Service Description:

This layer includes the 15', 1:62500 USGS topographic maps for Maine from the late 1800s and early 1900s, ranging from 1891-1935. There are 83 quads in this layer, covering 43% of the state, mostly southern and central Maine and Down East Maine. The maps were scanned from paper copies, georeferenced, and then had the collars clippled and the edges mosaicked. Most maps were scanned originally at 600dpi, either by MEGIS or USGS. All georeferencing of these was done by USGS. A few quads were not either in the collection of Maine or USGS, and in those cases quarter-quads were downloaded from the UNH library web site, those quarters were then georeferenced separately and if needed, rubber-sheeted along seamlines to make the quad. Most of these quads do not indicate land cover (green areas). Note that the source paper maps vary considerably in their paper color, ink contrast, fading, and so forth. The user will see great variation between quads which cannot be made more consistent at this time.
