Vector CTRN 1:50,000 (1991-1995) — Level curves — HISTORY
Description
Vector CTRN 1991-1995 1:50,000: Vector data of the Regional Numerical Technical Charter (CTRN) at the 1:50,000 scale derived automatically as a generalisation of the 1:10,000 CTRN acquired by the Piedmont Region’s cartographic service in the years 1992-1997. Unlike the original numerical data organised into lines, dots, polygons and texts, broken down by CTR section, these data are organised into thematic levels, such as CTRN data 1:10,000..Level Curves: Altimetry represented in linear form (level curves at constant altitude), with certain or uncertain determination.
