Frustrations E X P E R I E N C E Y O U R A M E R I C A 12Fractious GPS environment on multiple levels. Individualistic nature of the Park ServiceHighly varied budgets for equipment/software Contracting’s role in purchasingIncredibly fast pace of changeImpacts support…Affects consistency of data collection
Future E X P E R I E N C E Y O U R A M E R I C A 13Trimble….. Migration from PFO to Business CenterMigration from TerraSync to TerraFlexEnterprise License Agreement ESRIGrowing interest in Collector…High Accuracy versionArcPad is being phased out…still well regarded
Future E X P E R I E N C E Y O U R A M E R I C A 14 Distinction between recreational, mapping and survey grade GPS will continue to blur….Fundamentals of space-based navigation still applySatellites still are in same MEO orbitsMultipath & SNR are still an issueExternal antennas still provide best resultsPosition averaging still key to minimize errorsCorrecting against a base station shifts your data!CORS - NAD83 (2011)
Future E X P E R I E N C E Y O U R A M E R I C A 15 NGS Replacing both NAD 83 and NAVD 88 in 2022http://geodesy.noaa.gov/datums/newdatums/index.shtmlWhy: Terrestrial vs Space-based survey methodsCrustal plate movement produces driftDynamic NSRS…daily datum adjustments?How to prepare:Good documentation…metadataFeature level metadata including date field

Future E X P E R I E N C E Y O U R A M E R I C A 18 NPS plans to work closely with NGS on the changeNPS advising against a dynamic daily datumRequesting 5-year epochs as reasonable alternativeGRD2022 (2025, 2030, 2035…)Update survey marker data sheets…more readable
