Orthophoto Image Mosaics
About the mosaics
The quadrangle-based images cover an area of 7.5 minutes of latitude and longitude, corresponding to the quadrangle maps published by the United States Geological Survey and the New York State Department of Transportation. Each quad consists of sixteen tiles, although certain mosaics contain extra tiles where the image area extends across the quadrangle edge. Furthermore, tiles may be missing for large areas within a quadrangle lying outside of New York State. The mosaics are presented at a resolution of 8 meters per pixel, reduced from the original 1 meter resolution of the tiles. Actual map scale will vary depending upon the user's display settings. The quadrangle-based mosaics are essentially the same format as USGS orthophotoquads, although they lack the minimal cartographic treatment found in the latter.
The metropolitan area mosaics are made up of whole or
partial quadrangles, usually presented at 16 meters per pixel (one-half
size of the quadrangle-based mosaics, or one-sixteenth the size of the
original tiles). Because of their lesser resolution, the metro area
mosaics show a larger ground area in a proportionately smaller file
size than the quadrangles. The metropolitan area images show the
immediate vicinity of a major city or larger metropolitan area in New
York State. Some of these mosaics have been augmented with USGS imagery
to show adjoinging areas outside of the State.

New York State Maps
Counties: This map shows boundaries and names for all 62 counties in New York State. Clicking on a county will take you to the Empire State Roads route listing for that county.
County Seats: This map shows the seat of government for each county. This is usually a City or Village, but a few are unincorporated localities; one county's seat (Warren) is considered to be a Town (Queensbury). Although the main county offices may not be located precisely within the municipality named, these are nevertheless the official, or traditional, county seats.
Cities: New York State has sixty-two Cities, shown here. They range in population from less than three thousand to over seven million, although most are between ten and thirty thousand. Cities are not the only large municipalities in the State: the largest Village, Hempstead, is more populous than all but twelve of the true Cities, and a few unincorporated places are larger still. Also available is a list of all the Cities, arranged by population (1990 census).
Villages: As of 1998 there are 554 incorporated Villages in New York. This map locates each with a dot (larger dots show Cities, smaller dots are used for villages in Rockland, Westchester and Nassau Counties because of scale). Four of the Villages in the State are coterminous with Towns and have special combined forms of government. Villages range in population from 28 persons (Dering Harbor) to nearly fifty thousand (Hempstead); most contain between 250 and 1,000 persons with larger villages reaching 5,000 or more.
Towns: All of the land in New York State lies in either a Town or a City, never both. While not all counties contain Cities, all except the five boroughs of New York City do contain Towns, and these are outlined on the map. Cities are shown on this map by a grey tint, with lighter grey depicting the lower tax areas of the Cities of Oneida, Rome and Saratoga Springs (this functions like a City surrounded by a Town, with the government of the two merged to form a single entity).
