GPSPPK技术在大比例尺地形图测绘中的应用 GPSPPK(Post-ProcessedKinematic)technologyiswidelyusedinlarge-scaletopographicmapping.ThistechnologycombinestheadvantagesofGPSpositioningandsurveyingmethods,providingaccurateandreliablemeasurementsforgeneratinghigh-qualitytopographicmaps.Inthisarticle,wewillexploretheapplicationofGPSPPKtechnologyinlarge-scaletopographicmapping,discussingitsbenefits,challenges,andpotentialfuturedevelopments. Introduction: Topographicmappingplaysacrucialroleinvariousfields,includingurbanplanning,infrastructuredevelopment,landmanagement,andenvironmentalstudies.Accurateandup-to-datetopographicmapsarenecessaryfordecision-makingprocesses,ensuringtheefficientutilizationofresourcesandtheeffectiveimplementationofprojects.Withtherapidadvancementoftechnology,GPSPPKhasemergedasapowerfultoolinlarge-scaletopographicmapping,offeringprecisemeasurementsandreducingthetimerequiredfordatacollection.
