Description
Technical Field

Background
With the development of measuring instruments and the popularization of computers, the work of drawing topographic maps is gradually shifting to digital measurement and drawing. The digital topographic map measuring process includes 3 steps of field data acquisition, data processing and computer drawing. The field data acquisition equipment and computer drawing software have been developed more mature. But due to the diversity of field data acquisition equipment and the complexity of landforms, the acquired data has diversity; computer drawing software usually defines a uniform data format to facilitate computer drawing; the data collected by field industry needs to be converted into the data format of computer drawing software to realize computer drawing. Currently, there are two ways for industry to collect data processing: marking the sequence of field collected data and the ground feature characteristics by a sketch method and recording related data; and after the collection is finished, the data is arranged into a format required by computer drawing software by using a table. The method has the defects of complicated data acquisition process, low acquisition speed, large workload of field data processing and high error rate. And secondly, a simple code method is adopted, namely, data are stored according to the requirements of computer drawing software on data reading sequence, data coding and data characteristics when the data are collected. The method also has the defects of complicated data acquisition process, low acquisition speed and incapability of processing the data into a data format required by computer drawing software at one time.
For example, the common CASS computer drawing software in hydraulic engineering measurement has unique coding requirements and data format and sequence requirements on data recorded in the software. At present, in practical application, field operating personnel is required to memorize various ground object codes in CASS computer drawing software skillfully, and when data are acquired, the ground object codes corresponding to each measuring point and the data are stored in data acquisition equipment together, so that the data acquisition process is complicated, and the acquisition speed is low. Secondly, the CASS computer drawing software code can only use a plus sign to represent a code connected with the previous point, so that the ground object measurement must be carried out by 'vertical ruler' one by one, when a plurality of ground objects need to be measured, the 'vertical ruler' measurement cannot be crossed, the working efficiency is low, and the missing measurement is easy to occur.
