3.10 Rough Pasture
Figure 16: Typical Rough Pasture Area Image
This part of the study focuses on areas of land cover known as rough pasture.
They correspond to areas where scrub/ mixed forestry or overgrown vegetation are
present. In general terms it could be used to refer to areas of bad pasture but could
also be found close to an urban area where the land is not in use. It is similar to
mixed forestry but would be slightly lighter than forested areas (and returned
spectral values accordingly –by app 75 across all colour bands). The values for
this type of coverage could be particularly useful in determining whether the
target polygon was in use or not. The results from the sample areas returned a high
level of deviation from the mean value in both the red and green colour bands.
This would not be expected where the land was in use. If the polygon being
examined was not part of an urban development (comprising of a mixture of
artificial and landscaped surface cover) and was in use then a relatively low level
of deviation form the mean value would result from human activity –for example;
the results from a study of polygons used for pasture in this survey returned a
deviation of almost one quarter of what was found here.
