Geoid undulation and normal height via IBGE's hgeoHNOR2020 grid (BRAZIL). Automatic offline download (~2 MB), bilinear interpolation, CSV and 3D DXF export.
About
Baixa automaticamente a grade hgeoHNOR2020 do IBGE (arquivo .GGF, ~2 MB) e armazena localmente. Para cada ponto da camada de entrada, aplica interpolação bilinear sobre a grade para obter a ondulação geoidal (N) e a altitude normal (h - N). Exporta CSV enriquecido e DXF 3D. Funciona também como script standalone fora do QGIS.
