The technique of data input into the digital regional geological survey systems in the course of PRB preprocessing:An example from the 1:250000 Jangngaidarina Sheet

The present paper deals,in detail,with the technique of data input into the digital regional geological survey system in the course of PRB preprocessing,digitalization of various data and input into RGMAP system.Then these data will be built into multiple dimensions of productions and conformed to a unified space so as to make preparations for the following PRB processes of digital regional geological survey.
