摘　　要：介绍了公路设计与施工测量中,由于投影引起的长度变形与实地平距不一致,超出规定时,利用坐标投影边长归化数学转换关系,建立独立坐标系,并确保独立坐标系与原设计比例尺的图件及数据融合,达到"一张图"的精度要求。In the highway design and construction survey, the projection of length of deformation caused inconsistent with field horizontal distance. When the difference beyond the provision,we used coordinate projection length of naturalization mathematical conversion relationship to establish independent coordinate system, and ensured the establishment of independent coordinate system and the original design scale maps and integration.

关 键 词：独立坐标系 投影 长度变形 控制测量
