摘要
“一步测量”中 ,为了检核及提高碎部测量的精度 ,需要对已构成附合或闭合条件的加密图根点或测站点进行平差 ,然后由平差后的图根点或测站点对所测碎部点进行改正 ,再通过数字测图软件成图 .这一系列工作可在外业测量结束后 ,用计算机在室内进行自动平差和自动改正 .
In“One Step Surveying”, in order to improve the accuracy of detail surveying, we should adjust the points of mapping control or points of observation that have condition for constrained annexation or condition for closure. We should adjust the points of details according to the adjusted points of mapping control and points of observation. At last, we use surveying software to draw map. All the work can be done indoors after outdoor surveying. This article introduces the steps and the ways of outdoor operation and indoor work.
