See the dramatic volcanic landscape of Tongariro National Park in New Zealand, captured by Landsat 8. Located on the North Island, this region is dominated by Mount Ruapehu, the island’s highest peak. Nearby, Mount Ngauruhoe and Mount Tongariro shape this active volcanic massif, alongside the tranquil Tama Lakes and the striking Blue Lake. 🌋

At the Centre for Geographical Analysis, geospatial analysis goes beyond mapping locations, as it’s about revealing relationships. By connecting patterns in nature and society, we can see how environmental processes and human activity influence one another. These spatial connections turn complex datasets into meaningful insight, supporting stronger research, smarter planning, and more informed decision-making across disciplines.

On this day in 1963, Roger Tomlinson began work on the Canada Geographic Information System (CGIS), one of the world’s first computerised GIS platforms and a direct ancestor of modern geographic information systems.

Your legacy continues to shape how we understand and map our world.
Thank you, Roger.

An aerial view captures swirling sediment patterns in the Gulf of Mexico near the Louisiana coastline. The scene transitions from deep reds to smoky blue-grey tones, creating a calm visual surface that contrasts with the dynamic movement beneath. The abstract formations evoke the appearance of planetary imagery, reminiscent of close-up observations of Jupiter, while revealing the complex natural processes at work in the water below.

At the CGA, every insight begins with a question rooted in place, but it’s precise, reliable data that transforms those questions into meaningful understanding. By applying rigorous, data-driven methods to real-world spatial challenges, we ensure that our research, analysis, and solutions are built on accuracy, credibility, and impact.

Because when data is precise, decisions are stronger and understanding goes deeper.

We’re back and ready for the year ahead!

The CGA offices are officially open, and we’re looking forward to another year of advancing geographic knowledge, collaboration, and impact.

Here’s to a productive and inspiring year ahead.
