Histórico de versões

Gerado do changelog de gisbr/metadata.txt — o mesmo texto publicado no repositório oficial do QGIS (em inglês).

1.2.1

  • Fixed: Census (censobr) tables could fail to load, or join zero tracts, when the pyarrow backend filtered a code column stored as floating point (state/municipality filter by code now works on double columns).

1.2.0

  • Fixed: the GisBR toolbar button could end up hidden in the toolbar overflow menu (seen on Wayland); the toolbar layout is now recomputed after the button style changes.
  • The Macroregion (Large Region) extent was replaced by Health macroregion (Ministry of Health), filtered by state, with the official municipality composition from the DATASUS territorial base (June 2026, 121 macroregions).
  • DNIT, state DER (MG, PR, GO) and railway (MInfra, IBGE BC250) layers are now built as routable networks (links, nodes, problems), with automatic geometry fixes (endpoint snapping, T-junction split, coincident segment merge) and the remaining issues flagged.
  • Fixed: two road ends meeting the same point of another road, or several roads sharing an end near it, could leave one of them disconnected from the network; they now all join a single node.
  • Planned or non-existent segments (DNIT/DER "PLA", planned/under-study railways) are no longer loaded; they go to a "removed" layer.
  • Federal highways repeated in state DER layers are removed from the state layer when the overlap with the DNIT layer is confirmed by geometry and attributes.

1.1.0

  • New diagnostic extents: Microregion, Mesoregion, State and Macroregion (Grande Região) modes, complementing the existing Municipality and Metropolitan Region (RM) options.
  • Embedded official IBGE regional division composition data (extracted on 2026-09-30) mapping all 5,570+ Brazilian municipalities to their respective microregions, mesoregions, and macroregions.
  • Scale-based source disabling: heavy layers (such as Overpass OSM networks and POIs, SICAR cadastral parcels, dense hydrography, and high-resolution rasters) are automatically disabled at state and macroregion scales to prevent memory exhaustion and request timeouts.
  • New official state SDI data sources by UF: Minas Gerais (Sisema-MG: urbanized areas, state and municipal conservation units, wastewater treatment plants [ETE], water usage permits, erosion risk), Goiás (Siga-GO: road network, landfills, Saneago water catchments, state conservation units, landslide susceptibility), São Paulo (DataGeo-SP: flood risk areas), Distrito Federal (IDE-DF: PDOT zoning and macrozoning, administrative regions, public schools), Rio Grande do Sul (SEDUR-RS: urbanized areas and flood/landslide susceptibility for the Taquari Valley), and Paraná (IAT GeoPR: state conservation units and DER state roads).
  • Metropolitan Region mode now loads the OSM road network (links, nodes, problems) from the pre-built gisbr_base release osm-20260929, covering all 84 RMs, with sha256 check and disk cache; OSM POIs remain municipality-only.

1.0.1

  • Fix: Metropolitan Region mode now clips bbox-filtered sources (DNIT, SGB, ANA, schools, neighbourhoods) by the RM boundary; previously they failed with "could not get the clipping polygon".

1.0.0

  • New extent selector: choose between single Municipality or Metropolitan Region (RM) mode in the diagnostic panel.
  • Embedded official IBGE metropolitan composition data (extracted on 2026-09-20) covering the 84 state-instituted metropolitan regions in Brazil (RIDEs are not part of this catalog).
  • Added boundary layer rm_ containing individual municipality polygons for the selected metropolitan region.
  • Note: OSM network and POI sources remain scoped to the target municipality in RM mode to keep query performance fast and light.

0.12.0

  • The OSM road network verification and layers are now built for ONE network per run, vehicle by default, instead of running vehicle and pedestrian every time; this also halves the cost of the geometric verification step.
  • Dead ends (ponta_solta) are no longer listed in osm_problemas by default, since a dead end is normal, not an error; the count of skipped dead ends is reported in the log instead of being silently dropped.
  • One-way traps (mao_unica_sem_saida/mao_unica_borda) now produce one point per trap (group of nodes), not one per node.
  • New REDE (vehicle/pedestrian) and PONTAS_SOLTAS parameters on the gisbr:osm_network Processing algorithm.
  • Removed the componente_pe/grau_pe fields from osm_links/osm_nodes; componente/grau are now generic, for whichever network ran.

