Interactive dashboard for historical land price analysis in Paraná, built from public DERAL data with a full ETL pipeline and geographic layer integration.
DERAL (Paraná's department of rural economy) publishes a monthly land price report as a series of PDFs. Anyone trying to look at the historical series has to parse the PDFs by hand. This dashboard reverses that — it ingests every release, normalises the categories, joins them to territorial polygons, and surfaces the time series with regional filters.
The dashboard is fully open-source on GitHub; the data product is the PDF pipeline plus the React dashboard on top of it.
Scattered PDF reports transformed into a queryable data product with territorial filtering and historical price visualisation.
