how do I geo reference a tif. with aux.xml and tfwx files

[JosephPlessis]

I have a raster dataset at: http://www.env.gov.bc.ca/esd/distdata/ecosystems/TEI_Scanned_Maps/B01/B01-4779/

I need to geo reference the tif file but I have no clue what to do with the assosiated files as I am new to aux.xml, tfwx, etc.

Some clarity on how to properly project these would be awesome! 

thanks a million.

If you add the tiff to a new empty data frame, check the layer's parameters.  The data frame should have been set to the coordinate system since it is the first file that is added.  The proper tool to use should you need to project the raster is

Project Raster—Help | ArcGIS Desktop with discussion here

It is up to you then, to make the appropriate decisions, so don't use the defaults under any circumstances, unless you agree with the cell size, extent, resampling method, etc etc... which can be access in the Environments tab of the tool in its dialog

thanks for the reply dan,

recieved an ERROR -1: unidentified coordinate system, I think it is because the coordinate system info is stored outside the tif in one of the additional files.

everything is in the same folder? It should be used if it is... I will check for an environment setting just in case it isn't

if it is ignoring the world file, you can fix it... see the bottom

so basically it is not reading any coordinate system, ive checked off the use world file box, still not working.

Could be the coordinate system is undefined.  If the coordinate space is correct (ie x,y or long, lat) and you know where it is... try defining it Defining or modifying a raster's coordinate system—Help | ArcGIS Desktop

Your image look great. The coordinate system and the coordinate space are OK.

Just downloaded it and put it in ArcMap and you can see for yourself.

In ArcMap it looks like a single file, you do not need to worry about what file include what information.

If you copy it just copy all the files that start with the same name.

Have fun

SOLVED, silly mistake on my part, I had to right click in the aux.xml web page and "save as".

thanks for all your help!
