Getmapping AOI-Clipped 25cm Base Resolution
25cm Aerial imagery of Great Britain, flown from 1999 to Date. Retrieved using Web Map Tile Services (WMTS).
Description
A data block that 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.
