Hello JAXA Earth Observation Center team,

I am writing to inform JAXA in advance about our intended commercial-purpose use of the
AW3D30 (ALOS World 3D - 30m) dataset, in accordance with JAXA’s Terms of Use of Research Data.

Product name:
- Planetka (Blender extension) / "Planetka - the Earth"

Product link:
- https://www.planetka.io
- https://superhivemarket.com/products/planetka-256k (planned product page; not released yet)

Data used:
- AW3D30 (ALOS World 3D - 30m) provided by JAXA
- Used to generate derived raster textures (tiles) for elevation and related masks in the
  extension (Planetka texture dataset folders "EL" and "WT").

How it is used:
- End users install the Planetka extension for Blender and use the included derived textures
  to render still images and animations of the Earth surface.

Distribution / commercial context:
- The Planetka extension (including the derived AW3D30-based textures) is sold commercially
  as a digital product (Blender add-on).

Modifications:
- The AW3D30-derived textures are retouched/processed for visual clarity and performance
  (e.g., artifact/error removal and optimization for fast loading).

Attribution:
- We will credit the source as: "AW3D30 (ALOS World 3D - 30m) provided by JAXA."

If you need any additional details (e.g., exact geographic coverage, file list, or
release/version identifiers), please let me know and I will provide them.

Best regards,
