Working with Site Data
Observed values or properties can be spatially referenced to a single point or, in GRASS terminology, a site. Site data represent either a discrete feature at a given scale, such as a city, an archaeological site or a hospital, or they are discrete samples of continuous fields such as data from climatic stations, measured elevation points, or bore-hole data. GRASS provides tools for management and analysis of sites map layers, as well as their transformation to vector or raster data. If the site data represent a continuous field, transformation to raster representation of this field is performed by spatial interpolation. Site data can be stored either in a multi-dimensional, multi-attribute ASCII.
