Method for geological navigation and geological mapping through portable intelligent device based on Andriod

Abstract

The invention relates to a method for geological navigation and mapping by using an Andriod flat panel or a mobile phone and belongs to the technical field of geological survey. The method is based on an Andriod operating system and consumes a less memory, the device is convenient to carry, user groups are many, and the device is low in price and easy to popularize; a GIS+GPS integration technology is utilized, and the field navigation and positioning is more accurate after coordinate processing; a two-dimensional or three-dimensional geological information GIS database that can be updated dynamically is established, geological recording information comprises audio and video information, the field operation is visual and simple, the content level is clear, no repetition or omission occurs, a previous pure recording mode of character and photo information is changed, the field working efficiency is improved, the blank of field engineering geological mapping system quality control procedures is filled through synchronous communication with rear experts, a working plan can be adjusted timely, and field geological mapping target is clearer.

Description

technical field [0001] The invention belongs to the technical field of geological survey, and in particular relates to a geological navigation and surveying and mapping working method using an android tablet or a mobile phone. Background technique [0002] The traditional method of field engineering geological surveying and mapping is completed by paper media + manual collection, which makes it difficult to carry and manage background data, text records, sketch maps, catalog maps, geological photos and sampling information, narrow survey field of view, and time-consuming to find geological targets strenuous. The positioning accuracy of geological feature points, lines, planes, and volumes is greatly affected by terrain accuracy and experience. On-site geological surveying and mapping have almost no synchronous communication with the rear, and quality control is difficult. To a certain extent, it is difficult to adapt to the increasingly severe market competition situation. ...

[0002] The traditional method of field engineering geological surveying and mapping is completed by paper media + manual collection, which makes it difficult to carry and manage background data, text records, sketch maps, catalog maps, geological photos and sampling information, narrow survey field of view, and time-consuming to find geological targets strenuous

The positioning accuracy of geological feature points, lines, surfaces, and volumes is greatly affected by terrain accuracy and experience. On-site geological surveying and mapping have almost no synchronous communication with the rear, and quality control is difficult. To a certain extent, it has been difficult to adapt to the increasingly severe market competition situation

At present, there are some field geological data acquisition systems based on notebook computers, professional GPS, 3G mobile phones and tablet computers under Windows operating system, but there are many deficiencies in varying degrees, such as single function, no integration of multiple sensors, no database integration, data The management level is not clear, and it is prone to repetition and omission; the acquisition system software based on the Windows system consumes a lot of memory and power, has a short standby time, and has a large equipment size. It is not conducive to popularization and use; traditional maps are used for geographic navigation, and design objects, geological maps, and seismic zoning maps cannot be used as background navigation functions. Geological information records mostly rely on traditional text + photo forms, and work efficiency is low; the coordinate information recorded on site is longitude and latitude. It cannot directly reflect the actual distance information; the data cannot be synchronized to the rear database, and the quality of work cannot be controlled, etc.
