Integrated Geospatial Database of Land Cover, Building Morphology, Local Climate Zones, and ENVI-met Material Parameters for Viçosa, Brazil

Description

This repository contains an integrated geospatial database for the municipality of Viçosa, Minas Gerais, Brazil, developed to represent land cover, urban surfaces, and building morphology. The dataset is designed for use in Geographic Information Systems (GIS) and urban microclimate modeling workflows, with direct support for model parameterization in ENVI-met.

The database harmonizes and integrates multiple public and institutional data sources, including the Brazilian National Water and Sanitation Agency (ANA), municipal Master Plan cartographic annexes, CBERS-4A satellite imagery from the National Institute for Space Research (INPE), MapBiomas Collection 4, Google Open Buildings, the Local Climate Zone (LCZ) Generator, and the Brazilian Institute of Geography and Statistics (IBGE) 2022 Urbanized Areas dataset. Heterogeneous thematic classification schemes are converted into a standardized, high-resolution spatial representation.

Dataset highlights

  • Multi-source harmonization: Spatially explicit and standardized representation of major urban and rural surface types on a regular metric grid with a spatial resolution of 5 m (SIRGAS 2000 / UTM zone 23S, EPSG:31983).

  • Ready for microclimate modeling: Integrates horizontal surface composition with three-dimensional building morphology and building material parameters to support input preparation for ENVI-met and other environmental models.

  • LCZ-enriched building attributes: The building vector dataset associates Google Open Buildings footprints with Local Climate Zones, characteristic building heights, and identifiers for ENVI-met construction materials and thermophysical properties.

  • Traceability and reproducibility: Includes lookup tables and automated Python scripts documenting the reclassification and priority-based data fusion procedures.

  • Multi-scale coverage: Includes products covering the entire municipality (299.538 km²) and a spatial subset restricted to the IBGE 2022 Urbanized Areas (19.272 km²).

Land cover classification dictionary

The harmonized classification scheme comprises the following categories:

Code Class Surface group Description
0 NoData Unclassified Cells outside the municipal boundary or outside the urban mask.
1 Grass Vegetation Low herbaceous vegetation and short grassland or pasture.
2 Soil Permeable surface Bare soil, agricultural land, and predominantly exposed surfaces.
3 Impervious surface Built surface Urban pavements, squares, and non-road impervious areas.
5 Tree canopy Vegetation Forest formations, urban trees, and medium- to tall vegetation.
6 Road Infrastructure Urban road networks and highways.
7 Water Water surface Mapped rivers, lakes, reservoirs, and other water bodies.
8 Buildings Built surface Spatial footprints of urban and rural buildings.

Building morphology and material parameterization

The building layer (edificacoes_LCZ.gpkg) was derived from Google Open Buildings and enriched with Local Climate Zone classifications. Each building was assigned an estimated height and a construction material profile compatible with ENVI-met.

1. LCZ-based building height assignment

The following building heights were assigned according to LCZ class:

  • LCZ 1 and 4: 30.0 m

  • LCZ 2 and 5: 17.5 m

  • LCZ 11: 15.0 m

  • LCZ 10: 10.0 m

  • LCZ 12: 9.0 m

  • LCZ 3, 6, 8, and 9: 6.5 m

  • LCZ 7, 13, 14, 15, 16, and 17: 3.0 m

These values represent assigned characteristic heights based on LCZ classes rather than individually measured heights for every building.

2. ENVI-met material grouping

The building material lookup table includes the following material groups and properties:

Material ID Associated LCZ classes Thickness (m) Absorption Reflection Emissivity
LCZ002 LCZ 1–2 0.15 0.85 0.15 0.94
LCZ005 LCZ 4–5 0.15 0.80 0.20 0.94
LCZ00A LCZ 10–11 0.15 0.85 0.15 0.94
LCZ39F LCZ 3, 6–9, and 12–16 0.15 0.80 0.20 0.94

The assigned material properties are intended to support consistent model parameterization. Users should consult the lookup tables and technical documentation before modifying these values or applying them to other urban contexts.

Integrated data sources and processing functions

Provider or source Original data Role in processing
Brazilian National Water and Sanitation Agency (ANA) Land use and land cover data Primary land cover information and thematic reclassification.

Recommended applications

This database can support:

  • Urban microclimate modeling: Preparation of three-dimensional simulation domains and surface inputs for ENVI-met.

  • Urban heat island studies: Analysis of relationships between built morphology, building envelope materials, and urban thermal patterns.

  • Outdoor thermal comfort assessments: Evaluation of indices such as Physiological Equivalent Temperature (PET) and Universal Thermal Climate Index (UTCI) at neighborhood or municipal scales.

  • Urban planning and climate resilience: Environmental assessments supporting Master Plan development and simulations of urban expansion scenarios.

  • GIS-based urban analysis: Spatial assessment of land cover composition, building footprints, and LCZ-associated morphology.

Coordinate reference system and spatial resolution

  • Coordinate reference system: SIRGAS 2000 / UTM zone 23S.

  • EPSG code: 31983.

  • Raster resolution: 5 m × 5 m.

  • Pixel area: 25 m².

  • Geographic coverage: Municipality of Viçosa, Minas Gerais, Brazil, including a dedicated subset corresponding to the IBGE 2022 Urbanized Areas.

Data limitations and considerations

Building heights are assigned from LCZ-based characteristic values and should not be interpreted as individually measured building heights. Similarly, material identifiers and thermophysical properties represent standardized modeling assumptions rather than verified measurements of every building's actual construction materials.

The spatial accuracy and thematic detail of the integrated products depend on the original datasets, their dates, spatial resolutions, and classification procedures. Users should consult the lookup tables, scripts, and accompanying documentation when adapting the database to other areas or modeling conditions.

The raster products contain NoData cells outside their respective valid spatial extents. In particular, urbanized_area_2022.tif is restricted to the IBGE 2022 Urbanized Areas mask and therefore has a high proportion of NoData cells relative to its rectangular raster dimensions.
