Sources
Source context stays attached.
Community evidence, municipal facts, and secondary reporting each have a different role. Attribution and release packaging remain visible.
Explore the detailsWhere does the information come from, and what is reusable?
Explain source classes, licensing boundaries, build identity, and data-access limits.
Three source classes, three different jobs.
Can every source create the same kind of record?
OpenStreetMap and ODbL: Community observations can support an attributed, signed, reproducible release package. They remain incomplete, non-official, and not real-time.
Municipal facts: Official publishers can support product-authored, source-linked facts when dates, jurisdiction, precision, review state, and permitted use remain intact.
Secondary corroboration: News and reports can support discovery or corroboration. One secondary report cannot activate a public record or silently change its status.
Source classes retain distinct authority and use rules.
News or RSS as direct activation authority.
Open data still comes with obligations.
What must ship with an OSM-derived build?
OSM-derived release data ships with persistent OpenStreetMap attribution, the Open Database License, exact provenance, signed publication, and a reproducible build identity.
Each distributed build identifies the corresponding database or complete transformation inputs needed to examine the same published evidence package.
- Release scope
- National Map index for eligible ALPR records, with incomplete community-source coverage.
- Build access
- Every distributed build names its corresponding database or reproducible transformation package.
- License
- Open Database License 1.0, attribution and share-alike treatment required.
Persistent attribution, exact provenance, signed publication, and corresponding data are required.
Official, complete, or independently verified merely because coordinates exist.
Build identity is dated, not timeless.
Can the site publish one national camera count?
Every compact index build has an exact source identity, sequence, date, and content binding. Nova Vista does not promote its row measurement as a camera count, because rows can differ in geometry, status, and physical meaning.
A source build has an exact identity and date.
A combined total of cameras or a permanent national count.
Trust is in the details.
A boundary is part
of the feature.
Nova Vista keeps route neutrality, source provenance, incomplete coverage, privacy, and safe-use limits visible wherever they affect what a record can mean.
