GIS-models are increasingly used to assess habitat preferences and distribution of target species, but their accuracy is constrained by availability of digital data layers.
The increased spatial mapping accuracy of Constrained Spectral Conditioning is shown for a simulated dataset of point sources which vary in strength.
In this paper, we correct some of the conceptual errors in the literature on identification ROCs, and demonstrate their value for both understanding the factors that influence eyewitness identification accuracy and constraining theoretical development.
Sampling intensity and taxonomic expertise severely constrain accuracy of seaweed mapping and floristic data, as well as notions of abundance and rarity.
Results for assignment to genus using random versus constrained sampling of sub-libraries were very close in terms of overall accuracy, with constrained having slightly lower overall accuracy across all completeness levels.
Constrained versions of these models all produced similar accuracy regionally, but constrained and unconstrained versions of the SMA5 model best captured fc for the rarer landscapes (bright soils, riparian vegetation) found throughout the region.
Moreover, it would not face the problems that constrain the accuracy of curved lenses and so could make a perfect lens.Unfortunately, the only material with a negative refractive index to be developed so far worked only at wavelengths very much longer than those of visible light.
These azimuthal gap values are sufficient to constrain location accuracy for these events as the largest azimuthal gap is, at worst, 180° as also specified by several authors such as Engdahl et al. (1998, 2007).
