NRS-20981 | Visual Index Maps [Land and Property Information New South Wales]

Records consist of standard topographic hard copy maps with notations of the intended surveys and completed surveys allocated recorded plan numbers and the extent of the survey. A paper index sheet was glued to the map to form the key. The index maps were kept in alphabetical map name order. The topographic map numbers were used as the individual record identifiers. This has become the record number for the maps. The maps were used as a spatial index of the Recorded Plans in a given geographical area. By using the index it could be seen what plans were intended and completed then to refer to the Record Plan number to view the Recorded Plan and access the data for control survey marks. The Visual Index ceased to be used once details were transferred to the Survey Control Information Management System (SCIMS)database.The series is arranged alphabetically by map name and then by topographic map number.

本数据集收录标准纸质地形图，图上标注有拟实施测量与已完成测量的相关信息，并配发存档图号（recorded plan numbers）及测量范围。每张地形图均粘贴纸质索引页，作为该地图的检索主键；索引地图按地形图名称的字母顺序进行存放管理。地形图编号被用作每条记录的唯一标识符，此后该编号即成为该地形图的记录编号。此类地形图可作为特定地理区域内存档测量图纸（Recorded Plans）的空间索引，通过该索引可快速查询到已规划及已完成的测量图纸信息，随后可通过存档图号调取对应存档图纸，并获取控制测量标志的相关数据。当相关信息迁移至测量控制信息管理系统（Survey Control Information Management System, SCIMS）数据库后，该视觉索引便不再投入使用。该数据集系列先按地形图名称的字母顺序排序，再按地形图编号进行二次排序。
