An instrument used for plotting straight lines and measuring angles on a CHART or PLOTTING SHEET. See PROTRACTOR. In data processing it stands for (a) Vector plotter: An electromechanical device for automatically drawing curves. The curves are generated by a sequence of linear incremental pieces ("vectors") depending on the resolution provided by the device. For cartographic purposes, high precision FLAT-BED PLOTTERS (drawing tables) are used. (b) Raster or electrostatic plotter: A sophisticated electronic device for producing pictures by means of raster techniques. The picture is generated by lines of PIXELS drawn sequentially, typically with a resolution of 200-400 pixels per inch. Raster plotters can produce complete pictures in short time irrespective of the complexity of the picture's contents.

用于在海图或空白海图上标绘直线并测绘角度的仪器。参见protractor(量角器)。 在数据处理中是指(a)矢量绘图机:一种可自动绘制曲线的机电装置。该曲线由一系列线性增值线段(“矢量”)所组成,这些线段是由该装置的分辨率决定的。制图使用的是高精度平台式绘图机(绘图台)。(b)光栅或静电绘图机:一种通过使用光栅技术生成图形的复杂的电子装置。该图形由连续绘出的成排像素组成,一般分辨率为每英寸200-400个像素。光栅绘图机无论地图内容如何复杂,均可在短时间内生成完整的图形。
