Re: [gdal-dev] Twenty years of GDAL !

[Markus Neteler]

Frank, Even, all  GDAL devs,

a big "thank you" from the GRASS GIS community!

Frank, your initial contribution was r.in.gdal on Sep 26, 2000:
https://trac.osgeo.org/grass/changeset/1688

r.in.gdal got released the first time with GRASS GIS 5.0:
https://grass.osgeo.org/announces/announce_grass50beta10.html

... 18 years ago!

Thanks again for all your efforts to develop GDAL!

Markus

Even,

Wow, 20 years!  Thanks for pointing out this milestone.

It is a huge pleasure to know that:
 - it has been a core technology supporting so many other software packages and 
projects
 - it has been a project that lots of people have felt comfortable contributing 
to

GDAL is the core of our data processing pipeline at Planet where we have a 
number of esoteric internal GDAL drivers, so I continue to use it every day. 

Special thanks to Even who's outsize contribution has kept the project healthy 
and progressing as I focused on other activities. 

Best regards,
Frank

Happy Birthday GDAL! GDAL has been a large chunk of my professional career.
I am still using the library and tools every day.

Thank you Frank, Even and the entire GDAL community.

Hi,

I used your command for one of our orthophoto .jp2 files with these drivers

  gdalinfo --formats|find "JP2"
  JP2ECW -raster,vector- (rov): ERDAS JPEG2000 (SDK 5.3)
  JP2MrSID -raster- (rov): MrSID JPEG2000
  JP2OpenJPEG -raster,vector- (rwv): JPEG-2000 driver based on OpenJPEG
library

The resulting half-dimensioned GeoTIFF is good with all drivers. Without
having a recent Kakadu driver available I fear that I can't test anything
more.
If your build suppors debug messages you can have a new try by adding
"--debug on" into your gdal_translate command.

Re: [gdal-dev] Creating external overviews for JP2 files?

[Alessandro Parma]

Thanks for your reply,

My bad, probably copy-pasting mistake. I've re-run the commands:

Just to be sure I exported the GDAL_SKIP env var as well:

export GDAL_SKIP=JP2OpenJPEG
gdalinfo --formats
...
  ERS -raster- (rw+v): ERMapper .ers Labelled
  JP2KAK -raster,vector- (rwv): JPEG-2000 (based on Kakadu *v7.10.4*)
  JPIPKAK -raster- (ro): JPIP (based on Kakadu)
  L1B -raster- (rovs): NOAA Polar Orbiter Level 1b Data Set
...
(No JP2OpenJPEG, by the way, I am using Kakadu 7.10.4)

Looks like gdal_translate is producing a 0-filled raster:

gdal_translate -outsize 50% 50% -co TILED=YES -co COMPRESS=JPEG -co

Re: [gdal-dev] Twenty years of GDAL !

[Andreas Neumann]

Hi gdal-devs,

Many thanks for your efforts in the past years - it is much appreciated!

Many people don't realize that they use your software (behind the 
scenes) on every work day ...


It is nice to be able to use your drivers and utilities and build 
something on top of it - without restrictions!


Greetings,

Andreas

Actually this is a little known feature of GDAL, but if you create a symbolic 
link, GDALOpen() will read the link name, and open it, even if it is not a 
real file.

ln -s /vsicurl/https://download.osgeo.org/gdal/data/gtiff/utm.tif your.vrt.ovr
gdalinfo your.vrt.ovr

Another more OS portable approach is to
gdal_translate -of VRT /vsicurl/ your.vrt.ovr

Thanks for quick reply. Unfortunately this suggestion will not work for us,
since we want to use an ovr that is located online and it is hard to manage
