The Lakeville quadrangle's imagery credits, 2008–2016; first-coverage residue named
The photographic map of this ground can be dated by its own credits, and the dated run is printed here from the sheets themselves. The USGS US Topo editions of the Lakeville quadrangle — the town's topo sheet of record, per the maps file — carry their photographic basis in their collars: the 2010 edition rides on National Agriculture Imagery Program imagery of August 2008; the 2013 edition updates to NAIP imagery of June 2012, with roads, names and hydrography layers redated around it; a 2016 edition follows in the same series. The photographic map is therefore not one picture but a dated series of flights, and Lakeville's ground is re-photographed on the federal cycle whether the town notices or not — the imagery is the map now, the contours and names a commentary on it. The county GIS's aerial layers ride on the same federal and state flights. Residue, named plainly: the first aerial coverage of this ground — the agricultural survey flights of the late 1930s and 1940s that begin most Indiana counties' photographic record — was not dated for Lakeville from the USGS EROS coverage record in this section, and that record, the audit's settler, stands current as the item's named residue. This item closes mixed: the modern photographic series dated from its own credits, the first flight undated rather than guessed.
