Cartography differs from standard OSM
Tiles come from a renderer built for field contrast rather than from the Mapnik stylesheet. The result reads as OpenStreetMap, but feature hierarchy, label placement, and symbolization differ in places. The explorer draws the same tiles the GeoPackage contains, so the styling can be checked against your own requirements before purchase.

Coverage is partial, and the map is the authority
NAIP is flown state by state, so the published extent is a bounding box with holes in it. 934 one-degree cells carry imagery, against 976 for the OpenStreetMap layer. A cell inside the extent that has no file cannot be selected and is never charged for. Check the map explorer before planning around a given area; it is the authoritative answer on what is purchasable.
MG3 seams along county boundaries
The 2018–2019 baseline was cut from MrSID MG3 county files. MG3 carries no alpha channel, so color steps and edge seams can show along the mosaic boundaries. They are visible in the explorer before download, and the $1.00 price reflects both the vintage and the artifacts.
2023 to 2025 vintages in production
Pipelines for the 2023, 2024, and 2025 NAIP vintages are in progress. Those sources are MrSID MG4, which carries native alpha transparency, so the mosaic seams resolve and resolution improves. Not yet published.

Sold whole, not by cell
These are not cut to the one-degree grid the raster products use. They arrived as one zip per continent and are sold that way, so choosing this layer in the map explorer switches the map from cells to regions.
OpenStreetMap terms travel with it
The features are derived from OpenStreetMap, so the Open Database License applies to the data inside: attribution and share-alike obligations pass to you along with it. The licensing page states what applies to each product.
