Intelligent data acquisition and visualization technology of field geology based on mobile devices

There are many sources, complicated types and huge quantity of field geological data, but the low digitization degree of data acquisition method and poor efficiency lead to the bottleneck of field geological data acquisition by big data. Field geological data acquisition based on mobile smartphones, tablets and other mobile devices is a trend. This paper studies the intelligent acquisition technology of field geological big data based on mobile devices. This technology adopts the mobile device with Android system, uses such methods as sensor-assisted cataloging, speech recognition-assisted cataloging, customizable dictionary-assisted editing, interface customization and associated data auxiliary cataloging, to assist the field data fast and intelligent collection work. In the field, this technology also can use the collected data on the Android to directly draw the geological map, and make the data visual on-site. Using the field drilling data, the study tested functions of data collection and geological catalog drawing. The results show that the method proposed in this paper can improve the efficiency and quality of data collection, and can directly draw geological map in the field.
