  • Configurable processing interval and notifications
  • Can be run as a server process with minimal UI (ArcGIS Desktop license required for full functionality)
Trimble Positions Workflows

Trimble Positions Desktop supports a wide range of office-field-office data collection and maintenance workflows. Check out the sections below to learn how Trimble Positions provides an end-to-end solution for seamless integration of high accuracy GNSS data.

Trimble Positions with TerraFlex

Trimble Positions Desktop provides functionality for extending geodatabase schema and features into TerraFlex templates and forms.

  • Publish templates directly from layers in your GIS (including domains and subtypes) for new data collection
  • Define auto-collected fields for data to be automatically collected in the field forms
  • Setup metadata fields and accuracy requirements to track the quality of the data going into your GIS
  • Select existing features to send to TerraFlex (optionally as part of a task)
  • Download collected forms back into the GIS with filters for task, date, layer, extents, etc.
  • Supports real-time corrected workflows
  • Post-process the collected data for higher positional accuracy
  • Perform data QA/QC to review collected feature geometries and accuracies
  • Update geodatabase features with accurate geometries and metadata
  • Supports real-time corrected and post-processed workflows
  • Note: TerraFlex workflows without post-processing or feature QA/QC are also supported in the single-workflow TerraFlex Desktop add-in for ArcGIS Desktop.

 

Trimble Positions with TerraFlex Workflow

Trimble Positions with TerraFlex (Offline Data Transfer)

Trimble Positions Desktop also enables an offline data transfer workflow for TerraFlex through the use of a familiar check-in/check-out model of operation. The offline workflow also supports post-processing to achieve your accuracy goals.

  • Create templates directly from layers in your GIS (including domains and subtypes) for new data collection
  • Define auto-collected fields for data to be automatically collected in the field forms
  • Setup metadata fields and accuracy requirements to track the quality of the data going into your GIS
  • Check-out existing features, or just the templates, to a field database that can be copied to the TerraFlex field device using any file transfer mechanism
  • Check-in new and edited feature data from the field database (coped back to the desktop using any file transfer mechanism) back to the geodatabase
  • Postprocess the collected data for higher positional accuracy
  • Perform data QA/QC to review collected feature geometries and accuracies
  • Update geodatabase features with accurate geometries and metadata
  • Supports real-time corrected and postprocessed workflows

 

 

TerraFlex Workflow

Trimble Positions with TerraSync

Trimble Positions streamlines the process of getting field data collected with TerraSync back into your GIS. It all starts with Trimble Positions Desktop which enables you to set up and manage your TerraSync data collection projects.

  • Create TerraSync Data Dictionary Files (DDF) directly from the layers in your GIS (including domains and subtypes) for new data collection
  • Check-out existing features to SSF files for updating in TerraSync
  • Setup metadata fields and accuracy requirements to track the quality of the data going into your GIS
  • Check-in SSF files from the field
  • Post-process the collected data for higher positional accuracy
  • Perform data QA/QC to review collected feature geometries and accuracies
  • Collected features and their metadata will be stored straight into the GIS
  • Supports real-time corrected and post-processed workflows

 

