Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-0d0c3744b220f265 quantitative
Manaus's municipal property register had not had a full update since 2010.
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The subsecretário da Receita, Armínio Pontes, is quoted directly: "A última atualização desse nível foi realizada em 2010" ("The last update at that level took place in 2010").
Caveat

Claim 2 clm-9d675447bd8cf3b0 quantitative
From late 2019 the finance and IT secretariat SEMEF ran Mapa de Manaus with contractor Topocart
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The contractor's own page states the city began the project at the end of 2019 ("a Prefeitura deu início, no final de 2019, a um grandioso projeto") and names the executing agency as SEMEF ("executado pela Secretaria Municipal de Finanças e Tecnologia da Informação (Semef)"); Topocart is the author of this page, titled 'Topocart executa as etapas finais do Projeto Mapa de Manaus', confirming its role as the survey contractor.

Claim 3 clm-bca40720f00b7490 quantitative
an aircraft flew metric aerial photography with laser profiling over more than 520 km²
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Confirms the technique ("levantamento aerofotogramétrico com perfilamento laser", aerophotogrammetric survey with laser profiling) and the area covered: "No total, a base cartográfica abrangeu mais de 520 km²" ("In total, the cartographic base covered more than 520 km²").

Claim 4 clm-6a3ac125880b317d quantitative
a vehicle drove the streets capturing 360° façade imagery
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The source describes '360° mobile mapping of property façades' ("mapeamento móvel 360º das fachadas dos imóveis"); the city's own account of the same technology calls it 'terrestrial mobile mapping scanning' ("varredura por mapeamento móvel terrestre em 360°"), standard terminology for vehicle-mounted mobile mapping systems.
Caveat
Neither source uses the word 'vehicle' explicitly; 360° terrestrial mobile mapping at this scale is standard vehicle-mounted survey technology, but the sources describe the method rather than the equipment.

Claim 5 clm-00be0a85796d3b5d quantitative
around 70 field teams verified buildings on the ground

snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
"o levantamento cadastral de campo contou com 70 equipes para cadastrar quase 600 mil imóveis" ("the field cadastral survey had 70 teams to register nearly 600,000 properties").

Claim 6 clm-8a2755a4d5f415a4 quantitative
producing a 10 cm-precision orthophoto base
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The source states the cartographic base achieved 10 cm precision: "com uma precisão de 10 cm".
Caveat
The source gives the 10 cm precision figure but never uses the word 'orthophoto' ('ortofoto'/'ortomosaico' do not appear on the page); the orthophoto product is inferred from the aerophotogrammetry-with-laser-profiling method, not stated directly.

Claim 8 clm-ba7c9d7fd7ed2e5f quantitative
By March 2023 some 345,000 of the city's ~601,000 registered properties had been updated
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
A Crítica (dated 2023-03-07) states this year's IPTU billing totalled 601,000 property registrations ("O lançamento do Imposto sobre a Propriedade Predial e Territorial Urbana (IPTU) deste ano somou 601 mil cadastros imobiliários"); the city's own release states roughly 345,000 of these had records updated ("aproximadamente 345 mil imóveis da capital amazonense tiveram seus dados atualizados junto à base do cadastro imobiliário municipal").

Claim 9 clm-0c206a65bb252cd0 quantitative

Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
"também foram inclusos cerca de 10 mil imóveis que ainda não faziam parte da base cadastral imobiliária da prefeitura" ("about 10,000 properties that were not yet part of the city's property cadastre were also included").

Claim 10 clm-db8edb5979a442ee descriptive
The layers now sit on the city's own ArcGIS Enterprise server
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Directly fetched: a live ArcGIS Enterprise 11.5 REST Services Directory hosted by the city, listing about 60 folders including GEOMANAUS, SEMEF, SEMEF_3D, IMPLURB, IMMU, CCC and SEMULSP — municipal-department-named services consistent with 'dozens of departmental services'.
Caveat
The directory confirms the city operates this ArcGIS server, with SEMEF- and GEOMANAUS-named folders among roughly 60 total, but the page does not itself label any layer as the Mapa de Manaus survey output — the link between these folders and this specific project is inferred from SEMEF being the project's executing agency, not stated on the page. Not every one of the roughly 60 folders is confirmed to represent a distinct city department; some may be generic or utility folders.

Claim 11 clm-ac4ea326cc525ae4 quantitative

Claim 13 clm-4d7d15e7dcf861e2 descriptive
Residents told the press their bills had doubled, tripled or quadrupled
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
City councillor Rodrigo Guedes is quoted describing residents' reaction: "Os manauaras foram surpreendidos com valores em dobro, triplo e até quatro vezes o que estava sendo cobrado em 2022" ("Manaus residents were caught off guard by amounts double, triple and even four times what was charged in 2022").
Caveat
The 'doubled, tripled or quadrupled' framing is city councillor Rodrigo Guedes's public characterization of residents' reaction, not a verbatim quote from a resident. The two residents quoted directly in the source describe smaller specific increases — one from R$700 to R$1,200, about 71%.

Claim 16 clm-e64508ca1f2720dc descriptive
the rate had not risen, only the recorded area
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Councillor Rodrigo Guedes states no law was passed changing the IPTU rate or tax base: "não foi aprovada nenhuma lei aqui na CMM que aumente a alíquota ou a base de cálculo do IPTU" ("no law was passed here in the City Council raising the IPTU rate or the tax base") — confirming the increase came from the updated recorded property area, not a rate change.
Caveat
This is a statement by councillor Rodrigo Guedes, not an independent audit of the tax roll — it confirms no rate-changing law was passed, not an independently verified accounting of exactly what changed in every individual case.

Primary evidence, fetched and verified directly: a live ArcGIS Enterprise 11.5 server publishing 59 folders including GEOMANAUS, SEMEF, SEMEF_3D, IMPLURB, IMMU, CCC, SEMULSP and MANAUS_3D_TESTE — the operating geospatial layer the survey fed. Note: the public front end mapademanaus.manaus.am.gov.br returned HTTP 503 to automated requests on 2026-08-10 (twice); a human should confirm the viewer is reachable before sealing.

Known limits of this passport
  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
