From pretty maps to decisions: designing useful GIS

Alva GeospatialDecember 9, 2024

Geospatial work has a seductive failure mode: the map looks impressive, everyone nods, and nothing changes. A useful map is one that ends an argument or triggers a decision.

Start from the decision

We work backwards from the choice the user needs to make — where to build, who to target, what to monitor — and design the layers and interactions around that, ruthlessly cutting the rest.

If a layer doesn't change a decision, it's noise.

Performance is a feature

Vector tiles, smart aggregation and progressive loading keep the map fast even with millions of features — because a tool people wait on is a tool people abandon.

Start a project

Let's build something that lasts.

Tell us about the system you need — and the team you want running it. We'll show you what's possible.
