Pansharpening
Description
Pansharpening is an image fusion technique that merges high resolution panchromatic images with lower-resolution multispectral images to yield a single high spatial and high spectral resolution image. With UP42, you can easily convert your data into a pansharpened product through a streamlined process that requires only a few clear steps.
Technical information
| Source | Optical tasking or catalog collections (satellite and aerial) |
| Compatibility | - Must be CNAM-compatible - Delivery must have both a panchromatic and a multispectral band |
| Required parameters | - Console: If your chosen input data meets the above specifications you will be able to run your job - API: You will need to input an Output title and the Input data |
| Optional parameters (API only for now) | - Grey weights: You can specify the weights for multispectral bands or use automatically optimized weights by not defining them. Depending on the scene, the algorithm either uses sensor-optimized weights or, if this data is not available, generates new optimal weights. |
| Output | The pansharpened result will be added to your account as a STAC item in a new STAC collection. You can retrieve the resulting data in one of the following ways: - Open the console, go to Data management → Jobs - Retrieve the results via the API |
An example
