A Source Feature is the mapped representation of one or more observations, including Locational Uncertainty to ensure that the actual on-the-ground location of the underlying observation(s) is captured within the Source Feature.
Creation of a Source Feature requires an interpretive process. The likely location and extent of an observation is determined through consideration of the amount and direction of any variability between the recorded and actual locations of the observation data. The Source Feature is delineated to encompass Locational Uncertainty.
A Source Feature can be a point, line, or polygon. The type of Source Feature developed depends on both the preceding Conceptual Feature Type and the Locational Uncertainty Type associated with the feature.
