·         ALWAYS include the epoch of each datum in your metadata

·         Use only CORS base stations for differential correction of GPS data

·         Manually seed NGS NAD83(2011) values in Pathfinder Office differential correction

·         Avoid applying transformations within Trimble Pathfinder Office

·         Assign .prj file to ensure the correct transformation(s) is applied in ESRI ArcGIS
