We just finished a rather extensive round of testing all of the major software packages for viewing raster data and IMAGINE was the clear winner in terms of speed and performance. Not to say that we don’t want more :). I don’t recall ever receiving a memory error in IMAGINE so I bet there is not a whole lot to be gained in a move to 64-bit. When performing vector geoprocessing in ArcGIS I continually run into memory issues, but last I heard from ESRI they were not planning on moving to 64-bit. Visualizing LiDAR point clouds is one area where 64-bit support has been a real game changer, so much so that it appears that graphics card memory and not system memory will be the limiting factor.<BR/><BR/>I am guessing the Apple fans will want you to provide support for the upcoming Snow Leopard OS. It is reported to support 16TB of RAM. In such a situation one could load everything into memory.Jarlath O'Neil-Dunnehttps://www.blogger.com/profile/08554942198390184997noreply@blogger.comtag:blogger.com,1999:blog-1883623975517863992.post-24266218395271664572009-02-12T18:01:00.000-05:002009-02-12T18:01:00.000-05:00At some point in the next 3 years we will see soli...At some point in the next 3 years we will see solid-state hard disks become stable, cheap and very fast. At this point we will see large jumps in performance. Nevertheless, we need to touch the hard disk once for each pixel when reading and once when writing. Let's make sure we do that now, so when solid-state hard disks are ready, we will be ready to fly...Paulhttps://www.blogger.com/profile/13894940986452821719noreply@blogger.comtag:blogger.com,1999:blog-1883623975517863992.post-57694651695168044062009-02-11T04:30:00.000-05:002009-02-11T04:30:00.000-05:00I agree.

I had a while ago extremely good discussion in erdas-l email list about this and we agreed that you need some decent hardware driven disk management to make things be really fast. <BR/><BR/>This issue probably remain as it is also in 64-bit os. Not even a 64-bit os is possible to have RAM for terabyte imagery and you still need hard drives.<BR/><BR/>However 64-bit is coming anyway - it is important and it is needed. It may not be the final solution of everything but it will still be a big issue for many cases.<BR/><BR/>timoAnonymousnoreply@blogger.com
