cnefetools: Access and Analysis of Brazilian CNEFE Address Data
Download, cache and read municipality-level address data from the
Cadastro Nacional de Enderecos para Fins Estatisticos (CNEFE) of the 2022
Brazilian Census, published by the Instituto Brasileiro de Geografia e
Estatistica (IBGE)
<https://ftp.ibge.gov.br/Cadastro_Nacional_de_Enderecos_para_Fins_Estatisticos/>.
Beyond data access, provides spatial aggregation of addresses, computation
of land-use mix indices, and dasymetric interpolation of census tract
variables using CNEFE dwelling points as ancillary data. Results can be
produced on 'H3' hexagonal grids or user-supplied polygons, and heavy
operations leverage a 'DuckDB' backend with extensions for fast,
in-process execution.
