| 摘 要： | 本文介绍了一种高效的基于摄影测量数据库的数字测图系统，该系统由数据采集、图形编辑和处理、绘图数据处理以及作为主体的数据库管理等四个子系统组成。用户可在国产解析测图仪ＡＰＳ—１和经过数字化改造的模拟测图仪器上进行数据采集，通过交互式图形编辑和摄影测量处理以形成１：５万摄影测量数据库数据，并输出线划地形图，具有对该数据库数据的检查、验收功能。此外，本文还研究了等高线内插的若干算法，形成了较为实用的等高线内插软件包。

| Abstract: | An efficient photogrammetry- based digital plotting system is presented in this paper. which falls into such four subsystems as data collecting. graphics editing & processing. plotting and dominant database management subsystem. The data can be aquired from analytical plotter APS- 1 and computer-surpported analog plotters. The data 1: 50000 topographic database are formed through the interactive edditting of graphics and photogrammetric processing.The data check- up function of the database is realized in Microsoft C.Several algorithms of the contour interpolation have been studied. A practical software package on contour Interpolation is implemented. |
