Spatial baselines for climate tools: what to expose in the UI
A practical guide to choosing which geospatial assumptions and baseline layers should be visible to decision-makers.
Spatial tools become less useful when important baseline assumptions are hidden behind technical defaults. Decision-makers do not need every GIS detail, but they do need visibility into which layers and baseline choices materially shape interpretation.
A useful baseline is a legible baseline
A good climate dashboard exposes the layers that affect judgment, keeps contextual layers available without clutter, and makes it clear which view is operational versus exploratory.
The practical question is not whether to show more data. It is whether the interface makes the baseline legible enough that users can trust what they are looking at and defend the decisions that follow. For applied geospatial design, sources such as NASA Earthdata can also help teams think carefully about provenance and layer selection.[fn-1]
The wrong baseline does not just distort a chart. It distorts the decision that follows from it.
