| Scale (measurement) |
a system used to encode the results of a measurement; typically a number line, but generalized to include a list of categories. |
| Slope |
a multicomponent property associated with a surface at each point; the vertical component (gradient) expresses the local rate of change, the horizontal component (aspect) gives the direction. |
| Soil inclusions |
a category of soil expected to occur inside the units mapped as another category. |
| Spatial autocorrelation |
degree of correlation between a surface value and the values of its neighbors; propensity of spatial data to vary smoothly. |
| Spatial object framework |
a measurement framework that identifies a particular category, then maps the location of that object (as a point, a line or an area). |
| Spatial reference system |
a mechanism to situate measurements on a geometric body, such as the Earth; establishes a point of origin, orientation of reference axes, and geometric meaning of measurements, as well as units of measure. [basis of coordinates.] |
| SQL |
Structured Query Language; a standard interface for access to a relational database through queries that select records matching logical expressions. |
| Surface |
a spatial distribution which associates a single value with each position in a plane; (technically a field of a single-valued function) usually associated with continuous attributes. |
| Scanner |
A device for converting images from maps, photographs, or from part of the real world into digital form automatically. |
| SPOT |
An earth resource satellite with high resolution sensors launched by France in January 1986. |
