New features and enhancements

Simplified project-centric workflows

Trimble Access 2025.20 brings a simplified approach to managing projects and data by creating a more project-centric system. At the heart of this update is the ability to configure the Coordinate System, Units and Feature Library settings for projects. The new Project data page provides a convenient central location for managing all files shared across jobs within the project. This update makes project setup, job creation and design file management easier, promotes consistency, and improves the flow of data between the field, cloud, and office.

Configure job settings at the project level

You can now define the coordinate system, units, and Feature Library settings at the project level, making it easier to create new jobs from the project settings. You can define these settings for projects created in Trimble Connect and then downloaded to the controller, or for projects created in Trimble Access. By default, when you create a job the project settings are used to create the job. This ensures project-wide consistency and minimizes setup errors. If needed you can still create jobs from templates or from JobXML or DC files.

Project data management

There are a range of improvements have been made to help manage project data:

  • The New project workflow in Trimble Access now includes a step to easily add files to the project from Trimble Connect, a local folder or another location on the controller.

  • When you open a project, the project screen now shows the Jobs page listing the jobs in the project, and the new Project data page, where you can easily manage the design files available for use with jobs in the project. Tap Add to add files from Trimble Connect, a local folder or another location on the controller. Tap to hide files when you don't need them and to tidy up the project data list.

  • In the Layer manager, the Point files and Map files tabs are now consolidated into a single Project data tab. Use the Project data tab to select the project data files to use with the open job and to control whether data in the file is selectable.

  • Files tagged in Trimble Connect with TrimbleAccess.ProjectFile are now automatically downloaded to the controller for all users in a project, streamlining office-to-field workflows.

  • All files added to the Project data page from Trimble Connect are kept up to date so long as you are signed in to Trimble Access.

  • Local files on the Project data page can now be uploaded by tapping the upload icon giving you direct manual control to upload project files to the cloud when you're ready. This has replaced the Upload linked files setting.

  • Topographical surfaces created in Trimble Access (TTM files) are now uploaded to the cloud with the rest of the project and can be viewed in the Trimble Connect Field Data extension.

Job workflow improvements

We have improved the software behavior when updating job status and uploading job data to the cloud so that updates are more visible and intuitive:

  • Automated status updates

    The status of a job is now automatically set to In progress when you start a survey, and when the job is in a cloud project the job is automatically uploaded to the cloud so that it is visible in the Trimble Connect Field Data extension.

  • Interactive status control

    You can now change the status of a job (for example, to In progress or Fieldwork complete) by tapping the job status icon next to the job name in the Jobs page.

  • New Closed status

    Once the job status is set to Closed in the Trimble Connect Field Data extension, Trimble Access asks for permission to delete the job from the controller. This helps to free up storage space on your device.

Job filter improvements

We have simplified the filters available in the Jobs page and improved performance when filtering the list of jobs in a cloud project that has a large number of jobs. Select from the following filters:

  • Cloud jobs: All displays all jobs in the cloud.

  • Cloud jobs: Assigned to me displays only cloud jobs assigned to the signed in user.

  • Cloud jobs: Status closed displays all jobs in the cloud that have a status of Closed.

Enhanced GNSS tracking with GeoLock

We have added an enhanced target lock mode called GeoLock™, which is GNSS-assisted Autolock®. GeoLock replaces GPS Search and is available with all Autolock-enabled instruments. GeoLock significantly improves the instrument's active target tracking, boosting your productivity. Key features are:

  • Easier target reacquisition: The redesigned Target control settings page makes regaining lock to your target even easier, regardless of the environment you are working in.

  • Predictive tracking: When lock is lost, the instrument continues turning at a similar velocity, allowing Autolock to automatically snap back to your target. In situations when predictive tracking does not lock back onto the target, select a suitable automatic behavior:

    • Track GNSS: For integrated surveys using a receiver with excellent GNSS positions, the instrument turns directly to your location and locks on to the target. In many environments, this also works well with lower quality GNSS positions.

    • Search: GeoLock turns to your GNSS location and then automatically performs a search. Trimble Access monitors the position's precisions and only turns vertically when the vertical precisions are good.

    • Show video/joystick: The instrument turns to your GNSS location, then displays video and the joystick screen for finer control. This is useful in tough GNSS environments, such as when working among trees. You can also access the Search options directly from the Joystick screen. When lock is regained the Video/Joystick screen automatically closes.

Resection options for point usage

The new Usage group box in the Point details screen provides an easier way to manage points in the resection solution. The new Observation use field lets you decide whether the point is used in the calculation. Select from Let resection decide, Enabled, or Disabled.

User experience improvements

  • The Jobs tab now loads much faster and is more responsive for cloud projects that contain thousands of jobs.

  • Trimble Access is now much more responsive when working in cloud projects that contain thousands of jobs and Automatically upload the current project is enabled.

  • When adding project data to the Layer manager, the default location in the Trimble Access file browser is now always the last used location. In previous versions Trimble Connect was the default location whenever you were signed in.

  • To reduce clutter, the Scans and Inspections tabs in the Layer manager are now shown only when scans or inspections have been created in the job.

  • The software no longer restarts when you enable or disable Dark mode in the Map settings screen.

  • To optimize radio bandwidth, the video feed from a Trimble S Series total station is now paused when not being used.

Auto attributes in feature library files

Trimble Access 2025.20 adds support for auto attributes added to feature types in feature library files created using the Feature Definition Manager.

When measuring or working with features in jobs, auto attributes assigned to that feature type are automatically filled with data from the measured point or calculated data. Available auto attributes are:

  • Points: Northing, Easting, Height, Latitude, Longitude, Elevation

  • Lines: Length

  • Polygons: Perimeter, Area

These attributes are read-only in Trimble Access and Trimble Business Center. Values are recalculated if a point or feature is changed.

Use one code for points and lines

You can now use the same code for both point and line/polygon features.

For example, instead of using two codes for a pipe (PIPE_JNT for the point and PIPE_L for the linework), you can now use one code (PIPE) for both.

How it works:

  • In the feature library: Set up two codes with the same code name (for example, PIPE), one as a point feature (with its symbol and attributes), and the other as a line feature (with its line type and attributes).

  • In the field: When you use that code, you'll be prompted for the point features first, then the line features. The correct symbols and line types are applied automatically. This change means a simpler code library and faster, more intuitive field collection.

New Surface frame scan method

Trimble Access 2025.20 adds the new Surface framing method when scanning using an Trimble SX10 or SX12 scanning total station. This method allows you to select a surface from a design, such as a BIM model, and have the software compute a scan frame that covers that entire surface.

To define the frame area using a surface, you must select the surface in the map. In the Scanning screen select Surface as the framing method and then tap the Select surface softkey to use the surface you have selected in the map. If needed you can specify an Inflation factor to inflate the scan frame beyond the edges of the design surface.

Measure design elevation

You can now measure a design elevation directly from a physical point or reference, such as a line on a wall. This provides a precise and efficient alternative to manually typing the elevation, which is especially useful for building construction projects. This option is available when using a Total Station in DR and Prism mode or with a GNSS receiver.

Editing polylines and polygons from items in a linked file or background map

When editing a single polyline or polygon in a linked file or Web Feature Service, the selected polyline or polygon is now automatically copied into the job. In Trimble Access 2025.10 you always had to copy the polyline or polygon using the Create from selection option from the tap and hold menu before you could edit it.

The Create from selection option is still available for copying items into the job when you have selected multiple points, polylines, and polygons from a linked file or Web Feature Service in the map.

Enhanced linework creation

Trimble Access 2025.20 provides greater flexibility when creating feature coded linework using the Store polylines with codes on lines option.

  • Now you can create polylines and polygons with codes stored directly on the lines whenever you are using feature codes, including when using Measure points and Measure topo.

  • If you will use only existing points to create lines or polygons then you can use Measure codes without needing to connect to an instrument or GNSS receiver and start a survey. Select a survey style (which will not be used unless you measure a new point) and then start Measure codes. As long as you are using line or polygon codes you can select existing points to create linework. Trimble recommends disabling the Single tap to measure setting in the Measure code options screen so that you can more easily select multiple existing points.

This new Store polylines with codes on lines option was introduced in Trimble Access version 2025.10 for Measure codes, and allows for easier creation and modification of polylines and polygons using both existing and newly measured points. Points can be inserted effortlessly, making it ideal for workflows like cadastral surveys where points may be measured out of order.

For those who prefer the traditional approach, the Create feature coded linework with codes on points option is still available.

Both methods generate rich point symbols and linework defined in the FXL both in the field and in Trimble Business Center. You can configure your Feature code library to suit your preferred workflow using Trimble Access or the Feature Definition Manager.

Key benefits of Store polylines with codes on lines:

  • Flexible point order: Measure points in any order, then easily define lines.

  • Easy editing: Insert or remove points from polylines and polygons with ease.

  • Linework stored in the job: Polylines and polygons are stored directly in the job.

  • Streamlined cadastral workflows: Efficiently create parcel polygons.

Tips for Store polylines with codes on lines:

  • Tap New line to start a new polyline. The yellow highlight indicates the current polyline.

  • Tap the yellow linework to highlight it in blue for editing. Then tap a point and use Insert point or Remove point from the tap-and-hold menu.

  • Use Next or Prev to switch between polylines.

Dependent adjustments for Norwegian cadastral tolerance checking

When performing cadastral tolerance checking, Trimble Access calculates blunder detection as an independent adjustment, which meets current Norwegian cadastral regulations for GNSS measurements. In Trimble Access 2025.20 it is now possible to calculate a dependent adjustment if needed.

A dependent adjustment provides more flexibility where measurements or points are not fully independent and are linked to other measurements or to other established data points. To set the adjustment from independent to dependent, add independent="false" to the end of the Tolerances line in the CadastralTolerances.xml file.

For more information, see the topic Norwegian cadastral XML file setup in the Trimble Access Help.

New Bathylogger BL200 & BL700 echo sounder configuration file

The new Bathylogger BL200 ESD configuration file enables you to connect the Trimble Access software to Bathylogger BL200 and BL700 devices. For more information, go to bathylogger.com/support/.

This stylesheet is installed to the Trimble Data / System Files folder on the controller with the software. You can also download it from the Download configuration files page.

RTCM coordinate system messages

Trimble Access now supports reading the coordinate reference system (CRS) of the RTK base station from RTCM v3.4 type 1300 and 1302 messages if they are transmitted from the base. A warning message will be displayed if the global reference frame of the current job is not the same as the service CRS received in these RTCM message types. This feature is supported for controller internet connections only.

Scale ground coordinates from 0,0

When setting up a coordinate system for the project or job, the new Scale from field now appears in the Select coordinate system screen when you select one of the Ground options from the Coordinates field.

Use the Scale from field to select the point from which the job will be scaled:

  • Select the Project location option to scale everything in the job from the Project location. The Project location itself is not scaled.
  • Choose the Grid (0,0) option to scale everything in the job (including the Project location) from the 0,0 coordinate.

Resolved issues

  • Eject USB: If the software asked to "Eject USB device?", when you tapped Yes the software sometimes reported an error.

  • Export to top-level folder: You can now export to the top level folder of a drive, such as a USB drive.

  • Exporting to DXF: We have fixed the following issues:

    • Improved the positioning of text alongside points and lines when exporting to DXF, especially where the job uses International feet or US Survey feet.

    • When exporting from a job using a feature library file with the Store polylines with codes on lines option selected, the exported lines did not have the assigned color or layer from Trimble Access.

  • Exporting to NZ Fieldbook report (Word): We have resolved an issue with the reported GNSS receiver details when exporting to the NZ Fieldbook report format in Word. The updated stylesheet is available from the Download stylesheets page.

  • ESRI Shapefile export: We have fixed the following issues:

    • Extended menu attributes, which allow more than one attribute value to be selected, were missing from an exported Shapefile.

    • EUREF-DK15 (used in Denmark) is now associated with ETRS89 (EPSG code 4258) during Shapefile export.

  • Extended attributes for lines and polygons: We have fixed an issue where extended menu attribute data was not always correctly propagated along the line or polygon being measured.

  • Job repair wizard: We have removed the Skip copy option from the Job repair wizard. This change ensures that a copy is always taken of the job before beginning the repair.

  • Overwriting an existing IFC point: We have fixed an issue when creating a point from an existing point in an IFC file, where if you chose to overwrite the existing point, the existing point was deleted but the new point was not given the same name as the deleted point.

  • Missing IFC properties: Trimble Access now supports the display of integer, boolean and logical property type attributes in IFC files.

  • Taped distances: We have fixed the following issues:

    • If you selected two points in the map and then opened the Taped distances screen the Start elevation and End elevation could not be set.

    • The length between two existing points was not calculated if the Elevation for the points was not set.

  • Distance along alignment: We have fixed an issue where the Distance along Alignment delta was incorrectly displaying a station or chainage value. This delta has been updated to now correctly display a slope distance based on the job unit settings from the start of the alignment.

  • Elevation offset from alignment: We have improved an issue when keying in a point relative to a station and offset of an RXL alignment with vertical geometry, where you can now enter an elevation if you are offset from the alignment.

  • Continuous topo in GNSS survey: We have fixed an issue reported in Trimble Access 2025.10, where if you attempted to measure additional distance-based continuous topo measurements after enabling or disabling IMU tilt compensation during the GNSS survey the software did not allow the measurements to be stored.

  • Horizontal tilt offset: We have fixed an issue when measuring a horizontal tilt offset point where the software would occasionally store points before the system had all the required data, which resulted in points which had no coordinates. The software now waits for all details to be available before it will store these points.

  • NTRIP global reference frame: We have fixed an issue where Trimble Access sometimes warned "Global reference frame of NTRIP mount point differs from current job" when the global reference frame settings for the job and the mount point appeared to be the same.

  • SX point cloud color by elevation: We have fixed an issue where if the point cloud color mode was Color By Elevation but the minimum and maximum elevation fields were left blank then the elevation gradient was shown only in the map but not in the video feed from the SX instrument.

  • Instrument collimation report: We have resolved an issue where the Instrument collimation report was not correctly checking whether collimation values in the instrument had changed between instrument setups. This stylesheet is now installed to the Trimble Data / (missing or bad snippet) folder on the controller with the software. The updated stylesheet is also available from the Download stylesheets page.

  • WMS sample data: We have resolved an issue where the job containing WMS sample data reported the data was unavailable. The updated job and WMS data is now available from the Download sample datasets page.

  • Survey Basic: When calculating the inverse between two points without starting a survey, the software now calculates the azimuth. Previously the software calculated the azimuth only when in a survey.

  • Application errors: We have fixed several issues that caused occasional application errors when using or closing the software. In particular:

    • On an Android controller when connected to a device and the Trimble Access software was running in the background (as when copying data onto the controller using a USB cable for example).

    • After canceling or exiting a connection to an NTRIP caster or other internet RTK server while the connection was being made.

    • When performing a resection during an integrated survey.

    • When measuring rounds.

    • When scanning using a horizontal band, full dome or half dome frame.

    • When using control codes to join points where the feature code includes a timestamp attribute.
