NORGES SVALBARD og Ishavs-undersokelser, now known as Norsk Polarinstitutt, has begun the issue of a detailed map of Svalbard in folded sheets, each covering about 1,300 kilometres. The scale is 1 to 100,000. The map is based on a network of trigonometrical points and constructed from aero-photograms taken by oblique photography. It is in black for moraines, glacier limits and lettering, blue for seas, streams, lakes and glacier contours, brown for form lines and contours, and green for glacier slopes. In addition to the old place names in their accepted Norwegian forms, a number of new names have been added. The first sheet (price 3 kroner) covers the little-known Sorkapp area as far north as Hornsund and is numbered C.13.
