Getting started with the Overland GIS map
For acreage around Olivette, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
The free map to start with
Begin with the St. Louis County ArcGIS parcel map; it covers every assessed parcel from Vinita Park to Breckenridge Hills. If you're looking near Olivette, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Vinita Park, write down the parcel ID while you have it open; each records desk in the county uses it to find the file.
A quick look at the area

City limits and county records
Overland sits in St. Louis County, Missouri, so its parcels are on the county's map. For acreage around St. John, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Lots just outside the city limits out by Charlack often follows county rules, not municipal ones.
