The data were projected to Lambert Conformal Conic. One label was added to each polygon. Internal logical consistency checks were made as described in the logical consistency report. This data set was used to generate updated arcs and tics for data sets QUAD75, QUAD15, QUAD100, and QUAD250. There are no user-defined polygon attributes.
Values are in decimal degrees.
Q75 - Indicates if arc is a boundary for a 7.5 minute quad. Q100BASE - Defines 30x60 min. Q250BASE - Defines 1 x 2 degree quadrangle boundaries for cartographic use. These boundaries differ significantly from the typical rectangular quadrangle shape. DNR makes no guarantee or warranty concerning the accuracy of information contained in the geographic data.
