Control points and location knowledge

Control Point Management for Survey Companies

Most survey companies lose more time to finding marks and re-establishing points than to any office process. PLN stores that knowledge for the whole organization instead of in one surveyor's notebook.

Global control points screen with a searchable point list, coordinates, and a map of all organization control points
The last thirty metres are the hard part. Coordinates get a crew to the street. A photo, a note from whoever set the point, and a live camera bearing get them to the mark.

Stored once, reusable forever

Points are created from the field or the office and stay available to the whole organization instead of being re-established on the next job nearby.

  • Benchmarks and GNSS reference points
  • Temporary nails and site marks
  • Available to every surveyor in the company

Search, coordinates, and notes

Find a point by name, read its exact coordinates, and check the note that explains how it was set and whether it can still be trusted.

  • Searchable register
  • Exact coordinates
  • Condition notes from the surveyor who set it

Task areas on the same map

Task areas are shown next to the control point layer, so crews can see which points actually serve the job they are heading to.

  • Task geometry and point layers together
  • Nearby points surfaced in the field
  • Navigation handed to the phone

In the field

Open a point, see the picture, start navigating.

Each point opens with the note left by the surveyor who established it, the photo taken at the time, and a navigation action that hands the coordinates to the phone. No more calling the office to ask where the benchmark was.

Point detail

The note and the photo travel with the point.

A point set two years ago is still usable by whoever is nearest today, because the context that made it usable was stored with it rather than remembered by one person.

  • Photograph taken when the point was established
  • Condition note explaining how it was set
  • Coordinates ready to hand to a device

Camera guide

Bearing, remaining distance, and accuracy on the walk in.

The camera guide shows a live view with the direction to the mark, how far is left, and the current position accuracy, for the stretch where coordinates alone stop helping.

  • Live camera view with bearing to the point
  • Remaining distance as the crew walks in
  • Current position accuracy shown continuously

Task geometry

The shape of the job is part of the job.

A task is not only an address. When it is created it can carry a point, a line, or a polygon — the mark to set, the traverse to run, the parcel to pick up — and that geometry stays on the task for whoever picks it up.

Task places

Every open task on one map.

Crews see what is around them rather than what is on a list. Tasks near the current position are flagged, and the map shows the extent of the work rather than a single dropped pin.

  • Point, line, or polygon drafted on the task
  • Open tasks shown as places on the map
  • Nearby tasks flagged against the current position

Getting there

Hand it to the phone, then walk it in.

For the drive, the coordinates go to Waze or Google Maps like any other destination. For the last stretch, where a road app stops being useful, the camera guide — an augmented-reality view through the phone camera — shows the bearing, the distance left, and the current position accuracy. Control points live on the same map and are found the same way, with their note, photograph, and coordinates readable from the point itself.

  • Coordinates handed to Waze or Google Maps
  • Camera guide for the final approach on foot
  • Control points and task geometry on one map

Questions

Common buying questions.

Can a task carry a shape rather than just an address?

Yes. A task can be drafted with a point, a line, or a polygon when it is created, and that geometry travels with the task. Crews see open tasks as places on a map, and the coordinates can be handed to Waze or Google Maps for the drive, or followed with the camera guide for the last stretch on foot.

What kinds of points can be stored?

Benchmarks, GNSS reference points, temporary nails, and any other mark the company establishes. Each keeps its coordinates, a condition note, and a photograph.

Can field crews add points, or only the office?

Both. Points can be created from the mobile app while standing at the mark or from the office, and either way they become available to the whole organization immediately.

What is the camera guide for?

The final approach. Coordinates bring a crew to the right street; the camera guide shows bearing, remaining distance, and position accuracy for the last stretch on foot.