0.11.0

  • The OSM road network is now built from the real OSM topology: ways are split into arcs at shared node_ids, so junctions in the middle of a way are no longer lost; the osm_links/osm_nodes schema changed accordingly (arc_id, from_node/to_node, component, degree).
  • New osm_problemas_ layer with a connectivity check: types ilha, ilha_borda, ponta_quase_conectada, ponta_solta, mao_unica_sem_saida, mao_unica_borda and cruzamento_sem_no, each with a severity and the network it belongs to.
  • The vehicle network is now separated from the pedestrian network, and highway types that are not real links (construction, platform, busway, area=yes, etc.) are discarded.
  • New link attributes for transport modelling: maxspeed, velocidade_kmh, comprimento_m.
  • New gisbr:osm_network Processing algorithm (LINKS/NODES/PROBLEMAS outputs), so other plugins can consume the road network via processing.run().
  • The road network now loads in a background QgsTask: progress bar, working Cancel button, QGIS no longer freezes during the download.
  • Municipal clipping now keeps whole arcs that cross the boundary (instead of native:clip), to preserve from_node/to_node.

0.10.0

  • New 9th diagnostic axis (Agriculture & Livestock) featuring IBGE Agregados v3 data (PAM temporary and permanent crops, and Census of Agriculture 2017).
  • MapBiomas Brasil Collection 9 land cover and land use raster integration via Cloud Optimized GeoTIFF (COG).
  • ANM/SIGMINE mining claims broken down by process phase via remote ZIP extraction.

0.9.2

  • The plugin is now called GISBR everywhere in the interface: the toolbar button tooltip and the Plugins menu entry show GISBR instead of the full diagnostic name, the dock panel title is just GISBR, and the Processing provider is listed as GISBR.

0.9.1

  • The toolbar button now shows the GisBR icon with a short GisBR label instead of the full algorithm name; the complete name is kept in the Plugins menu and in the button tooltip.

0.9.0

  • Diagnostic panel reorganised into five tabs (Location, Sources, Census, Output, Log); the Load button now sits below the tabs and is always visible, the panel switches to the Log tab when a load starts, and the Census tab is only enabled when the census tracts source is selected. Panel labels translated to Brazilian Portuguese.

0.8.0

  • New option in the diagnostic panel: attach censobr Census tables to the census tracts layer, so the GeoPackage layer already carries the Census variables. The tract geometry year follows the selected Census year (2000, 2010, 2022); the censobr table is filtered by municipality before the layer is built; the join core is now shared with the join_censo algorithm.

0.7.2

  • Fix: POI loading issue where QgsGeos.contains received a QgsPointXY.

0.7.1

  • Fixes for Overpass data sources (osm_roads and osm_pois): transport timeout enforcement, HTTP and server error response detection, fallback mirror rotation, and strict validation of cached response payload.

0.7.0

  • New OpenStreetMap POI engine (source osm_pois, Urban axis): downloads buildings, amenities and station-like POIs for the selected municipality via Overpass, using the same POI predicate as osm2gmns, and writes two GeoPackage layers (osm_pois_<code>, points, and osm_pois_area_<code>, footprints) with area in m2/ft2 and centroid-based municipal clipping.
  • New gisbr:export_poi_gmns Processing algorithm exporting the POI layer as a poi.csv in the exact osm2gmns/grid2demand column layout.

0.6.0

  • New local-file protocol for official datasets that sit behind a personal gov.br login: instead of a network endpoint, the source reads a file the user downloaded manually, resolves it by pattern from the manual downloads folder, and follows the standard pipeline (clip to the municipality polygon, GeoPackage, skip-if-exists). Missing file skips with guidance instead of failing.
  • Added the INCRA/SIGEF certified parcels source (administrative axis) — the INCRA export service requires a gov.br login, so it uses the new protocol; the plugin never asks for or stores credentials.
  • New "Manual downloads folder" selector in the diagnostic panel.

