The source for the Shapefile C Library is (c) 1998 Frank Warmerdam, and released under the following conditions. The intent is that anyone can do anything with the code, but
|
|
that I do not assume any liability, nor express any warranty for this code.
|
|
|
|
As of Shapelib 1.2.6 the core portions of the library are made available under two possible licenses. The licensee can choose to use the code under either the Library GNU
|
|
Public License (LGPL) described in LICENSE.LGPL or under the following MIT style license. Any files in the Shapelib distribution without explicit copyright license terms
|
|
(such as this documentation, the Makefile and so forth) should be considered to have the following licensing terms. Some auxilary portions of Shapelib, notably some of the
|
|
components in the contrib directory come under slightly different license restrictions. Check the source files that you are actually using for conditions.

Default License Terms
|
|
Copyright (c) 1999, Frank Warmerdam
|
|
|
|
This software is available under the following "MIT Style" license, or at the option of the licensee under the LGPL (see LICENSE.LGPL). This option is discussed in more
|
|
detail in shapelib.html.

Shapelib Modifications
|
|
I am pleased to receive bug fixes, and improvements for Shapelib. Unless the submissions indicate otherwise I will assume that changes submitted to me remain under the the
|
|
above "dual license" terms. If changes are made to the library with the intention that those changes should be protected by the LGPL then I should be informed upon
|
|
submission. Note that I will not generally incorporate changes into the core of Shapelib that are protected under the LGPL as this would effectively limit the whole file and
|
|
distribution to LGPL terms.
|
|
|
|
Opting for LGPL
|
|
For licensee's opting to use Shapelib under LGPL as opposed to the MIT Style license above, and wishing to redistribute the software based on Shapelib, I would ask that all
|
|
"dual license" modules be updated to indicate that only the LGPL (and not the MIT Style license) applies. This action represents opting for the LGPL, and thereafter LGPL
|
|
terms apply to any redistribution and modification of the affected modules.
