RTK GPS Utility Mapping Services in Minneapolis, MN

Paint and flags answer one question: what’s safe to dig today. They don’t answer the question that comes up again in two years when a different crew is back on the same property. All Clear Locating Services provides RTK GPS utility mapping throughout Minneapolis and the Twin Cities metro, turning every locate into a permanent, survey-grade digital record instead of a mark that washes away with the next rain.

RTK, or Real-Time Kinematic, GPS corrects a standard satellite position against a fixed reference signal in real time. The result is horizontal accuracy within about an inch on every point our technicians capture — precise enough to drop directly into CAD drawings, GIS layers, and as-built documentation, not just a field sketch.

Whether you need documented private utility locating for an insurance file, GPS-verified records ahead of a commercial permit review, or full underground utility locating tied to survey-grade coordinates, our RTK GPS utility mapping service in Minneapolis, MN gives you data that holds up long after the paint fades.

What Is RTK GPS Utility Mapping?

RTK GPS utility mapping is the process of locating buried utility lines and then capturing their exact position with survey-grade GPS equipment, rather than relying on flags and paint alone. Every point — a bend in a gas line, a splice in a fiber run, the corner of a septic tank — is logged with coordinates you can reuse.

We map:

Private electrical, gas, and propane lines
Water, irrigation, and septic infrastructure
Communication and fiber optic cable
Storm drainage and unknown underground structures
Public/private utility crossings on larger sites

The output isn’t just a marked yard. It’s a dataset:

Exportable point and line data (KML, shapefile, or CAD-ready formats)
A PDF site map showing every located utility relative to structures and property lines
A permanent digital record tied to the property, not to memory

Why RTK GPS Accuracy Matters

A phone’s GPS is accurate to roughly 10–16 feet — close enough to find a street, not close enough to avoid a gas line. RTK GPS closes that gap.

Standard Locate Marking

Paint and flags mark the surface only
Marks fade, get mowed over, or wash away within weeks
No record survives past the current dig
Difficult to share with engineers or future contractors

RTK GPS Documented Locate

±1″ horizontal accuracy on every located point
Digital record you keep indefinitely
Data exports directly into GIS and CAD workflows
Supports permit applications, as-built drawings, and future project planning

Our RTK GPS Mapping Process

Step 1 — Locate & Detection

We start with the same electromagnetic and GPR detection used in our underground utility locating and private utility locating services, tracing every line on the property before anything is logged.

Step 2 — RTK GPS Data Capture

Once a line is confirmed, our technicians capture its position with RTK GPS equipment, logging depth where determinable and recording each point against a fixed correction source for survey-grade accuracy.

Step 3 — Mapping, Export & Delivery

Data is compiled into a site map and exported in the format your project needs — a PDF for a permit file, a shapefile for a GIS department, or CAD-ready coordinates for an engineer.

FAQS

Is RTK GPS mapping different from a standard utility locate?

Yes. A standard locate marks utilities on the surface with paint and flags. RTK GPS mapping adds a permanent, survey-grade digital record of those same utilities that you keep after the marks are gone.

Do I need GPS mapping if I only need a quick locate?

Not necessarily. For a one-time residential dig, a standard private utility locate is often enough. GPS mapping is worth it when you need documentation for permits, future work, or a larger site.

What file formats do you provide?

We can deliver a PDF site map, KML or shapefile data, and CAD-compatible coordinates depending on what your engineer, GIS department, or permit office requires.

How accurate is RTK GPS compared to a phone or handheld GPS?

RTK GPS is accurate to roughly one inch, compared to 10–16 feet for a standard phone or consumer GPS unit — a difference that matters when a utility line is involved.

Can RTK GPS mapping be combined with a locate on the same visit?

Yes. In most cases we locate and map in a single site visit, so you get marked utilities and a documented record without scheduling two separate appointments.
