💡 Tip: after uploading, use the Data Editor to add a new column — for example, notes from a field visit — then download your updated CSV.

📖 Guides

Why no detailed guides yet? Geo Mapper is under active development. Detailed written guides would quickly become out of date and cause confusion as features change. The best way to learn is to experiment — upload one of the sample datasets above and explore the Control Panel.

Guides will be added here once the feature set has stabilised.
