Rockstar
Top expert inGeospatial Technology and Web Mapping
Tom Payne is a Senior Geospatial Developer based in Geneva with 19 years of experience building robust mapping and geospatial systems. He blends front-end polish (contributions to Cesium and OpenLayers) with backend geospatial engineering in Go (authoring go-geom WKB support and database integrations) and practical DevOps automation (chezmoi and goreleaser). At Camptocamp he applies this cross-stack expertise to deliver performant tile, WMS and image-processing solutions, having improved MapProxy image merging and Map/CLI UX in projects like Hubble. An active open-source maintainer, Tom moves fluidly between UI fixes, low-level geometry encoding, and documentation—helping both users and other contributors. Outside code he’s the creator of chezmoi.io and even flies paragliders, showing a taste for elegant tooling and high-altitude perspectives.

Package geom implements efficient geometry types for geospatial applications.
Role in this project:Back-end Developer
Back-end DeveloperContributions:6 releases, 13 reviews, 579 commits in 8 years 11 months
Contributions summary:Tom primarily contributed to the development of the `go-geom` library, a Go package for geospatial applications. They implemented functionality for encoding and decoding geometries in the Well Known Binary (WKB) format, including the creation of types for point, linestring, polygon, multipoint, multilinestring, and multipolygon geometries, implementing functions to handle those types.. The user also worked on the implementation of the Scanner and Valuer interfaces for the database/sql/driver to facilitate easy integration with databases like PostGIS.