0.5.0

  • New data sources in the Master Plan diagnostic panel, all public federal services: geological risk sectors (SGB/CPRM), mining claims (ANM/SIGMINE), groundwater wells (SIAGAS), IBGE BC250 2025 layers (roads, railways, drainage, water bodies, densely built-up areas), IBGE urbanised areas (2019) and subnormal agglomerations (2010), and the IBGE BDIA physical environment set (soil, geology, geomorphology, vegetation).
  • Truncated downloads are no longer silent: when a service returns fewer features than matched the filter (WFS numberMatched) or stops at its record limit (ArcGIS maxRecordCount), the log shows a warning and the layer keeps a "truncado" custom property.
  • Server errors returned with HTTP 200 (ArcGIS error bodies and OGC ExceptionReport documents) are now reported with the code and message sent by the server, instead of a generic failure to open the layer.

0.4.3

  • Fix: two error handlers discarded their exception silently. Failing to remove the cached metadata file when refreshing the catalog, and failing to read the local Overpass cache while falling back to it, are now reported with the underlying cause instead of being swallowed.
  • No functional change: the 0.4.2 SSL fix is unchanged and ships here.

0.4.2

  • Fix (SSL on freshly installed Windows/OSGeo4W): downloads failed with "unable to find issuer certificate" because the bundled CA material only covered the IPEA server and was only injected in the geobr downloader. The plugin now ships the self-signed roots used by the GitHub mirror, SICAR, ANA/SNIRH, INDE, SGB, IBAMA, Overpass and the satellite basemap.
  • The certificate injection moved to a single module (core/ssl_support.py) and is now applied to the WFS, ArcGIS REST and Overpass connectors, plus the default SSL configuration used by the XYZ basemap.
  • Certificates are only added as trust anchors; no verification setting is ever relaxed.
  • Network failures now report the host and the underlying error instead of a generic message.

0.4.1

  • Fix (QGIS 4.x / Qt6): the cache directory lookup used the unscoped QStandardPaths.CacheLocation enum, which raises on PyQt6 and made the municipality list fail with "geobr catalog unavailable". The enum is now scoped, and the same fix was applied to the Overpass network error check.
  • The catalog error message now appends the real underlying exception instead of only showing the generic connection hint.
  • The metadata cache path is resolved defensively, so a cache failure falls back to the bundled offline CSV instead of aborting.
  • Declares supportsQt6 so Qt6 builds of QGIS offer the plugin.

0.4.0

  • Added explicit QGIS 4.x compatibility

0.3.2

  • New: municipal OSM road network via Overpass — links + nodes topology, persisted to the municipality GeoPackage, with the same skip-if-exists behavior as the WFS/ArcGIS sources.
  • Robust error handling for Overpass fetches (network errors, invalid JSON responses, per-source timeout honored).
  • Fix: SSL certificate failure when loading IPEA metadata on Windows, with a safe fallback.
  • First non-experimental release.

0.3.1

  • Packaging: exclude the scratch/ research scripts from the published zip (they used urllib/ssl/xml and were flagged by the repository security scan). No change to plugin behavior.

0.3.0

  • Master Plan diagnostic: dock panel (state -> municipality) that loads official layers by axis into a local GeoPackage.
  • New connectors: WFS (CQL_FILTER) and ArcGIS REST (where=), plus an Esri World Imagery satellite basemap.
  • 29-source declarative catalog across 8 axes; server-side filter by municipality with client-side clip to the municipality polygon.

0.2.0

  • Phase 2: Parquet backend (geobr v2.0.0) with 28 read_*_v2 algorithms.
  • censobr integration: join_censo joins geobr census tracts with census tables.
  • Parquet read via the GDAL driver or a pyarrow fallback (driver-independent).
  • 55 algorithms total (26 v1 + 28 v2 + join_censo).

0.1.0

  • Initial release (Phase 1): Processing provider with the legacy GPKG v1.7.0 backend.
  • read_country, read_region, read_state, read_municipality, read_census_tract, read_weighting_area, read_metro_area, read_biomes and more.
  • On-disk cache and mirror fallback (IPEA -> GitHub).
  • Fully PyQGIS + stdlib, no external dependencies.
