This block provides high-resolution 8-bit Hexagon aerial images, either as downloaded or streamed products. These images are acquired with Leica ADS100 and Leica DMC III large format digital airborne sensors on a yearly basis in the USA. The datasets are available starting with 2014.

The maximum AOI size is 25 sq. km. By default, the most recent image is returned. The streamed image or any derived dataset that contains the original pixel values cannot be downloaded. For more information about the end user license agreement of the streamed product, please refer to the Marketplace.
The acquisition date and other metadata are displayed in the file
data.json, which is generated along with the downloaded Hexagon image:

|n.a.||25 sq. km.||Please check the examples from the JSON parameters.|
HxGN provides all the image tiles intersecting a certain AOI or bounding box. The smaller the zoom level, the larger the tiles and the larger the credit consumption (the pricing is per sq. km). We strongly advise not changing the zoom level value during job configuration.
