Spatial Adjustment

Accurate spatial correction of roadway assets for reliable GIS and transportation datasets. We refine and relocate roadway asset geometries using GIS data, imagery, video, and project specifications to deliver spatially accurate, specification-compliant mapping data.

Overview

Refining spatial accuracy for roadway assets — VMAPStech applies rigorous GIS-based spatial adjustment to align roadway assets with their true geographic position and geometry. By integrating GIS datasets, imagery, video, and project specifications, we deliver accurate, validated, and specification-compliant asset data for transportation and infrastructure applications.

How we do it

Data & Specification Review

We assess GDB datasets, ESRI maps, imagery, video, web references, and project specifications to establish the spatial adjustment framework.

Spatial Assessment

We compare existing asset locations and geometry against authoritative spatial and visual references to identify positional discrepancies.

Asset Adjustment

We precisely relocate point assets and refine linear asset geometry to reflect their verified geographic position.

Quality Control

We validate adjusted data for duplicate assets, incorrect locations, attribute integrity, and database field consistency.

Quality Assurance

We perform completeness checks, specification compliance reviews, and targeted spatial validation across the processed dataset.

Final Delivery

We deliver validated, spatially adjusted GIS data in the required ESRI formats, ready for downstream transportation and asset-management applications.
