Laying the Foundations for a National Building Outlines Dataset
summary
National building outlines dataset now holds about 2.8 million outlines captured against NZ aerial imagery, built with a QGIS plugin and managed in Postgres/PostGIS, Sphinx docs and Travis CI. Processing runs chronologically to merge duplicates, assign persistent IDs, and classify relationships as matched / added / removed / related, with 193 DB tests and 112 plugin tests. Data already aided a Kikuna earthquake response; releases include a current snapshot and a full history dataset showing lifespans and removals.
