What is NUPSI?
==============

**NUPSI - NUts Production Storage and Imagery service** is a web
application designed to provide intuitive access to Copernicus data. By
focusing on the "what, where, and when," NUPSI uses user-friendly
controls and application-driven visualizations to help you access,
interpret, and compare satellite information for your area of interest.

Area of Interest (AOI) Focus
----------------------------

NUPSI displays Copernicus data over predefined administrative
boundaries, specifically European
`NUTS <https://ec.europa.eu/eurostat/web/nuts>`__ (Nomenclature of
Territorial Units for Statistics, from NUTS0 to NUTS3 levels), as well
as custom AOIs.

| Currently NUTS 2021 Nomenclature has been used. Migration to NUTS 2024 is on the roadmap.

Application-Driven Visualisation
--------------------------------

- **Track changes over time** using a seamless timeline interface.

- **Visualize parameters** from multiple perspectives (e.g., vegetation,
  soil moisture, urban dynamics).

- **Access pre-processed Sentinel mosaics** or request custom data
  extractions.

Available Pre-Processed Datasets
--------------------------------

- **Sentinel-2 Level-2A:** Cloudless monthly mosaics (Bands: B02, B03,
  B04, B08, B8A, B11, B12)

- **Sentinel-1 Level-1 IW DV GRDH mosaics**

How to select Area of Interest
==============================

The NUPSI homepage features an interactive globe with preloaded NUTS
boundaries for seamless browsing of European data.

|image1|

You can select an Area of Interest in several ways:

1. **NUTS level navigation:** Zoom into the map. The displayed NUTS
   level will dynamically update from country (NUTS0) to local areas
   (NUTS3)\ |image2|

   1.1. Download a GeoTIFF of the selected area by clicking the download button |image211|
   
|   Note: In order to see the download button as active, the user must be logged in.
|    Currently it is possible to donwload only NUTS level 3 regions or communes, the GeoTIFF is limited to max 5000x5000 pixel.  


2. **Search Bar**: Use the integrated **search bar for European communes (GISCO)** to
   find smaller administrative areas inside NUTS coverage.

3. **Freehand drawing** Click the drawing tool icon |image3| and draw a
   shape point-by-point (right-click to close it).

4. | **GeoJSON download and upload –** |image5|

   4.1. Once you have created your freehand section, you can download it as a GeoJSON file using the download icon |image211|

|   Note:In order to download a GeoJSON cutline, the user must log in first

   4.2. Upload your own GeoJSON file using the upload icon |image211|

   | The following pop-up will appear on the left side

Browse and Visualise Systematic Data Offer
==========================================

Navigate country level (NUTS0) **monthly mosaics**. You can visualize each layer along a timeline.

|image7|

**First, select your area.** Then, choose a visualization.

NUPSI uses common Sentinel-based visualizations (e.g., **S2 TCI**,
**NDVI**, **NDMI**, **S1 RGB ratio**, **SAR Urban**) to support various
applications. The data is organized in three menus:

|image8|

Explore Menu
------------

Ideal for non-expert users. Start with an application need (e.g., "Soil
Moisture") and be guided to the relevant data layers (e.g., NDMI).

- Each application includes a brief description.

|image9|

Satellite Menu
--------------

For expert users who want direct access to specific missions, bands, or
indices. This menu provides the same visualizations but organized by
satellite mission (e.g., Sentinel-1, Sentinel-2).

|image10|

Timeline viewer
---------------

Navigate through time using the monthly timeline. Use the arrows to
scroll through available data and monitor the evolution of your area.
