How Utility Data Becomes GIS Layers

Utility data becomes useful when it’s structured, repeatable, and tied to a coordinate system. Turning field observations into GIS layers helps municipalities, engineers, and asset managers make better decisions over time.

Field Capture

Field capture typically starts with identifying features and documenting what is actually present: utility paths, access points, appurtenances, and any visible attributes.

GNSS Positioning

Using GNSS-enabled workflows (such as Trimble Catalyst DA2), feature locations can be captured in the field and tied to real-world coordinates. Accuracy depends on environment, workflow, and collection standards.

Attributes & Structure

GIS value comes from attributes, not just lines on a map. Common attributes include:

• Utility type (water, electric, fiber, sewer, etc.)
• Material (when known/visible)
• Diameter/size (when known/visible)
• Depth notes (when verified)
• Confidence/verification notes

Deliverables That Actually Help

A good deliverable is one that can be used again. Depending on scope, that may include:

• Feature layers (hosted or file-based)
• Shapefiles / geodatabases
• Maps or exhibits for project files
• Photo documentation

The goal is long-term clarity: fewer unknowns, fewer repeats, and a system that becomes more accurate over time instead of resetting with every project.
