Code Reviewed

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.

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

gdal/data

• Contains various data files without copyright messages embedded.
• cubewerx_extra.wkt: derived from definitions distributed by Cubewerx, rights unclear.
• ecw_cs.dat: Derived via much processing from ERMapper GDT definitions, rights unclear.
• esri_extra.wkt: Derived with some processing from projections definitions in ArcGIS, rights unclear.
• ellipsoid.csv, gcs.csv, gdal_datum.csv, pcs.csv, prime_meridian.csv, projop_wparm.csv, unit_of_measure.csv: Derived from EPSG. Redistribution may violate the EPSG "distribute as a whole" requirement.
• seed_2d.dgn, seed_3d.dgn: Exact source of these files is unclear.
• NTS-50kindex.csv: Provided by Matt Wilkie, derived from NRCan dataset, rights unclear.

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.
• gdal_wrap.c: Generated with SWIG under very permissive license (noted in file).
• Scripts mostly by me, all ok.

gdal/pymod/samples

• various contributors, all under proper and compatible copyright headers.

gdal/wince

• copyright held by Taxus
• Added copyright headers in a few file where they were missing.
• all subdirectories checked.

• all subdirectories checked.

TODO

• gdal/*.*
• gdal/frmts
• gdal/ogr
• gdal/swig
• gdal/rfc

Summary

1. Several files in gdal/data are derived from non-free sources, and it is necessary to get permission to redistribute them.
2. The EPSG derived files are arguably not distributed in compliance with their requirements. See direction/permission from EPSG.