Trimble Positions with TerraSync Workflow

Latest Releases

v10.8.0.1

  • Local postprocessing for the TerraFlex cloud workflow. During publishing, projects can now be configured for postprocessing. Data collected through TerraFlex on an Android™ device or Windows® device with supported Trimble receivers (R1 or R2 GNSS receiver, TDC150 GNSS handheld receiver, EM100 GNSS module) can be downloaded and postprocessed in the Desktop add-in using the existing Session Manager workflow.
  • Support for ArcGIS Desktop 10.8. The Desktop add-in now supports ArcGIS Desktop 10.8 and should support future point releases without requiring an updated installer. Additionally, compatibility with ArcGIS Desktop 10.2.x and 10.3.x has been restored.
  • Software auto updater. The Desktop add-in now notifies you that a newer version is available. Using the Desktop Configuration app, minor updates can be downloaded and installed on-the-fly while major updates can be downloaded and installed manually.
  • Create and include background map packages with TerraFlex Offline projects. Users of the TerraFlex Offline workflow can now generate and include custom basemap and reference layer packages in the .tfin file sent to TerraFlex.
  • Accuracy reporting (68/95%) option for TerraFlex workflows. Users of all TerraFlex workflows can now configure accuracy reporting for both field and office. Additional office-side metadata is also available.
  • TerraFlex Offline files can be checked in from, and out to, a connected MTP (USB for file transfer) device. If an Android device is connected to a Windows device over USB in MTP mode, you may be able to work with it directly from the check-out and check-in functionality in the TerraFlex offline workflow. This could improve data transfer Trimble Positions Desktop Add-in Release Notes | 3 workflow functionality with a subset of devices. Note: Only one connected device is supported (e.g., you can’t have an external hard disk connected at the same time).
  • New office-side metadata fields. Based on customer requests, several new metadata values have been added that can be transferred to feature class attributes when forms are downloaded: Accuracy Reporting Setting, X Coordinate (in the current map coordinate system), Y Coordinate (in the current map coordinate system).
  • Improvements to TerraSync SSF/DDF import workflows. DDFs with an older schema version (v5) can now be used. In addition, a coordinate system can be selected for the created file geodatabase when importing a DDF/SSF. Finally, you can choose whether to propagate the required field property from the DDF into the feature class attributes.
  • Steps to improve CBS list download. As Trimble moves towards distributing additional, region-specific CBS lists, improvements have been made to the Manage base stations area of the Desktop Configuration app. The existing CBS list is now called the "Classic CBS List" and you can see information about when it was last updated, how many stations it contains, and the reference frame, prior to download. It is through here that you will eventually see new, region-specific CBS lists in different reference frames.
  • Improvements to the session context (right-click) menu. When right-clicking on a session in the session list, you will see an expanded list of options. You now have explicit control over how the feature geometries are rebuilt in the session: Rebuild with best results, Rebuild with last results. Additional information is also displayed in the Properties window.

 

v10.7.1.1

  • Support for ArcGIS Desktop 10.7 and 10.7.1. The installer now properly supports ArcGIS Desktop 10.7 and 10.7.1. 
  • Support for TerraFlex with Offline Data Transfer and Postprocessing workflows. The add-in now supports an offline workflow for TerraFlex whereby projects can be created through the add-in and data can be checked-out for manual file transfer to TerraFlex. Returning data can be checked in and postprocessed with QA/QC for supported receiver configurations. Local field configurations can also be included in a project. 
  • Easier configuration for common metadata and auto-fill fields. Improvements have been made to the Layer Settings page of the project wizard to make metadata field configuration easier. You now have the option to ‘add all (common)’ fields in a single click. 
  • Accuracy reporting setting now visible everywhere accuracies are reported. In the dockable window, feature and position accuracies have always been reported in the configured accuracy reporting setting (“68% RMS” or “95% 2DRMS”). This is now labeled in the table column headers and is also made available as transferrable metadata. 
  • Improved real-time correction datum configuration. Previously, the field configuration wizard always used an Esri coordinate system selection tool for setting the coordinate system of the real-time correction source. This made sense for Esri field workflows but did not make sense for Trimble field workflows that utilize the Trimble Coordinate System Database (CSD). Field configurations created as part of the project wizard for TerraFlex Offline and TerraFlex on Connect workflows will now use a Trimble coordinate system selection user experience.

v10.6.0.1

  • The Trimble Positions Desktop add-in now supports ArcGIS Desktop 10.5.1, 10.6, and 10.6.1.
  • There are other improvements in the area of additional metadata support (for TerraSync workflows) and bug fixes for elevation (Z coordinate) handling. Please refer to the release notes for additional information.
  • TerraSync SSF files with attribute-only edits can now be checked in using Trimble Positions Desktop add-in.
  • Trimble Positions Desktop Configuration Utility now allows users to manage the default folders used by the Data Transfer utility.
  • The name of a string field can now be specified for the storage of a single photo URL for TerraFlex forms (e.g., to allow for use with ArcGIS Desktop Basic).

v10.5.0.2

  • Create waypoint files: You can generate waypoint files for TerraSync from features in your GIS.
  • Create SSF background files: You can generate SSF background files for TerraSync from layers in your GIS.
  • Support for multiple images per feature: You can set up multiple image fields per feature in their TerraSync DDF, and all captured images will be stored using Attachments in the GIS.
