Identification of Invasive Species Using Remote Sensing and Vegetation Indices, (Case Study: Vazroud Rangelands, Iran)
Biological invasions form a major threat to the provision of ecosystems productsand services and can affect ecosystems across a wide spectrum of bioclimatic conditions.Therefore, it is important to systematically monitor the spread of species over broad regions. Ithas long been recognized that remote sensing and geographical information system couldcontribute to this capacity. This paper aims t...
متن کاملImproving Remote Species Identification through Efficient Training Data Collection
Plant species identification and mapping based on remotely-sensed spectral signatures is a challenging task with the potential to contribute enormously to ecological studies. Success in this task rests upon the appropriate collection and use of costly field-based training data, and researchers are in need of ways to improve collection efficiency based on quantitative evidence. Using imaging spe...
متن کاملToward the identification of Frankliniella species in Brazil (Thysanoptera, Thripidae)
This paper provides an illustrated key to about 40 species of Frankliniella recorded from Brazil, together with notes about each species. Two new synonyms are established: Frankliniella longispinosa Moulton is a synonym of Frankliniella varipes Moulton; Frankliniella rodeos Moulton is a synonym of Frankliniella gemina Bagnall, all described originally from South America. One new species is desc...

متن کاملToward Scheduling Over-Constrained Remote-Sensing Satellites
The high demand for satellite imagery and the relative scarcity of commercial imaging satellites combine to produce scheduling problems in which one or more of the resources is over constrained. Over-constrained scheduling problems can be problematic for constraint programming methods because of the overhead associated with propagating constraints and the time spent backtracking over a large nu...
