ThinkGeo.Gdal.Dependency.Windows
================================
This NuGet package redistributes prebuilt GDAL 3.11.3 native binaries and
the third-party libraries that GDAL depends on, sourced from the GDAL
build artifacts produced by gisinternals.com (Copyright (c) Tamas
Szekeres). The packaging metadata, MSBuild .targets, and
ThinkGeo-authored content are released under the MIT License.
The redistributed native DLLs come from many upstream projects that are
each licensed under their own terms. By using this package you agree to
comply with all of the licenses below for any DLLs you actually load at
runtime.

respective project. The license summary above is informational; the
authoritative terms are those distributed with each upstream project.

4. Vendor-distributed SDK plugins
----------------------------------------------------------------------
The following DLLs in this package are NOT open source. They are
vendor-distributed SDKs included so that GDAL can dynamically load
them as raster format plugins. By using any of these plugins you
agree to the corresponding vendor's end-user license terms linked
below.
- gdal_ECW_JP2ECW.dll, NCSEcw.dll (NCSEcw.dll is "ECWJP2 SDK 5.5")
Hexagon (formerly ERDAS) ECW/JP2 SDK v5.x.
Decoding ECW/JP2 imagery on Desktop is free of charge under
Hexagon's terms; this is the use covered by ThinkGeo's
integration. The bundled binary is a full read/write build
and is also capable of compressing/encoding ECW imagery, but
encoding is gated at runtime — it requires an OEM license
key purchased from Hexagon, supplied to GDAL via the
ECW_ENCODE_KEY and ECW_ENCODE_COMPANY environment variables.
Server-side use of v5.x SDK and unlimited-size mobile decode
also require a paid Hexagon license.

See also: https://gdal.org/en/stable/drivers/raster/ecw.html
- gdal_MrSID.dll, lti_dsdk_9.5.dll, lti_lidar_dsdk_1.1.dll
Extensis (formerly LizardTech) MrSID Decode SDK (DSDK) and
Lidar / MG4 Decode SDK. Free for decode use under Extensis's
developer terms.
These bundled binaries are the Decode SDK build and are
decode-only by design — they cannot encode/write MrSID,
MG3, MG4, or related LiDAR formats regardless of the
license held. Producing those formats requires a different
gdal_MrSID.dll built against Extensis's Encode SDK (ESDK)
or use of the commercial GeoExpress product.

See also: https://gdal.org/en/stable/drivers/raster/mrsid.html
If your application invokes any write/encode operations with these
formats, confirm that your deployment is covered by the vendor's
terms (and, in the ECW case, that you hold a valid OEM encode key).
