Examples of our work
Selected projects. Figures come from each project's public README or page; OpenAtlas figures are from a private prototype.
Open sourcePrint cartography · open sourceRustGIS 1:50,000 Map Sheets of Jacksonville
- Problem
- Print-quality maps need hundreds of labels placed cleanly, with no overlaps.
- Solution
- A Rust engine that places every label at once, curves names along rivers and roads, and outputs true vector PDF/SVG with built-in QC.
- Result
- JAX-01 Jacksonville 1:50,000 sample sheet (v0.7): 781 placed labels, 0 QC failures.
Private prototype3D globe · dashboardOpenAtlas: Your Data on a 3D Globe
- Problem
- Bring your own data to a 3D globe and see it next to real U.S. Census data.
- Solution
- Upload common GIS formats, explore any layer in a dashboard, ask plain-language questions and export.
- Result
- Census data for seven Northeast Florida counties; exports to Excel, Shapefile, GeoPackage, FileGDB or PDF.
Private prototype; no public demo. Screenshot shows Census data and a synthetic sample layer only.
Private prototype · demo on request
Live demoNetwork analysis · utilitiesJacksonville Utility Network
- Problem
- Utility teams need to know which valves isolate a break, who loses power and where hydrant coverage is thin.
- Solution
- Connected water, sewer and electric networks with topology QC, outage traces and hydrant coverage.
- Result
- One fuse trace: 139 customers out. Northside: 12.8% of parcels more than 500 ft from a hydrant.
Pipe and wire networks are synthetic (JEA does not publish them); streets, parcels and hydrants are real public data.
Live demoParcel QC · before/afterGeoRescue: Parcel Data-Quality Audit
- Problem
- Parcel data carries bad geometry, duplicates, overlaps and gaps.
- Solution
- Flags issues and proposes logged repairs on a copy, with a before/after view of each fix.
- Result
- Featured Duval County test case: 408,950 parcels checked, 42 overlaps found.
Test demo, not authoritative: not a survey, title opinion or legal determination.
