336,378 parcel features, 110 attributes, 67% weighted attribute fill. Reprojected to WGS 84 (EPSG:4326); geometries repaired where invalid. Attribute fill rates measured on a 200,000-feature sample. Point-in-time snapshot. No cross-county schema normalisation.
Each row is a distinct point-in-time snapshot of Collin County, not a revision of one file. Parcel counts move between vintages for real reasons — subdivision, consolidation, annexation, a re-survey — so a jump in the count is information rather than an error. This county's record here spans July 2018 to December 2019.
Archive vintages are released once they are old enough to be non-competitive; community vintages are contributed by users and published as soon as they pass verification. Both are free.
