A logical consistency report is not applicable to raster data sets. Complete topographic representation. The digital GeoTIFF version of the historical map was georeferenced with a methodology that preserves, but does not exceed, the accuracy of the original map. The historical map product was compiled to meet National Map Accuracy Standards (NMAS) of the era when the map was originally published. USGS 1954 Original Paper Map Keweenaw Bay, MI; U.S. Department of the Interior, USGS Scanned Historical Quadrangle Standard, Version 1.0. 62500 paper 1954 publication date map USGS provided the scanned copy of the historical quadrangle. The GeoTIFF for the scanned Historical Quadrangles are produced using the following steps. Historical Quadrangles are scanned typically at 600 PPI (minimum of 400 PPI). Metadata is collected from the information printed in the map collar. Scanned TIFF images are georeferenced to the original map datum, and reprojected to the original map projection. The final GeoTIFF file is downsampled to 300 PPI, compressed, and zipped with an external metadata file.
