 the pixel density the resulting lineofsight coverage should have. This is the

will increase linearly with this density.aSampleDensity

longitude, for grid target references this is usually (depends on the unit of measure of the reference) the
average number of samples per meter square. From this parameter the radial and angular step for sampling are
computed. The higher the density, the more accurate the result will be, but computation time will de/increase
linearly with sample density. Note that this does not influence the density of the resulting raster, a higher
sampling density will provide more data for one pixel of the raster. Which of these value is chosen depends on the
fill mode parameter. Reasonable values are usually the densities of the underlying rasters, provided they have
the same reference as the target reference.aRadialFraction
 a number in the interval ]0,1] which indicates up until which fraction of aMaxradius every
pixel of the result should be represented by at least one computation. Even when the fill mode is not equal to
nearest neighbor it is guaranteed that there will be no 'holes' in the raster up until this fraction. Computation
time will de/increase linearly with the radial fraction.aFillMode
 how the raster should be filled. Possible choices are:
aAltitudeMode
 the altitude mode expresses whether the result should be interpreted
as height above ground, above geoid or above ellipsoid. If null is
passed, above ground is assumed.aKFactor
 a factor indicating the reflection of radar waves on the atmosphere.
For radar computations, values should be greater than 1, usually 4/3.
