Catalog of available clear mylar templates used to determine latitude and longitude of sample localities between the latitudes of 51 degrees 00‘ and 71 degrees 30‘ at the scale of 1:63,360 and between the latitude of 49 degrees 00‘00" north or south at the scale of 1:250,000

Abstract:

The present use of electro-mechanical plotting of sample points can give rise to location errors, particularly when map scale changes are involved, unless careful control is maintained. The following catalog of computer-generated mylar templates, with plots of latitude and longitude (longitudes equidistant north to south), sufficient to cover the latitudes between 49?00‘00‘‘ and 71?30‘00‘‘ N. or S., will help facilitate the plotting of points when there is a map scale change for two different map scales (1:63,360 and 1:250,000). Using the template overlays (available as individual page numbers in Open-File Report 82-724--xerographic clear film overlays from U.S. Geological Survey Open-File Services Section, Branch of Distribution, USGS, Box 25425, Denver, Colorado 80225, telephone (303) 234-5888), the point plotted on a composite final copy may be checked against field maps and notes when only degrees latitude and longitude are given.
