Designed on top of the interactive framework `sepal_ui <https://github.com/12rambau/sepal_ui>`_, this module allows users to extract ALOS K&C mosaics.
- extract ALOS Kyoto & Carbon (ALOS K&C) mosaics by JAXA;
- display the mosaics in interactive maps; and
- export the mosaics as Google Earth Engine (GEE) assets and/or SEPAL .tif files.

Necessary inputs include:

- an area of interest (AOI)
- a year
- select filters

The user will be able to display the mosaic in an interactive map and export it as a Google Earth Engine (GEE) asset and/or SEPAL .tif file.

The three-step process is described in the sections below, as well as presented in the following video tutorial.
