I set up a little WMS server on my home computer, with a few images, 
initially selected by Vitor. If anyone could offer better server 
resources, feel free to step in.

Samuel Vale is also setting up a TMS

The CBERS images could benefit from warping with reference points. 
Multiple OSM GPS tracks are available in Maceio, much fewer inland.

In the meantime, the WMS layer should be shifted in JOSM to match GPS 
tracks and existing OSM data (though some imported roads are sometimes 
not very accurate either).

You can use the following URL in JOSM :

Best wishes,
