# Orthomosaics

Orthomosaics are geometrically corrected aerial images stitched together into an accurate, scaled map layer. 

### Viewing an orthomosaic

As you zoom into an area with orthomosaic coverage, the image layer appears directly on the map, replacing the hexagonal coverage tiles.

### Multiple capture dates

The orthomosaic layer always shows the most recent capture available for an area. To view an older capture instead, use the date range filter in the Layers panel to narrow the window; see [Layer Management](/spexi-world-viewer/interactive-blocks.md).
