Research And Programming On Quality Evaluating Of Geodetic Field Survey Produciton

Quality evaluation of geodetic field survey production include various product forms, such asobservation and monumentation product of GNSS, triangulation, traverses, leveling, gravity,astronomy etc. It need to check many observation documents, many items and many data files,what’s more, during this process it requires different quality elements to be referenced andevaluated, which amounts to a hard work. In the long run, quality evaluation of field surveyproduction is completed by manpower, in which way quality evaluation is not only inefficientbut also subject to man-made factors. In this context, this paper aims to modernization of qualityevaluation of field survey production. Concerning the problems such as the design of qualityevaluation process, detailing checking, initiazation of power value of quality element,construction of database of quality element, quality evaluation system construction is researched.Moreover, the software of quality evaluation of geodetic field survey production is developed,which basically realizes atomization of quality evaluation of field survey production.The research topics are as follows:1. On basis of analysis of current check standards and specification, it re-writes product checkspecification according to time sequence and classifies product as monumentation andobservation product. It combines check requirements with fault and leak types, and balancesbetween mathematical precision index and book leak and set their power.2. The grade standard of quality evaluation and database of quality grade are establishedaccording to specification.3. The software of quality evaluation of geodetic field survey production is developed, whichrealizes functions including quality check, quality evaluation of field survey product, andcreation of evaluation report.4.On basis of product database and database of quality element, the software realize manyanalysis function, such of leveling stadia analysis, quality element index computation of mp1,mp2of GNSS observation, observation environment variation of GNSS site, which can provideproof for quality valuation.
