Treating method for land investigation information data

Abstract

The land investigating data processing method is one solution for land investigating operation system. In field operation, the land utilizing state vector diagram, compressed remote sensing image diagram and linear programming diagram are led into PDA; GPS receiver is used to receive satellite data, the received data are software analyzed in PDA to extract information and the information after coordinate conversion and matching with original diagram is displayed on the PDA screen. By means of the special software in PDA, the GPS locating points, the points in the vector diagram, the points in the screen or distance joining points are selected to constituted into investigating graph. The land investigating information of the graph is registered, and the graphic and attribute information is maintained. Through indoor operations including introducing the field collected information, etc., the land utilizing data base may be updated.

Description

technical field [0001] The present invention is a land survey system solution that uses portable equipment to collect, record and display land survey information in the field, and processes the data collected in the field to update the original data in the office. It belongs to electronic information and its corresponding processing. The technical field of the method. Background technique [0002] The current status of land survey methods in the land management industry is: [0003] a. Field survey: Investigators take the paper-based land use status map and video map, go to the site to use tape measure, total station and other equipment to conduct surveying and mapping, and draw sketches by hand: [0004] b. In-house processing: In-house operators draw graphics on the original land use status map according to the data and sketch information in the field, and update the original maps or databases. [0005] The current problems with this approach are:...

AI Technical Summary

Problems solved by technology

[0006] a. 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;

[0007] b. Mainly manual work, which takes a long time, slow speed, many steps, complicated procedures and high labor intensity;

[0008] c. The information obtained from the on-site investigation needs to be manually plotted on the paper map, which is not convenient for field work, but also increases the process of indoor information processing, which is easy to cause human errors

[0009] d. Low work efficiency, high personnel investment, large capital investment, and long work cycle make it difficult to ensure high-quality data
