| Mar 13, 2020 at 16:46 | comment | added | R Thiede | @MajidHojati Apologies, haven't been on the site for a while. The blog I posted this to doesn't belong to me, so unfortunately this article will have been lost. I could not reproduce it in full elsewhere (e.g. here), because it was done as part of my job, and so the material wasn't my own IP, even though I wrote it. | |

| Jun 21, 2017 at 18:27 | comment | added | Matifou | @RThiede had a valid concern: it seems indeed now that the link to the blog is no more valid? | |
| Sep 7, 2011 at 18:57 | comment | added | matt wilkie | thanks! I folded the summary into the answer itself, so it's more self contained (see edit link at bottom left of each answer/question). | |

folded summary into answer

| Sep 7, 2011 at 6:21 | comment | added | R Thiede | Fair enough! It seems that Packbits gives you the best access times (at expense of disk space), whereas Deflate gives you intermediate/slow access times for intermediate/small files. Also, you can test access times more empirically by creating thumbnails of various sizes and timing how long it takes. Example command: "time gdal_translate -outsize <thumbnail dimensions> -of GTiff <compressed image file> <thumbnail file>" | |
| Sep 6, 2011 at 19:22 | comment | added | matt wilkie | +1 for the linked article, but the important info is offsite and will be lost to us if that page ever goes down or moves. I suggest giving a summary conclusion of the article so that in the event the page is not available, even momentarily, readers have something to work with for future research and thinking. Thanks! | |
