A single geocoded data layer is created by converting centroid related
data to a line by adding or subtracting a distance at a predetermined
direction from the centroid to derive an endpoint from the centroid
defining the line (taking the form of a radial extending from the
centroid). The source of the centroid related data is utilized to
determine the direction of the line. The single geocoded data layer
allows for one pass searching of geocoded data, and provides a display
with more information than a simple match to a point or centroid. The
radial display may take any form. Unconfirmed locations in the database
may be related only to a centroid, and a display program automatically
calculates a radial for display in conjunction with the centroid. The
display may be the form of a radial, a radial with notches (representing
additional matches), colors, or other shapes, etc.
