RustGIS 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.

OpenAtlas: 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.

Jacksonville 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.

GeoRescue: 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.
