Two demonstration sites in southeast Idaho were used to extend the scope of remote sensing of leafy spurge research toward investigating coarser scale detection limits. Hyperspectral images were obtained to produce baseline leafy spurge maps, from which spatially and/or spectrally degraded images were subsequently derived for comparative purposes with Landsat 5 Thematic Mapper (TM). The baselin...

This paper describes the application of SAR texture in classifying examples of Amazon rain forest into forest and not forest categories. The results are compared with corresponding classification of Band 5 Landsat TM imagery.

Landsat TM has provided a continuous stream of data over several decades at a moderate resolution suitable to extract land based information. Landsat 5 TM being in orbit for almost 25 years, far exceeding design expectations has degraded significantly in its spectral properties. Although new methods for the determination of calibration parameters have been published several years ago (Chander &...

The main goal of this study was to quantify within and between field variability in mapping agricultural crop types, their biophysical characteristics, and yield for precision farming applications using near-real-time and historical (archival) Landsat TM images. Data for 6 crops (wheat, barley, chickpea, lentil, vetch, and cumin) were gathered from a representative benchmark study area in the s...

Remote sensing provides a useful tool for mapping invasive species across large areas. This study compared the effectiveness of imagery derived from three multi-spectral (Landsat Thematic Mapper (TM), SPOT 5, and Quickbird) and hyperspectral (Hyperion) imaging platforms for detection of the invasive species Lantana camara L. in eastern Australia. Landsat TM multispectral (MS) image provided an ...
