本文综合文献[1]中的组合编码方案和文献[2]中的纯数字编码方案,依据现在测量仪器默认编码为上一编码的习惯,充分利用外业采点数据的顺序,研究设计一种全数字的外业数据采集属性输入的编码方案。如果将编码为默认属性即不用手动输入,看做编码位为0,使用此方法进行外业数据采集,每个地物的编码输入平均不到2位;并且此方案解决了同一测点具有两个属性时需要采集两次的问题。 Based on the combined coding scheme in [1] and the pure digital coding scheme in [2], based on the current coding instrument’s default coding as the previous coding convention, this paper makes full use of the sequence of field data mining to study and design a All-digital field data acquisition attribute input coding scheme. If the code is the default property that is not manually entered, as the encoding bit is 0, the use of this method for field data acquisition, each feature an average of less than 2-bit code input; and this program to solve the same test point with two Attributes need to collect twice the problem.
