nltASRM
Address & Spatial Reference Management
One platform for all your address management — desktop GIS power and cloud collaboration over a single authoritative address repository.
nltASRM unifies desktop GIS power with cloud-based collaboration — giving your organization a single, authoritative address repository that serves every department, every workflow, every stakeholder. Built on industry standards and decades of mission experience, it is the single source of truth for address data, backed by Esri integrations and automated QA/QC — serving permitting, dispatch, 911/NG911, and utility workflows.
- Authoritative address repository
- GIS · 911 · CAD/RMS integrations
- Automated QA/QC & validation
- Geocoding & reverse geocoding
How it works
One authoritative address layer, established once and kept current across every system that depends on it.
- 1
Establish the authoritative repository
Build and manage a Master Address Repository (MAR) — the single source of truth for address data, built on FGDC and NENA NG911 standards.
- 2
Validate & standardize
Intelligent rules engines, automated USPS standardization, and geospatial validation eliminate duplicates, resolve conflicts, and keep datasets high-quality.
- 3
Integrate across systems
Connect the authoritative layer to GIS, permitting, 911/NG911, CAD/RMS, and utility applications so every workflow shares the same addresses.
- 4
Detect change & maintain
Automatically detect new addresses, changes, and lifecycle events from permit, 911, and administrative sources to keep the repository current.

Practitioner-in-the-Middle
Results a human expert stands behind
You don’t just get AI results — you get results validated by NLT practitioners. AI-native output is checked against domain expertise and ground truth, corrected where needed, and delivered quality-assured.
A human-expert validation lifecycle you can call on for nltASRM — and across every NLT product.
For addressing specifically, a practitioner can validate new and changed addresses against ground truth and jurisdiction rules before they flow to 911 and permitting.
AI-native system produces results
The product’s AI-native engine generates an initial answer, map, or analysis from your data.
NLT practitioner validates
A domain-expert NLT practitioner checks the result against ground truth and professional judgment.
Refine & correct
Findings are refined, reconciled with the source data, and corrected where the model needs a human hand.
Quality-assured, delivery-ready
You receive results a human expert stands behind — trustworthy and ready to act on.
