FOSS4G 2025 logo proposal
FOSS4G 2025 is being held in Aotearoa / New Zealand. I responded to the call for logo design proposals using a recreation of the FOSS4G SoTM Oceania design I submitted – https://iamadamsteer.com/portfolio/foss4g-sotm-oceania-2019-logo/ . This wasn’t successful at the time, however I like it a lot – so decided to refresh it for 2025. The Koru…

Image transects for ecological baselines
This project was undertaken in March 2024, with a briefing to collect geo-tagged imagery and video along specified transects over a shallow lake. These will be used as a condition assessment baseline. The technical challenge was developing repeatable flight paths between specific coordinate pairs. Drone control software often permits this type of flight based on…

Fram Strait
A visualisation of Fram Strait, developed from GEBCO global topography and bathymetry data. The key design problem for this map was rendering bathymetric detail in both very shallow / low relief regions (Barents Sea) and very deep, high relief regions (Arctic Basin). A solution was found using a combination of layering and rendering methods in…

Spatialised logo
Spatialised needed a logo! So I made one. The design principles are detailed here: https://www.spatialised.net/sponsoring-foss4g-sotm-oceania/ A short version is that Spatialised generally focused on geospatial problems with a strong pull toward high resolution topography. The logo is aiming at representing topography and bathymetry, in a fun style which can be adapted easily to many color…

FOSS4G SotM Oceania 2019 logo
An entry to the logo design competition for FOSS4G SotM Oceania 2019. I wrote at the time: “This design is inspired by the Koru, a Maori symbol of strength, growth, nurturing and hope, drawn in turn from the characteristic shape of an unfurling fern frond. The motif of a spiral, or circles-within-circles, is also common…

Mapping static avalanche risk factors
A project to map terrain-based static features which contribute to avalanche occurrence, using popular backcountry ski destinations in New South Wales, Australia. Here the key design problem is how to visualise slope classes using a commonly-seen color scale in snow safety – alongside other relevant terrain features. The technical achievement was developing these datasets from…
