<p>The ESA Orthorectified Map-oriented (Level 1) Products collection is composed of MOS-1/1B MESSR (Multi-spectral Electronic Self-Scanning Radiometer) data products generated as part of the MOS Bulk Processing Campaign using the MOS Processor v3.02.</p>

<p>The products are available in GeoTIFF format and disseminated within EO-SIP packaging. Please refer to the&nbsp;<a href="/documents/d/earth-online/mos-product-format-specification" target="_blank">MOS Product Format Specification</a>&nbsp;for further details.&nbsp;</p>

<p>The collection consists of data products of the following type:&nbsp;</p>

<ul>
	<li><strong>MES_GEC_1P</strong>: Geocoded Ellipsoid GCP Corrected Level 1 MOS-1/1B MESSR products which are the default products generated by the MOS MESSR processor in all cases (where possible), with usage of the latest set of LANDSAT improved GCP (Ground Control Points). These are orthorectified map-oriented products, corresponding to the old MOS-1/1B MES_ORT_1P products with geolocation improvements.&nbsp;</li>

<p>The GEOSAT-2 Spain Coverage collection consists of imagery covering Spain, including the Balearic and Canary islands, acquired by GEOSAT-2 between March and November of 2021.</p>

<figure class="centered-mobile-centered"><a data-lightbox="Spatial coverage of the 2021 collection." data-title="Spatial coverage of the 2021 collection." href="/documents/d/earth-online/spatial-coverage-of-the-2021-collection"><img alt="Spatial coverage of the 2021 collection." class="centered-mobile-centered" src="/documents/d/earth-online/spatial-coverage-of-the-2021-collection-tm" /> </a>

<figcaption><i><a href="/documents/d/earth-online/spatial-coverage-of-the-2021-collection">Spatial coverage of the 2021 collection.</a></i></figcaption>
</figure>

<p>The available imagery have a geolocation accuracy of &lt; 4 m RMSE, a cloud cover percentage of &lt; 10 %, and were acquired at an off-nadir angle from -30° to 30°.&nbsp;</p>

<p>The following product types are available:</p>

<ul>
	<li><strong>Pan-sharpened:</strong> A four-band image, resulting from adding the information of each multispectral band to the panchromatic band. The fusion does not preserves all spectral features of the multispectral bands, so it should not be used for radiometric purposes. Resolution 1 m; Bands: All.</li>
</ul>

<ul>
	<li><strong>Bundle:</strong> Panchromatic (1 m resolution) + Multispectral bands (4 m resolution): five-band image containing the panchromatic and multispectral products packaged together, with band co-registration.</li>
</ul>

<p>The available processing level is L1C orthorectified: a calibrated and radiometrically corrected product, manually orthorectified and resampled to a map grid.</p>
