Sources, dates and limits
Each source’s verification date appears in the table. Retrieval time is not the data update date. Small city-wide layers use the full extent; larger layers depend on the visible area. Reference publications retain their original retrieval date. Each page contains up to 500 features: up to 2 MiB for external services and 4 MiB for local publications. Reference publications load matching pages, up to 5,000 features and 8 MiB per query. External services may return partial samples, identified in the viewer.
