Urban Boundary Digitisation Project

A large-scale geospatial digitisation initiative transforming paper-based urban drawings into searchable, engineering-grade city intelligence. SBL converted georeferenced plot maps into enriched Bentley CAD datasets — enabling faster zoning decisions, accurate property assessments and scalable digital urban planning across Spanish municipalities. High-precision plot boundary digitisation delivered at city scale. Bentley CAD-compatible outputs enriched with zoning and property metadata. Faster urban planning and taxation workflows enabled through searchable spatial data.

Industry: Energy & Utilities

City-scale: Plot boundary digitisation
Bentley CAD: Engineering-grade spatial outputs
Enriched: Zoning & property metadata

Challenge

Urban planning teams relied on aging paper-based georeferenced drawings that slowed land-use planning, infrastructure development and property taxation workflows. The data was fragmented, difficult to search and lacked structured metadata required for modern municipal systems. The client needed a scalable way to digitise large volumes of plot boundaries while enriching every parcel with zoning, ownership and spatial attributes compatible with Bentley-based planning environments.

Approach

SBL deployed a dedicated GIS and CAD digitisation team to convert paper-based georeferenced drawings into structured digital city datasets. Using Bentley CAD workflows, SBL mapped plot boundaries with engineering-grade precision while integrating zoning classifications, area measurements and property-level metadata into the spatial framework. Multi-level validation ensured coordinate accuracy, metadata integrity and compatibility with municipal planning systems used across different urban regions.

Outcome

The project transformed static paper archives into a live, queryable urban intelligence platform for planning authorities and data stakeholders. Municipal teams gained faster access to zoning and land-use information, improved taxation accuracy and scalable digital infrastructure for future urban expansion. What was once locked inside physical drawings became a searchable spatial database supporting faster, data-driven city management.

US mining technology provider

Offshore Mine Mapping & Analysis

Dedicated offshore production facility delivering high-precision 3D mine models and stockpile analytics at global scale. A US-based mining solutions company needed a scalable way to process continuous streams of drone-captured mine data from multiple global sites. Existing workflows relied heavily on fragmented surveying and manual calculations, slowing inventory reporting and limiting operational visibility. The client required a centralized production model capable of generating accurate volumetric reports, terrain models, and engineering-ready outputs across large mining operations. Dedicated offshore production facility established. High-precision volumetric reporting delivered at scale. Engineering-grade 3D terrain models processed for global mining operations.

"Centralized offshore mine mapping improved volumetric accuracy, accelerated terrain analytics and enabled scalable global mining intelligence and operational reporting. "

UK renewable energy initiative

Smart Solar Potential Analysis

90% reduction in field-survey costs through remote rooftop analysis across London suburbs. A UK clean-energy initiative needed to identify residential rooftops suitable for solar installation at city scale. Traditional field surveys were too slow, expensive, and operationally impractical for the speed required to support national renewable-energy targets. The challenge was to accurately assess roof orientation, sunlight exposure, and shading conditions across thousands of homes — without sending teams on-site. 90% reduction in surveying overhead. High-speed rooftop qualification across London districts. Accurate south-facing and shade-free roof identification for rapid solar deployment.

"Remote rooftop analysis reduced solar survey costs, accelerated renewable-energy planning and enabled scalable residential solar feasibility assessment across urban districts. "

UK geological data provider

Paleogeological Vector Models

Multi-era geological maps transformed into a projection-accurate digital database for mineral exploration and geoscience research. A UK-based geological data provider needed to modernise vast collections of historical paleogeological maps and analogue records for industrial and research applications. The challenge involved converting fragmented, projection-distorted geological archives into a unified GIS-ready environment capable of supporting mineral exploration, tectonic analysis, and environmental research at global scale. Multi-era geological vectorization completed across historical landmass datasets. Integrated geological, groundwater, and chemical contour mapping delivered in a unified GIS environment. Projection-accurate outputs maintained across global datasets.
