 In rapid mapping, it is always important to have access to various sensor types, resolutions, and satellites. Indeed, SAR sensors are able to detect through clouds and during nighttime 
 (which is particularly useful during flood and storm events), while optical sensors benefit from of multi spectral bands to better analyze and classify the crisis information.

 This is why SERTIT decided to decouple the sensor handling from the extraction algorithms: the latter should be able to ingest semantic bands 
 (i.e. `RED` or `VV`) without worrying about how to load the specific sensor band or in what unit it is.  
-The assumption was made that all the spectral bands from optical sensors could be mapped between each other (see Figure 2), in addition to the natural
-mapping between SAR bands.

+Thus, thanks to **EOReader**, these tools are made independent to the constellation:  
 ✅ the algorithm (and its developer) can focus on its core tasks (such as extraction) without taking into account the sensor characteristics 
 (how to load a band, which band correspond to which band number, …)  
 ✅ new sensor addition is effortless (if existing in **EOReader**) and requires no algorithm modification
