THE CITY OF CHARLOTTESVILLEVIRGINIA, USA
Development of A Web-Based Solar Map
Built an interactive ArcGIS web application mapping solar potential for Charlottesville buildings, enabling property owners to assess rooftop PV suitability and estimate environmental benefits. The platform calculates total roof area, usable space, system size, and potential energy savings to reduce utility bills and promote clean energy adoption. Features a user-friendly map viewer interface with detailed property-level insights.
THE TOWN OF PURCELLVILLEVIRGINIA, USA
Development of Online Adopt-A-Hydrant Platform
Built an interactive, map-based platform for Purcellville's Adopt-a-Hydrant program, enabling residents to adopt local fire hydrants and keep them clear of snow during winter storms. The system allows citizens to view available hydrants, sign up, and name their adopted hydrants, while providing town staff with administrative tools to manage volunteers, track signups, and coordinate cleanup reminders for community safety.

Four Things That Actually Matter
Not the usual vendor promises - specific, verifiable reasons why experienced GIS buyers choose us.
Deployed at national scale, not just piloted
We've built GIS systems that manage national infrastructure. LGED's national rural road network, Bangladesh's NSDI, and the World Bank's Urban Resilience system across three city corporations are production systems serving thousands of government users - built and deployed by our team, not handed off to a systems integrator.
→ LGEDNSDI (JICA)GeoDASHWorld Bank URP
We own the full GIS delivery chain
From field survey design and enumerator training - Mergin Maps, QField, Android GPS apps - through geodatabase architecture in PostGIS and tile service configuration in GeoServer, to production web and mobile applications. We don't hand off the difficult parts to subcontractors. One team, end to end, with QA/QC documentation at every stage.
→ 33,000+ buildings mapped15+ citiesPan-city surveys executed by our team
Remote sensing and spatial ML, not just map viewers
Most GIS development firms stop at web mapping. We build the analytical layer too - satellite imagery pipelines, ML-based classification and change detection, and automated spatial analysis at national scale. Our Sentinel-2 platform generates monthly freshwater surface maps covering all of South Africa, running as a production system, not a research prototype.
→ Sentinel-2ML classificationGDAL/rasterio pipelinesNational-scale coverage
We embed in your team and your codebase
We work inside your existing platform, your workflow, and your delivery rhythm - not alongside it. Whether you're extending a spatial SaaS product, scaling to new markets, or shipping a complex new GIS feature, we integrate cleanly with your team. Post-delivery, we stay engaged: performance monitoring, feature iterations, and ongoing engineering support as needed.
