What National Cadastre & Mapping Agency S.A. does

The National Cadastre & Mapping Agency S.A. (Ν.Π.Δ.Δ. ΕΛΛΗΝΙΚΟ ΚΤΗΜΑΤΟΛΟΓΙΟ / Hellenic Cadastre) is a Greek Legal Entity of Public Law established in 1995 under Law 2308/1995 and reorganized in 2018 under Law 4512/2018, operating as the sole statutory authority for property rights registration and cadastral mapping throughout Greece. Headquartered in Holargos (Athens) under the supervision of the Ministry of Digital Governance, the agency operates a national infrastructure of 17 Cadastral Offices and 75 branch offices serving citizens, notaries, lawyers, engineers, judicial officers, and public-sector entities across all 13 Greek regions. Its mandate is to replace the legacy fragmented system of 390+ private notary-supervised mortgage offices (Υποθηκοφυλακεία) with a unified, digitized national cadastre providing both legal title data and spatial property boundaries.

The agency's technology stack is centered on the Integrated National Cadastre Information System (ΣΠΕΚ), a unified digital database connecting all Cadastral Offices in real time, supplemented by an OGC-compliant Web Mapping Service (WMS 1.1.0) in WGS84, the HEPOS Greek GNSS satellite positioning system for high-accuracy property boundary determination, the INSPIRE Geoportal for EU-compliant open spatial data, an Orthophoto Viewing Service, and a Mobile GPS Property Location application (accuracy 3-10 meters). In 2025, it completed full migration of all systems and data to the National Government Cloud (G-Cloud) and partnered with Vodafone Greece to upgrade the integrated information system; it also launched a beta AI-powered Digital Assistant for citizen inquiries. Additional operational technology includes the Tele-detection Periodic Mapping System covering 270,000 stremmas in fire-affected North-Eastern Attica, which detected 980 unauthorized construction cases between 2010 and 2019.

The agency's revenue model is entirely fee-based, with no subscription or recurring component. Cadastral declaration fees are €35 per property right (€20 for auxiliary spaces such as warehouses and garages), Cadastral Property Certificates (ΠΚΑ) are €5 per property issued electronically via ktimanet.gr using TAXISnet credentials, correction requests during the 2-month posting phase are €5, and apparent error corrections are free. All fees are statutorily regulated under Greek law. Distribution is hybrid: a primary online self-service channel (ktimanet.gr, akinita.gov.gr, support.ktimatologio.gr), 17+75 physical offices, a call center at 210 65 05 600, mobile applications, and a network of professional intermediaries (notaries, lawyers, engineers) who submit transactions on behalf of clients. The agency funds itself through these regulated fees, state budget allocations, and EU co-funding under ESPA operational programs. As of 2025-2026, it has achieved full operational nationwide coverage under Law 4512/2018.

Others

• Esri: Global GIS software vendor whose ArcGIS platform supports many national mapping and cadastral workflows. Not a direct peer, but an enabling technology provider whose tools underpin WMS, INSPIRE, and digital cadastral map services similar to those offered by the Hellenic Cadastre.

Emerging players

• Ordnance Survey (United Kingdom): UK's national mapping agency providing geospatial data, basemaps, and surveying infrastructure. Comparable on the mapping/geodata side (orthophotos, basemaps, APIs) but does not perform statutory land registration.
