Digital ROW Utilities (DRU) captures utility points, lines and photos with documented methods and reported uncertainty, browses public GIS reference data, and exports reviewable records.

Capture Assets

Walk the site. Tap to log. AI detects hydrants & infrastructure in real time.

2

Certify In Field

Review ASCE-oriented attributes and OCR suggestions against the original field evidence before sign-off.

3

Export & Submit

11 formats: GeoJSON, Shapefile, KMZ, DXF, ASCE 75-22 JSON, PDF Report & more.

Point & Linear Capture

GPS trace for full pipe runs with method auto-logged.

AI Asset Detection

AI-assisted detection of hydrants, manholes, and valves. Decision-support only — verify all output.

Material Cert OCR

Scan cert tags — material, diameter, wall thickness auto-fill instantly.

AR Visualization

Overlay WFS utilities in live camera, color-coded by utility domain.

ASCE-Oriented Record Review

ASCE-oriented fields and validation support review. A complete form, signature or hash does not independently establish compliance, a utility quality level, survey accuracy or a professional credential.

LiDAR Depth Measurement

LiDAR-assisted depth capture on supported iPhone Pro models. Field results vary; verify against your project's accuracy requirements.

11 Export Formats

GeoJSON, CSV, KML, KMZ, DXF, Shapefile, PDF Report, ASCE 75-22 JSON & more.

Publish to Your GIS

Where GIS publishing is enabled in the installed build, use your authorized destination and credentials, review field mapping and queued changes, then reconcile the result with the receiving system.

AES-GCM Encryption

Authenticated AES-GCM encryption option for sensitive infrastructure data.

SHA-256 Audit Trail

Cryptographic integrity verification generated per export session.

GNSS / RTK Support

Location records retain the observed method and reported uncertainty. External GNSS and corrections depend on the installed build and compatible receiver. An NTRIP connection does not establish a corrected phone position or an RTK fix.

WFS Catalog

40,265 nationwide utility data sources — Electric, Gas, Water, Telecom. Ships with a curated set offline; the rest load on demand.

18 State CORS Networks

Iowa IaRTN and 17 other networks for GPS accuracy (coming soon).

Skip the export-and-reimport shuffle. Push captured, ASCE 75-22 as-builts straight into your own GIS of record — no shared logins, no middleman database. You connect your server, you keep control, and every write is made with your own account's permissions.

1

Connect Your GIS

Add your own ArcGIS hosted feature layer with a portal sign-in or token. Credentials stay in the device Keychain — never in the app or a shared key. QGIS Server / WFS-T is on the roadmap.

2

Check Field Mapping

Before publishing, DRU reads your layer's schema and shows exactly which ASCE attributes will be stored and which have no matching field — so nothing is silently dropped.

3

Publish With Your Permissions

Features write to your layer via the native GIS API in WGS84, carrying Quality Level, positional accuracy, and SHA-256 provenance. Your server decides who can write what.

🔐

Your Data, Your System of Record

DRU never holds a shared write key. Publishing uses your credentials, so your GIS enforces what's allowed — captures land in the authoritative layer your team already trusts, with full ASCE 75-22 attributes intact.

Every agency takes permits differently — some run an online portal, some want a completed form by email, some still file at a counter. DRU builds one application package that works for all of them, and tells you which route the jurisdiction you typed actually uses.

1

One Application Package

A single PDF a reviewer can read, print and route — applicant, work, schedule and ASCE 75-22 data quality, a full-page work-area map, and every polygon vertex written out to six decimals. The geometry survives even if a mail gateway strips the KML.

2

Routed to the Right Place

DRU knows how each jurisdiction accepts a request and shows it on the form — the portal to open, or the permit office to email, plus what that agency expects attached. Unrecognised jurisdictions say so rather than guessing at a permit office.

3

Status Without Retyping — coming soon

Where an agency publishes issued permits as open data, DRU will read the status back in the agency's own words instead of asking anyone to re-key it. No credentials involved — the data is already public.

🏛️

Direct Submission — Enterprise — by request

Some agencies can accept a permit straight from DRU, with no re-entry in their portal and status read back as they update it. It depends on the platform your agency runs and on that agency enabling it, so it starts with a conversation rather than a switch — ask us about yours. Your agency sign-in stays in the device Keychain; we never hold it for you.

DTCD Integration

Links every utility install to a live work zone via Digital Traffic Control Diary. DRU alerts you when no work zone is linked — open DTCD directly from the app.

Audit Trail

Give your crew a clear
path from capture to handoff.

Ten practical lessons cover project setup, point and line capture, photo evidence, OCR review, public GIS, AR limits and a verified export. Use the 22-page handbook for a crew session, with a field lab, trainer observations, printable checklists and a knowledge check.

No sign-up. iOS workflow. Android development features differ.

National GIS / Next iOS build

Learn the new Reference layers.

The October expansion adds 278 queryable services and one national soil portal after discovery searches across all 50 states. Learn how roads, wetlands, flood context, parcels, ROW/easements and regional soils support project planning.

Requires a new iOS release. Parcel, ROW, physical fiber and soil-map coverage varies by location; reference layers are separate from underground AR assets.
