I have 18GB ecw image, how to cut down to make smaller file sizes/tiles?

[BenVan_Kesteren1]

Hi,

I have been given an 18gb ecw file from the company that flew over our city a couple of years ago, but nobody ever asked to receive this image in smaller tiles. Now i am trying to use the aerial photography on our survey equipment I am tryin to cut the image up into 500mb files.

Has anyone ever done this with GIS, and if so was it difficult? I would prefer to try do it myself as the company that flew the imagery are happy to charge us a pretty penny to do it for me.

Thanks

This question was raised again here at work, and a solution was found here.

Just tidying up my threads and thought I would mark it as solved with the solution used.

Cheers
