Filtering by Parameters in the File. Comparator (>, =,
or <) qualification of selected parameters may be used to
limit lake retrieval with or without specifying a specific
geographic locality. The lakes which have not been up
dated will have zeros filling all fields except those
calculated by the computer identification system.
The parameters that may be used in combination for limiting
lake retrieval are: geographic quadrangle; lake surface
area; free water area below ice; conductivity; presence or
absence of fish; presence, absence, or % area of vegetation;
and presence or absence of inlets and/or outlets. Com
parators are used in combination with a limiting value or
with yes or no qualifications to limit the properties listed
above for filtering out lakes of no interest. Lakes of
interest are then listed in computer-formatted tables.
