Uses of rainfall spectrum data

The scientific interest in rainfall spectrum (its drop size distribution, DSD) is double. On one hand it provides information about cloud physics and rainfall generating processes. On the other hand, the DSD controls relevant rainfall properties such as its kinetic energy (relevant for soil erosion studies), the reflectivity of microwaves (relevant for the remote sensing […]

Towards the implementation of a vector data type in GIS

In contrast to scalars, which only have magnitude, vectors are geometrical objects defined by a magnitude and a direction. They play an important role in physics, since they can represent the forces acting on a body, velocities and accelerations, etc. In Geographic Information Science (GIS) analysis we are used to work with scalar fields, h(x,y), […]
