The data

Target file is rios.shp. The reference system of this file is SAD69, which has SRID 4618. However, QGIS and gdal have the wrong parameters for this reference system and will do an incorrect conversion do WGS84. In ogr2osm, the option -e 4618 should not be used. Instead, use -p '+proj=longlat +ellps=aust_SA +towgs84=-67.35,3.88,-38.22,0,0,0,0 +no_defs' .
