Problems solved by technology

[0004] a. It is necessary to prepare and carry a variety of paper maps, which brings a lot of inconvenience to field operations;
[0005] b. Absolute positioning is not possible. When measuring the inflection point of ground features, a reference object is required, and field personnel are required to have good measurement expertise;
[0006] c. Mainly manual work, which takes a long time, slow speed, many steps, complicated procedures and high labor intensity

Abstract

This invention relates to a full-digitized field information acquisition, recording and processing method for land survey. Wherein, it uses field portable device integrated all of space geometrical data real-time high-precision acquisition, field forming image, attribution information field record, data measurement and graphic edition, as well as the wireless network communication, serial port / blue tooth communication, space geographic coordinate conversion, and different graph data composition. This invention realizes WYSIWYG, decreases labor strength, and improves operating efficiency with paper free, real time, and intelligentization.

Description

technical field [0001] The present invention is a method for real-time and high-precision collection of spatial geometric data, on-site mapping, on-site input of attribute information, data measurement and graphic editing in land survey using portable equipment in the field, and belongs to land management electronic information collection and corresponding processing methods technical field. Background technique [0002] The current method of conducting field surveys in the land management industry is: investigators take paper land use status maps and image maps, go to the site to use tape measure, total station and other equipment, measure on site, and draw sketches by hand. The specific technical means to obtain the changed data mainly include simple supplementary measurement method (such as intercept method, distance intersection method, rectangular coordinate method, extension line intercept method), flat panel supplementary measurement method (polar coordinate method, f...
