Image Files
The image tiles returned from the Tile Product can help visualize flood risk. Leverage the tiles on your own maps to create visualizations of various risk types. Tile layers are placed over the top of your map at a specific zoom level. With enough tiles you can provide your users with multiple zoom levels of flood risk.
The Tile Product provides a 256x256 image map tile that represents flood inundation with 5 depth thresholds. This image is based on the Mercator projection.
The returned image will always provide a result if the correct parameters are provided. This allows for tiles that are requested outside of a boundary to be rendered successfully.
The colored tiles represents four different levels of flooding. These colors are set globally for each product.

Tiles will only return a PNG image if the requested coordinates exist in the tilesets. By default, the tile product will return a transparent tile if there is no data for the requested parameters. It is important to note that transparent tiles will only be returned if the request was deemed successful, which means correct parameters and a valid API key were provided.
For incorrect requests, general errors will be returned.
