DataSetInfo.EstimatedScale Property
Gets or sets an estimate of the view scale appropriate to display the data.
Syntax
public System.Double EstimatedScale { get; set; }Property Value
Default: 0.0
An estimate of the view scale appropriate to display the data.
Remarks
For raster data, this scale is based on the resolution of the rasters. If the root node has children with different estimated scales, it is your responsibility to choose the highest, lowest, or some average, or to decide if the data should be divided into several distinct datasets.
For vector data, this scale is usually based on the file size and the bounds area, assuming a desired amount of data megabytes per screen area. This gives a coarse estimate that can be wrong by a factor of 10 or more, but is useful as a first attempt. However, for some vector data formats, for example VPF, the intended scale is retrieved from available metadata.
A value of zero for this scale is of course not useful, and means that a sensible value could not be calculated.
