The Design And Realization Of One-shot-Job System For Surveying

With the development of economy , the application of foserved value in many trades need surveying to collect data automatically , eve(?) more , to manage data intelligentizedly and distribute Real-time data on Internet . Today , the great progress in computer .special technology and infornation industry make surveying to achieve above-mentioned aim possibly .What we must do is only to cite the advanced equipments to surveying and explore their function to service surveying .The Personal Digital Assistant (PDA )is such advanced equipment .There is just several years and a decade since PDA appearing .But PDA has already been perfect not only in hardware but also in software .At the present time , PDA is used in surveying more and more widely . It has been a good helper for surveyor .At the base of investigation on many surveying units and analysis of a lot of existing software about surveying and mapping .this paper designs and develops an almost almighty system used on PDA for commonly engineering surveying .The author summarizes a suit of normative pattern work for field surveying such as differential leveling .traverse neasurement .control surveying ,cross-sectional surveying .lofting .exploration and fragment measurement. The paper realizes the measurement value circulating automatically from input to output .management and analysis .It discusses the system to do outdoor surveying work and indoor surveying work together .So it is good to enhance the surveyor's work efficiency .What is more ,it provide a stability foundation for observed value's application and issuance .
