[Want to Ask] Calibrate geotiff map

[kungz]

Hello everyone, I have calibrate geotiff map (.tif.ovr) and I want to use it as offline maps on locus. It is possible? and if it is possible, how to do that? I was copy to vector maps folder but locus can't detect it.

Thank you

have you checked the GDAL library (http://www.gdal.org/) in the mapc2mapc-package?
maybe other tools can read .ovr  (http://trac.osgeo.org/gdal/wiki/SoftwareUsingGdal)
