L. Redmond, Brian Steele

Publikováno v: Remote Sensing of Environment. 66:192-202

There is abundant evidence that thematic map accuracy may vary across a landscape in a manner that is only partially related to land cover type. Spatial variation in accuracy may be attributable to factors such as terrain, landscape complexity, and l

Demography of Bristle‐thighed Curlews Numenius tahitiensis wintering on Laysan Island

Autor: Roland L. Redmond, Jeffrey S. Marks

Publikováno v: Ibis. 138:438-447

We studied the nonbreeding ecology of Bristle-thighed Curlews Numenius tahitiensis from 1988 to 1991 on Laysan Island in the Northwestern Hawaiian Islands. Using capture-recapture analysis, we estimated that 300–350 curlews wintered on the island.

Conservation problems and research needs for Bristle-thighed Curlews Numenius tahitiensis on their wintering grounds

Autor: Jeffrey S. Marks, Roland L. Redmond

Publikováno v: Bird Conservation International. 4:329-341

SummaryThe Bristle-thighed Curlew Numenius tahitiensis is a rare shorebird that breeds in western Alaska and winters on oceanic islands in the tropical and subtropical Pacific Ocean. Before human colonization, the islands on which curlews winter were

Migration of Bristle-Thighed Curlews on Laysan Island: Timing, Behavior and Estimated Flight Range

Autor: Roland L. Redmond, Jeffrey S. Marks

Publikováno v: The Condor. 96:316-330

Bristle-thighed Curlews (Numenius tahitiensis) fly at least 4,000 km non-stop from staging grounds in western Alaska to the northern edge of the winter range at Laysan Island in the Northwestern Hawaiian Islands. Adults migrate from Laysan in early M

A discriminant space-based framework for scalable area-class mapping

Autor: Roland L. Redmond, Jingxiong Zhang, Michael F. Goodchild, Brian Steele

Publikováno v: SPIE Proceedings.

Earlier research has introduced the concept of discriminant space, which is spanned by the covariates underlying area-class occurrences, for increased consistency, interpretability, and replicability in area-class mapping and uncertainty characteriza

Generalized linear models for mapping land cover using satellite measurement and digital terrain data

Autor: Jinping Zhang, Brian Steele, Roland L. Redmond, Xiong Rao

Publikováno v: SPIE Proceedings.

This paper explores an approach for predicting land cover types of central Montana, USA based on satellite measurement and digital terrain data. We assume a non-linear inherent relationship existing between land cover types and Landsat TM reflectance
