Sponsors & Credits¶
Infrastructure Mapper is open source under the MIT license. The schema, tooling, and documentation you're reading exist because of the time and funding of the people and organisations below.
Maintainer¶
Tim Sutton (@timlinux) — project lead, schema design, tooling, and documentation.
Backed by Kartoza¶
This project is developed and supported by Kartoza, a free and open source GIS consultancy based in South Africa with a global remit. Kartoza's day-to-day field work informs every domain in the schema — from rural electrification capture to conservation infrastructure surveys.
If you'd like a custom field-mapping schema, QGIS or QField integration, or training on this project, get in touch: info@kartoza.com.
Sustainable funding¶
Maintaining the schema, tooling, docs, and CI infrastructure takes ongoing time. If Infrastructure Mapper saves you or your organisation work, please consider supporting it:
-
GitHub Sponsors
Recurring or one-off monthly tiers. The most direct way to fund ongoing maintenance.
-
Ko-fi
One-off "buy me a coffee" support. Lower friction than a Sponsors tier.
-
Hire Kartoza
Need custom work that's beyond the scope of this schema? Kartoza takes commercial engagements that keep the open source side funded.
Contributors¶
A full list of contributors lives on the GitHub contributors page. Every issue reporter, PR reviewer, and field tester is part of why this project keeps shipping.
If you've contributed and aren't credited where you'd expect to be, please open an issue — the omission is unintentional.
Tooling we stand on¶
Infrastructure Mapper is composed of open-source giants:
- PostgreSQL + PostGIS — the canonical store.
- GDAL/OGR — the GeoPackage build pipeline.
- QGIS — the desktop and field map client.
- QField and Mergin Maps — field capture.
- Nix + Determinate Systems — the reproducible dev shell and CI.
- mkdocs-material — this documentation site.
- sqlfluff, black, ruff, shfmt, shellcheck, markdownlint, cspell, reuse — the quality gates.
Without these projects, Infrastructure Mapper wouldn't exist. Please sponsor them too if you can.
