Sector Maps
Initial project and official maps by neighborhood or sector

Register and publish maps of sectors, neighborhoods, and blocks so professionals and taxpayers can view boundaries, download plans, and follow official versions of the territorial cadastre.

Access options
Territorial lookup by map, listing, or property record

Citizens and professionals can reach the information through different paths: an interactive Leaflet and OpenStreetMap view, territorial map listings, IPTU/property code, or the owner logged-in area.

🗺
Leaflet / OpenStreetMap map

On-screen viewing with cadastral layers over an OpenStreetMap base map, lot selection, and property record opening.

Territorial listing

Lookup by neighborhood, sector, block, or published version, with access to official maps for viewing or download.

Integrated Flow
End to end — no separated systems
📡
Step 01
Field Collection

RTK GPS, total station, or simple GNSS. The FieldCollect app records vertices with CTM_URBANO or CTM_RURAL precision class.

📈
Step 02
Topographic Processing

Imported points are validated and approved by the responsible technician. Technical documents (plan, memorial, ART) are generated with full traceability.

🏠
Step 03
CTM Cadastre

The survey creates or updates the parcel in CTM. SQL code, PostGIS geometry, owner, and urban attributes are linked.

🌐
Step 04
Public Portal

Citizens consult their property through the interactive map. Public data is visible to everyone; restricted data follows configurable access levels.

Field Collection
FieldCollect — the app that feeds CTM

While SGSis manages the cadastre in the office, FieldCollect captures coordinates directly in the field — and points reach the system ready to generate parcel geometry.

Works offline

Records points without internet. Syncs with the server as soon as the connection returns — essential for rural areas and uncovered perimeters.

🎯
Cadastral precision

CTM_URBANO, CTM_RURAL, and CTM_REFERENCIA classes. The app validates whether the receiver meets the minimum precision before recording the vertex.

📊
Direct import

Collected points reach the topographic survey in SGSis via API. No manual CSV export — the flow is continuous.

📷
Georef. photos

Photos linked to each point or to the entire parcel, with coordinate and timestamp stored in metadata. Audited field evidence.

Capabilities
What SGSis CTM delivers
📌
PostGIS Geometry

Polygons stored in a geographic database with SRID support, automatic area calculation, and spatial queries (ST_Within, ST_Intersects).

👤
Ownership History

Each property transfer is recorded with date, fraction, and relationship type. No history is lost.

📄
NBR 14.166 Compliance

Data structure aligned with the Brazilian CTM standard. Object types, statuses, and minimum attributes are already configured.

🔒
Access Control

Public, authenticated, and internal layers. Citizens see address and area; public servants see owner and assessed value.

👥
Multi-tenant

Supports multiple municipalities on the same platform or on a dedicated VPS per municipality. Data is fully isolated by organization.

🔁
Topography Integration

The topographic survey is the pre-cadastre. Approved GNSS points directly feed the parcel geometry in CTM.
