<DIV>Hi Benjamin</DIV>
<DIV> </DIV>
<DIV>You need to establish some coordinate reference system to use. Could be metres, starting with 0,0 in the south-west corner of your floor. The raster should haev a world file associated with it (with a .pgw extension) that establishes the location of the centre of the top left (north west) pixel.</DIV>
<DIV> </DIV>
<DIV>the Map file and OpenLayers will have to know the extents of your floor in your coordinate system.</DIV>
<DIV> </DIV>
<DIV>regards,</DIV>
