Differential corrections to improve the quality of GNSS data collected in the field Postprocessing with Trimble GPS Pathfinder Office software significantly improves the autonomous accuracy of data collected in the field all the way down to centimeter (1 cm / 0.4 inch) level, depending on the environment and the GNSS receiver.
GPS Pathfinder Office software also includes the unique Integrity Index grading system, which ensures that GNSS field data is differentially corrected using the best quality base station data available.
H-Star data processing for high accuracy and support for GLONASS postprocessing Trimble GPS Pathfinder Office software supports the complete Trimble Mapping and GIS GNSS portfolio, as well as associated positioning technologies, such as Trimble H-Star™.
Data import and export in a variety of GIS and CAD formats Data can be imported to Trimble GPS Pathfinder Office software from a number of GIS and database formats, allowing previously collected GIS data to be taken back to the field for verification and update. The software's Data Dictionary Editor creates custom lists of features and attributes for field data collection and supports the development of conditional attribute data capture forms in Trimble TerraSync™ software that dynamically adapt to previously entered attribute values for maximum data collection efficiency.
Sophisticated data dictionary editor to ensure consistency between the field and the office By creating a data dictionary or importing one from a GIS based on its exact data schema, GIS administrators can be confident that data collected in the field will integrate seamlessly with the GIS repository and that data returned will be accurate and consistent. In the field, the data capture form prompts field workers to enter specific information, ensuring data integrity and compatibility with the GIS.
Trimble TerraSync Studio utility within GPS Pathfinder Office software is used to develop and test customized TerraSync user interfaces. To improve the field worker experience, the TerraSync user interface can be simplified with this utility, removing functionality to ensure maximum field productivity and eliminate potential configuration errors. Waypoint files can also be created in the software to assist with navigation and efficient asset relocation.
Quality control of GNSS data before exporting to GIS Trimble GPS Pathfinder Office software includes quality control features critical for enterprise GIS data development. For example, collected features can be compared against any number of background datasets such as vector GIS data, aerial photographs or satellite imagery in order to verify accuracy and detect conflicts. Background data can be imported to GPS Pathfinder Office software from GIS systems, directly from imagery files, or referenced directly from a web map server.
In addition, before transferring collected features to a GIS, CAD, or database system, they can be analyzed to confirm they are complete and free of errors. Positions and attributes can be changed and unnecessary or unwanted GNSS positions can be deleted with GPS Pathfinder Office software to ensure that only the highest quality data is exported to the GIS.
