Outstanding Issues
In gdal/data we have several coordinate system dictionary files derived in one fashion or another from other source (via translation scripts):


 * gdal/data/cubewerx_extra.wkt: derived from definitions distributed by Cubewerx, rights unclear. TO_RESOLVE (emailed Edric)
 * gdal/data/ecw_cs.dat: Derived via much processing from ERMapper GDT definitions, rights unclear. TO_RESOLVE
 * gdal/data/esri_extra.wkt: Derived with some processing from projections definitions in ArcGIS, rights unclear. TO_RESOLVE

Also two data files - one a seed (template) used when creating DGN files, and one a list of Canadian mapsheet names used by the DTED writer:


 * gdal/data/seed_2d.dgn, seed_3d.dgn: Exact source of these files is unclear. TO_RESOLVE
 * gdal/data/NTS-50kindex.csv: Provided by Matt Wilkie, derived from NRCan dataset, rights unclear. TO_RESOLVE

Discovered that the gdal_merge.py script is accidentally distributed under LGPL instead of MIT/X license:


 * gdal/swig/python/scripts/gdal_merge.py: copyright held by Atlantis, under LGPL. TO_RESOLVE

Noted some concern about the license terms of libgeotiff:


 * Contains copy of libgeotiff, license terms not made clear. TO_RESOLVE (Emailed Niles about using MIT/X license for his libgeotiff code).
 * gdal/frmts/gtiff/geoextra.c: Derived by public domain contribution to libgeotiff from PCI but the terms are not clear. (this also affects libgeotiff) TO_RESOLVE  Email send to Dave Stanley to allow relicensing under MIT/X license.

Included Libraries

 * zlib: gdal/frmts/zlib
 * libtiff: gdal/frmts/gtiff/libtiff
 * libgeotiff: gdal/frmts/gtiff/libgeotiff
 * libjpeg: gdal/frmts/jpeg/libjpeg
 * libpng: gdal/frmts/png/libpng
 * libgif/libungif: gdal/frmts/gif/libungif
 * libcsf: gdal/frmts/pcraster/libcsf
 * hdfeoslib: gdal/frmts/hdf4/hdf-eos

Non-free Libraries
Note: all the following are build options, not required.


 * Oracle OCI for OCI OGR driver.
 * ESRI SDE for SDE OGR Driver.
 * ECW SDK for ECW/JP2ECW GDAL driver (close to free now I think).
 * Kakadu for JP2KAK GDAL driver.
 * MrSID SDK for MrSID/JP2MrSID driver.
 * DWGdirect library for DWG writing.

gdal/port

 * Various contributors including Daniel Morissette, Andrey Kiselev, Frank Warmerdam and Mateusz Loskot.
 * cpl_strtod.cpp is derived from public domain source (properly labelled).

gdal/gcore

 * Various contributed, but mostly FrankW.
 * All copyright held by FrankW.
 * Version.rc contributed without copyright notice by Martin Daly, clarification requested. Martin explicitly agreed by email, notice applied, all ok.

gdal/alg

 * contour.cpp: Joint copyright between FrankW and ACT.
 * gdal_crs.c: derived from old GRASS/UMichigan code also under MIT/X license, properly noted in headers.
 * gdalmediancut.cpp: derived from libtiff tiffmedian.c utility under a GDAL compatible license. Properly noted in headers.
 * gdalrasterize.cpp: Derived from OpenEV code. Relicensed from LGPL to MIT/X by explicit grant from copyright holder (Frank Warmerdam).
 * gvgcpfit.c: Believed to be derived from Numerical Recipes in C. It has not been used for some time, but was still in the CVS repository.  I have now removed it.
 * llrasterize.c: Derived from GD which has compatible MIT/X license. Properly noted in header.
 * thinplatespline.cpp: Contributed by VIZRT Inc., Relicensed to MIT/X with their explicit permission as noted in the header.

gdal/bridge

 * All FrankW, no issues of note.

gdal/data

 * Contains various data files without copyright messages embedded.
 * cubewerx_extra.wkt: derived from definitions distributed by Cubewerx, rights unclear. TO_RESOLVE (emailed Edric)
 * ecw_cs.dat: Derived via much processing from ERMapper GDT definitions, rights unclear. TO_RESOLVE
 * esri_extra.wkt: Derived with some processing from projections definitions in ArcGIS, rights unclear. TO_RESOLVE
 * ellipsoid.csv, gcs.csv, gdal_datum.csv, pcs.csv, prime_meridian.csv, projop_wparm.csv, unit_of_measure.csv: Derived from EPSG. Modifications to EPSG data violate the EPSG use agreement (if we are to still attribute it to EPSG) so I have segregated changes into override files (ie. gcs.override.csv).
 * seed_2d.dgn, seed_3d.dgn: Exact source of these files is unclear. TO_RESOLVE
 * NTS-50kindex.csv: Provided by Matt Wilkie, derived from NRCan dataset, rights unclear. TO_RESOLVE

gdal/apps

 * gdal_contour.cpp: copyright held by ACT.
 * gdaltindex.cpp: copyright held by DM Solutions.
 * gdalwarp.cpp, gdalwarpsimple.cpp: copyright held by i-cubed.

gdal/debian

 * copyright somewhat unclear, not actually part of software.

gdal/dist_docs

 * All written by me, not used any more.

gdal/doc

 * no copyright messages in .dox files.
 * ERMapper logo used with permissions.
 * "ru" subdirectory (Russian translations) by Andrey Kiselev.

gdal/pymod

 * gdal_merge.py: copyright held by Atlantis, under LGPL. TO_RESOLVE
 * gdal2xyz.py: copyright me, under LGPL - relicensed MIT/X.
 * gdal_wrap.c: Generated with SWIG under very permissive license (noted in file).
 * Scripts mostly by me, all ok.

gdal/pymod/samples

 * gdal_vrtmerge.py: Under LGPL (derived from gdal_merge.py), several contributors.
 * histrep.py: corrected copyright message (Atlantis to FrankW), change license to MIT/X.

gdal/wince

 * all written by Mateusz Loskot.

gdal/vb6

 * all written by FrankW, clean.
