How this atlas is made · What “last verified” means · What “source-checked” means · The full record behind this page

Manaus's municipal property register had not had a full update since 2010. From late 2019 the finance and IT secretariat SEMEF ran Mapa de Manaus with contractor Topocart: an aircraft flew metric aerial photography with laser profiling over more than 520 km², a vehicle drove the streets capturing 360° façade imagery, and around 70 field teams verified buildings on the ground, producing a 10 cm-precision orthophoto base and a catalogue of roughly 600,000 property units. By March 2023 some 345,000 of the city's ~601,000 registered properties had been updated and about 10,000 properties entered the register for the first time. The layers now sit on the city's own ArcGIS Enterprise server.

📊 Impact

SEMEF reports about 345,000 of roughly 601,000 registered properties updated and about 10,000 previously unregistered properties added; the subsecretário da Receita states the last update at that level was in 2010.

🎓 Lesson

Remeasuring a city is a tax event, and Manaus met it as one. Residents told the press their bills had doubled, tripled or quadrupled — one owner's registered floor area jumped from 76 m² to 126 m² on a house he said he had not altered in 13 years — and a city councillor attacked the lack of advance explanation. The city's answer was technically correct and politically insufficient: the rate had not risen, only the recorded area. A survey that arrives as a bill is remembered as a bill.

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 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.

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.

Published field

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.

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%.

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.
