How GeoVisual Search works
Tile source maps
We divide the globe into a grid of tiles—and then use multiple overlapping grids, capturing features that would otherwise run across tiles.
For each image tile, we use a deep neural network to extract features, such as shapes, colors and texture. These features can include the visible and non-visible spectrum.
Given a query image, we calculate a “visual distance” between the query features and the features extracted from each image in the comparison set.
We match the tiles with the smallest “visual distance” to the query tile.

Descartes Labs created two base layer map composites for GeoVisual Search utilizing Landsat 8 for global coverage and NAIP for the US.
