Geological navigation and geological surveying and mapping methods for portable smart devices based on andriod

Abstract

The invention relates to a geological navigation and surveying and mapping working method using an Android tablet or a mobile phone, and belongs to the technical field of geological survey. The method of the present invention is based on the Andriod operating system, which consumes less memory than the Windows operating system software, and the equipment is convenient to carry, has many user groups, and the equipment price is relatively low and easy to popularize; utilizing GIS+GPS integration technology, field navigation and positioning are more efficient after coordinate processing Accurate; establish a dynamic and updateable two-dimensional or three-dimensional geological information GIS database. The geological record information includes audio and video information. The field operation is intuitive and simple, the content level is clear, and there is no repetition or omission. The recording method improves the efficiency of field work, and through synchronous communication with rear experts, it fills the gap in the systematic quality control procedures of field engineering geological surveying and mapping, and can also adjust the work plan in time, making the field geological surveying and mapping goals clearer.

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 field engineering geological surveying and mapping method is completed by paper medium + manual collection, which makes it difficult to carry and manage background data, written records, sketch maps, catalogue maps, geological photos and sampling information, narrow the survey field of view, and take time to find geological targets. laborious. The positioning accuracy of geological feature points, lines, surfaces and volumes is greatly affected by terrain accuracy and experience. There is almost no synchronization between on-site geological mapping and the rear, and quality control is difficult.

Problems solved by technology

[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.
