ThinkGeo.Gdal.Dependency.Windows 15.0.0-beta002

ThinkGeo.Gdal.Dependency.Windows

A wrapper of GDAL 3.11.3 native DLLs for Windows. This is a foundational dependency for various ThinkGeo packages and is not intended to be referenced directly by application projects.

GDAL is a translator library for raster and vector geospatial data formats, released under an X/MIT-style open source license by the Open Source Geospatial Foundation. As a library, it presents a single raster abstract data model and a single vector abstract data model to the calling application for all supported formats.

Supported platforms

• Architectures: Windows x64, Windows x86
• Minimum OS: Windows 10 / Windows Server 2016 (aligned with the Microsoft Visual C++ 2015–2022 Runtime requirements pulled in via ThinkGeo.Dependency.MicrosoftVisualCRunTime140)
• 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 build/*.targets 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 specifies --runtime win-x64 (or win-x86) on dotnet publish.

What's inside

The package contains GDAL itself plus the third-party libraries GDAL depends on (PROJ, GEOS, SQLite, libcurl, libxml2, OpenSSL 3, HDF4, HDF5, netCDF, cfitsio, libpng, libpq, MySQL Connector, etc.) and a number of optional format plugins (gdal_ECW_JP2ECW, gdal_FITS, gdal_HDF4, gdal_HDF5, gdal_KEA, gdal_MrSID, gdal_PDF, gdal_netCDF, …).

The native binaries are sourced from gisinternals.com (Tamas Szekeres' GDAL build distribution).

Licensing notice — please read

This package is a redistribution of binaries from many upstream projects under different licenses. See the bundled LICENSE.txt for the full breakdown of every license family represented in the package.

A few of the plugins ship under a vendor read-only SDK license rather than an open-source license:

• gdal_ECW_JP2ECW.dll / NCSEcw.dll — Hexagon (formerly ERDAS) ECW/JP2 SDK. Free for read/decode use; encoding and certain commercial server scenarios require a paid license from Hexagon.
• gdal_MrSID.dll / lti_dsdk_9.5.dll / lti_lidar_dsdk_1.1.dll — Extensis (formerly LizardTech) MrSID and Lidar / MG4 Decode SDKs. Free for decode use; encoding requires the commercial GeoExpress product.

ThinkGeo's GDAL integration uses only read/decode functionality, which is covered by the vendors' free SDK licenses. If your application invokes any write or encode operations with these formats, please review the current vendor terms to ensure your deployment is covered.

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.
