London rooftops solar-qualified remotely. 90% reduction in field surveys.
A precision clean-energy operating model for city-wide solar feasibility and carbon reduction — remote identification and analysis of south-facing residential rooftops across London, England. Roof orientation, shading and yield filtered before installation crews leave the depot.
90% reduction in manual fieldwork. Every pound of solar capex directed at a roof with full sunlight exposure.

Challenge
To meet national climate goals, the UK government required a rapid, large-scale assessment of residential buildings suitable for solar panel installation. Manual surveying was too slow and costly to meet the project’s timeline. Only south-facing roofs are commercially viable; urban density creates complex shading patterns from trees and adjacent buildings; and analysing thousands of individual rooftops across the London suburbs required a process that bypassed traditional ground-based site visits.
Approach
SBL Infotech’s MMS platform runs city-wide sustainability analysis: “ideal roof” criteria are established up front (slope, orientation, zero-shade tolerance); a remote-sensing team specialised in residential rooftop geometry calculates roof area and sunlight exposure using Google Earth, Google Maps and Roofray; and 2D / 3D cross-referencing confirms shade-free, south-facing alignment before any actionable site enters the rollout database.
Outcome
A city’s solar potential, rebuilt as a product. By digitising the feasibility study, the platform allows energy providers and government bodies to scale renewable-energy uptake across entire metropolitan areas without the bottleneck of physical site visits — accelerating proposal-to-installation timelines and directly contributing to urban carbon-neutrality targets.

Reliving History with Geospatial Intelligence
260 years of fragmented historical maps transformed into a georeferenced spatial database for anthropological and land-use analysis. A prominent US university needed to study the historical evolution of Uxeau, France, across multiple centuries of land ownership, taxation, and agricultural activity. The research depended on digitising and harmonising vintage maps dating back to 1759 — each with different scales, formats, and levels of degradation — into a single spatially accurate GIS environment suitable for comparative analysis. 260+ years of historical mapping digitised and layered. Lambert II precision georeferencing using Esri GIS tools. Multi-era land parcel and feature extraction delivered at scale.
"Historical GIS digitisation transformed fragmented archival maps into a searchable spatial database, accelerating anthropological research and long-term land-use analysis. "AI-Powered CT Scan Annotation
30,000+ CT scans annotated at 98.9% segmentation accuracy for AI-driven radiology models. A US-based MedTech AI company developing radiology models for tumour detection and analysis required clinically precise annotation support to accelerate model training and validation. Existing workflows faced rising costs, limited access to qualified medical annotators and growing compliance pressure around handling sensitive patient imaging data.
HIPAA-compliant medical annotation workflows improved radiology AI accuracy, accelerated tumour detection model training and reduced operational costs significantly.Mortgage Foreclosure Data Management
40%+ faster foreclosure data processing with 50% higher accuracy across multi-county property records. A US-based mortgage data company managing property intelligence across more than 155 million properties and 3,000+ counties required a scalable operational model for foreclosure data collection and processing. Their existing workflows relied heavily on manual back-office operations, creating delays, inconsistencies and rising operational overhead across fragmented government data sources.
Standardised foreclosure processing improved nationwide property data accuracy, reduced turnaround times and created a scalable mortgage intelligence operations framework.
