Digital mapping method

Abstract

The invention relates to a digital mapping method, comprising the following steps: (1) starting a total station, a smart phone and a receiving device respectively; (2) enabling the smart phone to search a Bluetooth communication device of the total station and connect with the total station, and setting communication parameters; (3) setting a coordinate on the total station and carrying out on-site mapping to obtain X / Y / Z coordinate data which describe the topography; and storing the coordinate data and transferring the coordinate data to the smart phone by the Bluetooth; (4) drawing a mapping draft in the smart phone and storing in binary format to obtain draft data; (5) compressing the draft data and transferring the compressed draft data to the receiving device by SMS or GPRS; (6) compressing the coordinate data and transferring the compressed coordinate data to the receiving device by SMS or GPRS; and (7) enabling the receiving device to draw by a topographic map drawing software to obtain a topographic map. The invention can realize long-distance real-time high-efficiency transmission of coordinate data and draft data, real mapping and mapping data real-time summary, thereby greatly improving working efficiency from measuring to mapping.

Description

technical field [0001] The invention relates to the fields of surveying and mapping and communication, in particular to a digital surveying and mapping method. Background technique [0002] Ground digital mapping is a method of collecting digital topographic data in the field by using electronic total stations or other surveying instruments, and obtaining digital topographic maps through computer processing with the support of mapping software. At present, the digital mapping mode generally uses coordinate data collected in the field, and at the same time draws a topographic sketch on paper, returns to the room for wired data transmission, coordinates the points on the topographic map drawing software, and draws a topographic map according to the sketch. Recently, despite the emergence of short-range wireless communication technology represented by Bluetooth, it still cannot fundamentally solve the problem. If the above method is used to transmit the data measured by the to...

Problems solved by technology

Recently, despite the emergence of short-range wireless communication technology represented by Bluetooth, it still cannot solve the problem fundamentally.

If the above method is used to transmit the data measured by the total station to the computer in real time, the computer needs to be carried on site, and the computer and the total station are required to work together or at close range. Mapping, the time period for mapping is long, which affects the efficiency of mapping. If the survey area is large, the surveying and mapping data of each team cannot be summarized in real time, and the task cannot be completed under certain circumstances. At the same time, the work intensity of field personnel is high, and operators have to Inadequate rest, resulting in low productivity
