Raster Image takes 20 minutes to load.

I have a 16GB Raster that we use for Design/Proposal purposes. Is there anything I could do to potentially improve load time or is this something I'll just have to live with?

Clip the raster?

16GB is a massive raster. Can you make it smaller?

[jmcpherson1982]

At best it would save 1GB maybe 2. The size is largely due to the resolution. I can create 20 scale drawings without pixelation. While clipping does work in those situations It stills leaves me the problem when I have to have the whole campus on a drawing.

Connect it using the Map functionality.  An FDO connection will greatly improve performance.

You really need to cut that size down. You should have a few different files at various resolutions for different scenarios. Having a file that large, as you've already figured out is unmanagable.

Even splitting it up into many tiles for different areas and then attach several of them as the design dictates.

FDO will sample the raster / SID for the area of your view/model space when it demand loads - so will be faster, but beware that I've seen issues that an FDO connection "floats" when you change to paperspace and pan around - sometimes they don't print "true" to their locations....  Watch carefully & use with care!!!

For Example, check out LizardTech's "GeoViewer."  LizardTech holds the copyright (patent) on the SID compression technology and their free viewer has an ability to load SID images & you can zoom in & pan around to your sub-area then export out a .TIF & a .TFW (world file) for Mapiinserting or subsequent FDO to TIF.....  Nice if you want to look at a few parcels and have a SID of the whole county....

Agreed.

Resample the image to a pixels per foot that is adequate for the scale of your drawing.

Also check it with the pixels per inch of your plotter.

It sounds like even at 20 scale you have a resolution in your raster that is unplottable.

I'm definitely going to check that out. Thanks for the reference.
