GIS & GNSS Mapping
Paint washes off. Flags get pulled. A geo-referenced digital record doesn't. Using a high-accuracy GNSS receiver with RTK correction capability, every located utility can be captured as a permanent digital feature and delivered in the format your workflow requires — from a Google Earth file a property owner can pull up on their phone to a Shapefile ready to drop into ArcGIS or Civil 3D.
Sample Reports
Our sample reports offer a clear and detailed overview of a professional home inspection, designed to help you understand the inspection process and make informed decisions.
Accuracy You Can Document. Deliverables You Can Use.
Locate data is only as useful as long as you can find it. We offer GNSS-assisted utility mapping as an add-on to any locate or as a standalone service for sites that need documented utility positions without a full locate mobilization. Using a high-accuracy GNSS receiver with RTK correction capability, located utilities are captured as geo-referenced digital features and delivered in the format your workflow requires.
RTK correction provides horizontal accuracy down to 1–3 cm where satellite geometry and site conditions allow — making this the highest level of field-captured utility positioning available outside of licensed survey work. Where RTK is unavailable due to canopy, obstructions, or satellite geometry, sub-meter accuracy is the standard baseline. Accuracy is logged per feature on every job so you always know exactly what the data reflects.
This is not a licensed survey. For projects requiring licensed survey deliverables, we recommend engaging a registered land surveyor.
Every locate we perform can include GNSS mapping at the time of service — one mobilization, two deliverables. While we're already on site locating and marking, we capture each utility as a geo-referenced digital feature. You walk away with your physical markings and a permanent digital record of everything we found.
This is the most cost-effective way to build a documented utility record for your property or project. No second mobilization, no scheduling a separate visit — just an additional deliverable added to work already being done.
Available for any locate service: sewer lateral, electromagnetic, GPR, gas line, electrical subfeed, or conduit investigation.
Already have utilities marked or documented on site and just need the coordinates captured? We offer standalone GNSS mapping visits independent of a locate service. We walk your marked utilities, capture each feature with position, depth where known, photos, and attributes — and deliver a geo-referenced file ready for your GIS, your project records, or your permit submittal.
Useful after a recent 811 locate, after your own crew has marked a site, or any time you need existing field markings converted into a permanent digital record before they wash off or get pulled.
Need documented utility positions for a job file, a project manager, or an owner deliverable? We provide a PDF map report alongside your choice of digital export — something you can hand up the chain or drop in the project folder without explanation.
Where the project timeline allows, GNSS mapping adds minimal time to a locate visit and gives you a record that holds up long after the paint is gone. If your project requires utility documentation for permitting, pre-construction planning, or excavation clearance — this is the add-on that makes your locate a complete deliverable.
COI available upon request. Same-day and next-day scheduling available when your timeline is tight.
Data delivered in your preferred format — Shapefile, DXF, KML, or CSV with PNEZD coordinates. Coordinate reference system configurable to your project: state plane, UTM, WGS84, or NAD83. Attribute schemas can be discussed in advance to match your existing data dictionary so imports are clean.
RTK correction capability brings horizontal accuracy to 1–3 cm where site conditions allow — the highest level of field-captured utility positioning available outside of licensed survey work. Every feature is delivered with its logged accuracy estimate so your team knows exactly what the data reflects before it goes into the model.
Useful for pre-construction conflict investigation, utility asset management, existing conditions documentation, and any project where field-captured utility coordinates need to integrate directly into ArcGIS, QGIS, Civil 3D, or a municipal GIS platform.
If you install it underground, you should document it before backfill. Fiber, irrigation, conduit sleeves, pool plumbing, sewer laterals, electrical subfeeds — once it's buried it's gone from sight and often gone from record. A GNSS mapping pass before you cover it takes minutes and produces a permanent geo-referenced record of what you installed, where it runs, and how deep it sits.
Delivered as a KML for easy reference, a Shapefile for GIS workflows, or a DXF for CAD — or all three. Photos and install attributes ride along with each feature. Useful for your own records, client deliverables, or warranty and liability documentation.
