GeoDMS

Geographic Data & Model Software (GeoDMS) is a platform for developing Geographic Planning Support Systems. Where fast generic, land-use modelling and routing algorithms are implemented in C++ and exposed through the GeoDMS scripting language.

Downloading and getting started

Recent GeoDMS versions can be downloaded from this repository's release page.

If you are new to GeoDMS, the GeoDMS Academy will guide you through some of the language's basic features. For the complete documentation of GeoDMS, including additional examples, see our wiki or geodms website

Verifying downloads

All GeoDMS installers and packages are signed with the Object Vision B.V. GlobalSign EV Code Signing certificate. Only run or install a package after confirming it carries a valid signature from Object Vision B.V.

Windows

The .exe installer is Authenticode-signed. Windows will show a publisher dialog during installation; confirm the publisher reads Object Vision B.V. before proceeding.

To verify before running:

# PowerShell — should print "Valid" and show O=Object Vision B.V.
Get-AuthenticodeSignature "GeoDms<ver>-Setup-x64-cmake.exe" | Format-List

Or right-click the file → Properties → Digital Signatures → select the signature → Details → confirm the signer is Object Vision B.V.

Linux

Each Linux release includes a SHA-256 checksum file and a CMS/PKCS#7 detached signature (.p7s) signed with the Object Vision B.V. GlobalSign EV Code Signing certificate. Download both alongside the tarball and verify before extracting:

openssl cms -verify -binary -purpose any \
  -in      GeoDms<ver>-linux-x64.tar.gz.sha256.p7s -inform DER \
  -content GeoDms<ver>-linux-x64.tar.gz.sha256 \
  -CAfile  <(curl -fsSL http://secure.globalsign.com/cacert/codesigningrootr45.crt \
             | openssl x509 -inform DER)

sha256sum -c GeoDms<ver>-linux-x64.tar.gz.sha256

For a full explanation of the certificate chain, how to obtain the signing root from alternative sources, and how to inspect the signer identity, see nsi/VERIFY-LINUX.md.

Compilation

Build instructions for GeoDMS can be found at our wiki compilation page or our website. For a technical overview of the GeoDMS software, see readme-dms.MD in the GeoDMS source code root folder, or here
