Contours - 5 metre - Queensland series (Historic)

This data is a historic collection of 5 metre contours covering South East, Central and North Queensland. The original datasets that these dataset has been compiled from were captured over an extended period of time using photogrammetric methods. Attributes within the data describe the age and resolution of the source imagery that the original datasets were captured from. The data was generally captured to 1:25000 mapping specifications with a 5 metre contour interval.本数据集为涵盖昆士兰州东南部、中部及北部的历史型5米等高线（5 metre contours）数据集。本数据集所整合的原始数据集，系通过摄影测量法（photogrammetric methods）历经较长周期采集所得。数据内的属性字段可描述原始数据集采集所用源影像的年代与分辨率。该数据集整体遵循1:25000比例尺制图规范，等高距为5米。
