Continuous Data Usually a reference to grid or raster data representing surface data such as elevation. In this instance, the data can be any value, positive or negative; sometimes referred to as real data. In contrast, see discrete data.
continuous data
Data such as elevation or temperature that varies without discrete steps.

In contrast, see continuous data. Dot map Simple thematic technique using dots to show the spatial distribution of a chosen element. One dot usually represents a specified number of the mapped element.
The majority rule was used to assign USLE factor values to cells for discontinuous data such as soil erodibility and the centroid value was assigned to each cell for continuous data such as the topographic factor.
Raster data are especially suited to continuous data. Continuous data change smoothly across a landscape or surface.
At the other extreme, we often need to collect continuous data on the ground at widely separated stations or over extended time periods, often in inaccessible areas.
The bilinear and cubic interpolation methods are most appropriate for continuous data and cause some smoothing. Both options should not be used with categorical data, since the cell values will be altered.
For example, the vector data model does not handle continuous data, e.g. elevation, very well while the raster data model is more ideally suited for this type of analysis. Accordingly, the raster structure does not handle linear data analysis, e.g.
Most analyses combine these layers to create new layers with new cell values, as either continuous or discrete data. Continuous data types have gradations, such as temperature or elevation.
Raster data is best suited for continuous data such as slope, rainfall, or the amount of light reflecting off the ground (as in a photograph). Aerial photographs and satellite images are examples of raster images used in mapping.
This concept can be applied to other spatially continuous data as well. For instance, population density or income levels could be mapped as a third dimension to support demographic analysis or water consumption statistics.

ArcSDE enables organizations to move from a traditional approach - managing a separate collection of geographic data files - to an integrated environment in which spatial data is managed as a continuous database that is accessible to the entire ...
at higher elevations, varying greatly even within one valley or watershed, current remote-sensing snow monitors do not supply adequate data. Further, snow may be redistributed by wind, avalanches, and non-uniform melting, so that continuous data ...
continuous data A surface for which each location has a specified or derivable value. Typically represented by a tin or lattice (e.g., surface elevation). contour A line connecting points of equal surface value.
