I have a large Mr Sid raster and would like to make it render faster in ArcMap. I could get access to the Spatial Analyst extension, but before I go to the considerable trouble to get the extension, I'd like to query the group about whether that extension is what I should use to break up my Mr Sid into 4 chunks or tiles. What other app or workflow should I use? My understanding is that ArcMap won't do the tiling, itself, without degrading the raster resolution.
I hadn't thought of setting a scale range for a raster; that's a good trick to keep in mind. I realize that MR Sid is an image format. What format would you recommend changing the raster to to enable us to change it to a format that we can tile?
Thank you for the prompt help,
Your point about the file size greatly expanding when we change from the Sid format is really helpful. I'm wondering if the increased file size, in another format, will make it render faster. I agree with you that accessing the ArcGIS.com imagery is an option, unfortunately, we're dealing with historical imagery. From what format, other than SID, can we tile the images into smaller chunks? would spatial analyst allow us to tile?
