GIS Feature Mapping

PRODUCTS

GIS feature mapping converts airborne LiDAR and aerial imagery datasets into structured spatial data used for infrastructure mapping, municipal GIS systems, and spatial analysis.

OGL performs feature extraction, data structuring, and GIS database development to deliver GIS-ready datasets that integrate directly into platforms such as ArcGIS and QGIS.

Typical deliverables include vector feature classes within geodatabases, supporting asset management, planning, and engineering workflows.

ATTRIBUTE DATA & GIS STRUCTURING

Mapped features are supported by structured attribute data, enabling analysis, querying, and system integration.

OGL develops datasets aligned with client-specific schemas, ensuring seamless integration into existing GIS environments.

Typical Workflows

Attribute creation and population
Dataset validation and QA/QC
Spatial joins and attribute enrichment
Schema standardization

PRODUCTS

GIS INTEGRATION
