NAIP Imagery 2012 MrSID to other format

[AlexGole]

Hi all,

I am trying to get the NAIP 2012 imagery for Humboldt county as efficient as it can get to get a team of editors/digitizers started. I downloaded 2012 MrSID NAIP imagery for Humboldt (2Go) last week. It looks great, but it does not seem like it is the most efficient  when it comes to drawing in ArcMap. I was wondering what format should I export it to?

==> TIFF. No because size limitation is 4Go.

==> JPEG?

==> ESRI grid??

All I am looking for here is a way to display the raster faster and with (still) a pretty high quality.

Thank you,

Alex

The fastest imagery delivery system is Caching.

And you can go mobile with a Tile Package:

My thought was that I should compress NAIP imagery first with JPEG and then cache the imagery. But maybe only caching is enough?

Thanks Alex

MrSID is already massively compressed.  Converting MrSID to JPEG would result in much larger imagery files.

That is right, Mr SID is massively compressed (more so than JPEG or TIFFs). I mean re-compress it in form of a JPEG. Based off this article, it seems like although the JPEG are "bigger" at take more space, they still draw faster.  A look at raster compression, pyramids, time, and space | ArcGIS Blog
