近几年,不少工程勘察单位在制图方面有不少革新,并在生产实践中积累了宝贵的经验。有的单位自力更生制造了复印机,如重庆市设计院勘测队试制了勘测制图缩放静电复印机、济南市城建勘察测量队试制了简易静电复印机,将静电复印技术应用于制图、编图,简化了成图工序,缩短了成图周期,降低了成图成本。有的单位改进了制图的工艺,如广西区地质局测绘队用晒印法复制图件,提高了成图质量。现将这些革新成果简介如下:
In recent years, many engineering survey units have made many innovations in drawing and have accumulated valuable experience in production practice. Some units made self-reliant copiers. For example, the survey team of Chongqing Design Institute produced a surveying and mapping scaled electrostatic copier, and the Jinan city construction survey and measurement team produced a simple electrostatic copier. The electrostatic copying technology was used for drawing and editing, simplifying the mapping. The process shortens the drawing cycle and reduces the cost of mapping. Some units have improved the drafting process. For example, the mapping team of the Guangxi Geological Bureau used the printing method to copy the maps and improved the quality of mapping. Now these innovative achievements are described as follows:
