Features
Everything you need at the roadside
Replace paper strip maps, estimates and "what km are we at?" phone calls with one app for locating, recording and sharing positions on the Queensland Main Roads network. It runs in any browser, on any phone or tablet, and installs like a native app.
Find the chainage
Know exactly where you are
Accurate chainages from a tap, your GPS or a search.
Live GPS tracking
Turn on tracking and the chainage updates as you travel along the corridor — ideal for a passenger recording chainages during a site inspection.
Flexible search
Go straight to a road name, or a section and chainage, enter a latitude and longitude, or paste a Google Maps link from an email or message.
Map views
The right view for every task
Map layers and imagery for planning and site work, day or night.
Main Roads overlay
The state-controlled network is drawn over the map so you always know which roads are Main Roads. Switch between day and night maps, Google Maps and satellite.
Full-screen Street View
Open Street View full screen with a heading compass and distance display to check signs, lanes and sight lines before you mobilise to site.
Smart dropped pins
Pins snap to a Main Road only when you tap directly on it. Otherwise they stay where you placed them, with a dotted line to the nearest chainage and a one-tap option to snap to the road.
Projects & hub
Keep every job in one place
Sign in to save, organise and document your work.
Points, pins & ranges
Save chainage points, dropped pins and chainage ranges — a line that follows the road from, say, 0.5 km to 3.2 km. Organise them into phases with their own layers, plus base layers that always show.
Markers, labels & photos
Choose from 16 marker shapes and any colour, turn on always-on map labels, move or re-chainage saved points, and add notes, links and photos taken on your camera or uploaded.
A hub for every project
Details, files, an activity log and access control for each job — filed in your own folders, with searchable tags and a "Shared with me" view.
Sharing & teams
Bring your whole team
Share exactly what people need to see — nothing more.
Controlled share links
Create multiple links per project, each scoped to the phases and layers you choose. Add a password, set an expiry, control photo viewing and downloads — and revoke any link at any time.
Viewers are free
Invite clients, inspectors and subcontractors as viewers at no cost. Anyone viewing a share link or a project shared with them never needs a paid seat.
Teams & roles
Create a company, invite members and assign roles with fine-grained permissions and pooled storage. One person can belong to several companies.
Road data
Traffic and route data
Volumes, speeds and heavy-vehicle access for the location you select.
Traffic volumes
See AADT (annual average daily traffic) with its volume category and heavy-vehicle percentage, plus TMR speed signs along the road.
AADTHV %Speed signs
Speed limits & HV routes
Tap "More information" for posted speed limits from OpenStreetMap and NHVR heavy-vehicle route access at that location.
Export your data
Take project data anywhere as GeoJSON or CSV — ready for your GIS tools, spreadsheets and reporting.
Project hub
A central record for every job
Every project map is backed by a hub for its documents, people and history, so your team always has the current TGS without searching through email.
- Notes & details — client, job or reference number, status and dates.
- Project files — PDFs, drawings, spreadsheets and TGS/TMP documents alongside the map.
- Activity log — who added, edited or moved what, and when.
- Folders & tags — your own structure, like Traffic Guidance Schemes › Client › Project, plus searchable tags and "Shared with me".
- Access control — decide exactly who can see and change each project.

How it works
From roadside to shared plan in four steps
-
STEP 01
Tap or search
Tap the map, use your GPS, or search by road and chainage, coordinates or a Google Maps link.
-
STEP 02
Get the chainage
Instantly see the km, road, section, carriageway and distance to road — plus traffic data for that spot.
-
STEP 03
Save to a project
Keep it as a point, pin or range, with the right marker, notes and photos, in the right phase.
-
STEP 04
Share with your team
Send a share link limited to the phases and layers people need, or invite your team and viewers, so everyone works from the same map.
Companies & teams
Run your whole company on one map
Create a company workspace, invite your people and give each of them exactly the access they need. Company projects belong to the company — so when someone moves on, the work stays.
- Seats for your team — the company owner pays for member seats. Viewers never need one.
- Roles that fit — Owner, Admin, Accounts, Project manager, Editor, Contributor and Viewer, plus custom roles.
- Fine-grained permissions — control who can create or delete projects, manage share links, create unprotected links, manage billing or export.
- Pooled storage — every seat adds to one shared company allowance.
- Many companies, one login — work across several companies without juggling accounts.
