Introduction
This block provides high-resolution 8-bit Getmapping aerial images. These images are covering Great Britain and most of the areas have been captured multiple times since 1999.

How it works
| Supported JSON parameters | Default value | Min | Max | Examples | |
|---|---|---|---|---|---|
zoom_level | 19 | 2 | 19 | "zoom_level": 19 | |
imagery_layers | composite_best_UK_250mm | n.a. | n.a. | "imagery_layers": ["composite_best_UK_250mm"] | |
bbox/contains/intersects | null | n.a. | n.a. | Please check the examples from the JSON parameters. |
Disclaimer
Getmapping provides all the image tiles intersecting/covering an AOI or bounding box. The smaller the zoom level, the larger the tiles and the larger the credit consumption (the pricing is per km2). We strongly advise not changing the zoom level value during job configuration.
