ThinkGeo.Gdal.Dependency.Windows 14.5.2

ThinkGeo.Gdal.Dependency.Windows

A wrapper of GDAL 3.11.3 native DLLs for Windows, together with the third-party libraries GDAL depends on (PROJ, GEOS, SQLite, libcurl, OpenSSL 3, HDF4/5, netCDF, etc.) and a number of optional format plugins (gdal_FITS, gdal_HDF4/5, gdal_KEA, gdal_PDF, gdal_netCDF, plus gdal_ECW_JP2ECW and gdal_MrSID under vendor SDK terms). The native binaries are sourced from gisinternals.com (Tamas Szekeres' GDAL build distribution).

This is a foundational dependency for various ThinkGeo packages and is not intended to be referenced directly by application projects.

Supported platforms

• Architectures: Windows x64, Windows x86
• Minimum OS: Windows 10 / Windows Server 2016
• Target frameworks: any project that targets a win-x64 or win-x86 Runtime Identifier, including modern .NET (.NET 6 / 7 / 8 / 9 …) and classic .NET Framework via the bundled MSBuild fallback

The native DLLs are placed under runtimes/win-x64/native/ and runtimes/win-x86/native/, and flow into the application's publish output automatically when the consuming project runs dotnet publish --runtime win-x64 (or --runtime win-x86).

The DLLs also flow into the build output during dotnet build: with no explicit RID they are placed under bin/<config>/<tfm>/runtimes/<rid>/native/ (the .NET runtime resolves them from there at execution time, so F5 / IDE runs work as-is); with an explicit RID, e.g. dotnet build --runtime win-x64, they are placed flat in bin/<config>/<tfm>/<rid>/, the same layout publish produces.

Licensing

GDAL and most of its bundled dependencies are open source, and ThinkGeo's GDAL integration uses only read/decode functionality. The two key caveats:

• The bundled ECW/JP2 plugin (gdal_ECW_JP2ECW.dll, NCSEcw.dll, Hexagon ECW SDK v5.x) is a full read/write build. Decoding is free under Hexagon's terms; encoding is license-gated at runtime via an OEM key passed through the ECW_ENCODE_KEY / ECW_ENCODE_COMPANY environment variables, which you must obtain from Hexagon if needed.
• The bundled MrSID and LiDAR/MG4 plugins (gdal_MrSID.dll, lti_dsdk_9.5.dll, lti_lidar_dsdk_1.1.dll, Extensis DSDK) are decode-only by design — they cannot encode regardless of license.

See the bundled LICENSE.txt for the full per-component breakdown across GDAL, the open-source dependencies, the ECW/MrSID vendor SDKs, and the transitive Microsoft VC++ runtime.

Reporting issues

This package is part of the ThinkGeo product line. Please report issues through ThinkGeo support channels rather than to the upstream GDAL or gisinternals projects.
