2018-12-19 Thread Luke Roth
I know that a number of format-specific options can be set as environment variables so they don't have to be specified on the command line (TIFF_USE_OVR, GTIFF_IGNORE_READ_ERRORS). Is there a way to set defaults for other format-specific dataset creation options (for geotiff, TILED=YES, COMPRESS=L

Another thing that might speed up access is setting the config option GDAL_DISABLE_READDIR_ON_OPEN = TRUE, either as an environment variable or on the command line. That should help with GDAL reading the directory each time it opens a dataset. I have an application which reads one value from each

For any who are interested, I've published a (incomplete, but growing) set of GDAL bindings for the Go language at https://github.com/lukeroth/gdal.go . The bindings cover most of the GDAL C API, the OGR C API is next. More details are available at the Github page. Let me know if you find them use

[gdal-dev] GDAL block cache question

2008-10-08 Thread Luke Roth
Hi everybody, I've been working on writing an image viewer using GDAL, and I'd like to take advantage of the block cache to avoid keeping multiple copies of things in memory where I can. I'm currently using the GetLockedBlockRef() function, which works well, but can sometimes lead to large delays
