    6666== Distance Lookups ==
    6767Distance lookups are supported on both PostGIS and Oracle.  Each distance lookup type takes a tuple parameter comprising (1) a geometry to base calculations from and (2) a number or `Distance` object containing the distance.  If a `Distance` object is used, it may be expressed in any units (the SQL generated will use units converted to those of the field); otherwise, numeric parameters will be assumed to be in the units of the field.
