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_<id> 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_<code> 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.
