Applicability of noaa/avhrr imagery in mapping forested areas along the yenisey meridian
TLDR
In this paper, a team of Russian forestry scientists examined the applicability of NOAA/AVHRR satellite imagery in further development of methods for mapping forested areas and evaluated the accuracy of automated supervised classification maps (maximum likelihood method) by comparison with conventional maps at a wide variety of scales.Abstract:
A team of Russian forestry scientists examines the applicability of NOAA/AVHRR satellite imagery in further development of methods for mapping forested areas Summertime images processed in IDRISI for an area bounded by 48° and 71°N and 86° and 98°E were analyzed The accuracy of automated supervised classification maps (maximum likelihood method) was tested by comparison with conventional maps at a wide variety of scales Special emphasis is placed on examining prospects for expanded use of NOAA/AVHRR imagery in solving problems related to global climate change: displacement of vegetation zones, change in forest productivity, and phenology of forest vegetation developmentread more

A coefficient of agreement as a measure of thematic classification accuracy.
TL;DR: In this article, a conditional coefficient of agreement for individual categories is compared to other methods for expressing category accuracy which have already been published in remote sensing literature, such as a Coefficient of Agreement as a Measure of Thematic Classification Accuracy.

Satellite remote sensing of primary production: comparison of results for Sahelian grasslands 1981-1988
TL;DR: In this paper, field measurements of primary production in semi-arid grasslands in three Sahelian countries over a period of 8 years were analyzed in conjunction with multitemporal sums of vegetation indices derived from the NOAA spacecraft's advanced very high resolution radiometer (AVHRR).

TL;DR: In this article, the authors propose to use a small number of vegetation characteristics that either are related to or closely related to the functional controls to capture mixtures and gradients in vegetation within the cell size of the model.

Remote sensing of tropical forests : an overview of research and applications using non-photographic sensors
TL;DR: In this paper, a comprehensive overview on how remote sensing technology has been applied to tropical forest monitoring over the past 20 years is presented, along with discussions on the use of Geographic Information Systems, and multistage and multisensor approaches in data analysis and acquisition.
